Where does the energy for photosynthesis come from?
Answer:
From the sunlight (together with CO2 and water)
Explanation:
Photosynthesis is a process performed by the plants (also some algae and bacteria) in which the energy of sunlight is transformed into chemical energy usable by those plants. Necessary components of this set of reactions are sunlight, water and CO2, while resulting products are glucose and oxygen. Products of photosynthesis are then used in the metabolic processes known as cellular respiration. During the cellular respiration, glucose and oxygen are used for the production of ATP, CO2 and water. Cellular respiration is performed in all living organisms.
Photosynthesis occur in the chloroplast, membrane organelles with photosynthetic pigments (such as chlorophyll).
The energy for photosynthesis comes from the sun. Plant-based organisms capture this energy and convert it into a form that is usable by all life through a process known as photosynthesis. This process underpins much of the energy transformation that supports life.
Explanation:The energy for photosynthesis comes from the sun. In this process, green plants, algae, cyanobacteria, and photosynthetic protists capture solar energy and convert this into chemical energy necessary for life - a process known as photosynthesis. This process transforms the radiant energy in sunlight into stored chemical energy.
Part of this process involves using light energy from the sun to transform carbon dioxide and water into glucose and oxygen. Other organisms consume these glucose-bearing plants and use the glucose to create ATP, a molecule used for energy storage in cells.
Overall, it's the energy from the sun that is harnessed through the process of photosynthesis that provides most of the energy required by living organisms on earth. Without the solar energy captured during photosynthesis, life as we know it would not exist.

Tadpoles must undergo a major metamorphosis to become frogs. This change includes reabsorption of the tail, growth of limbs, calcification of the skeleton, increase in rhodopsin in the eye, development of lungs, change in hemoglobin structure, and reformation of the gut from the long gut of an herbivore to the short gut of a carnivore. Amazingly, all of these changes are induced by thyroxine. What is the most likely explanation for such a wide array of effects of thyroxine?
Answer:
There are many receptors for thyroxine on different target cells (tissues), so its effect can be huge
Explanation:
Target cell for a certain hormone is a cell that have hormone receptor specific for that hormone. There are two main types of receptors on target cell:
cell membrane receptors (also called trans membrane receptors)-usually for peptide hormones, such as insulinintracellular receptors (also called nuclear receptors)-usually for steroid hormones, such as testosterone.Hormone binding to the receptor leads to the signal cascade within the cell, which results in cell response.
Receptors for thyroid hormones are nuclear receptors.

What is the part of the cell cycle process by which chromosomes in a cell nucleus are separated into two identical sets of chromosomes
Answer:
Mitotic phase
Explanation:
Cell cycle is composed of interphase and mitotic phase. Interphase is aphase of cell preparation. It is subdivided into:
G1 (gap 1 phase)-the cell grows and becomes largerS phase- replication of DNA, duplication of centrosomesG2 (gap 2 phase)-proteins and oranelles are madeMitotic phase is phase of cell division, chromosomes are separated, daughter cell get identical sets of chromosomes. It is followed by cytokinesis-separation of cytoplasm. Stages of mitosis are:
prophase-condensation of chromatin into chromosomes, the nuclear envelope breaks down, mitotic spindle formationmetaphase-the chromosmes line up (metaphase plate)anaphase-the siste chromatides move toward opposite cell polestelophase-the nuclear envelope forms again, cell division is almost completeOlfactory information is sent to all of the following areas except the __________.
Answer:
Forebrain.. Which also includes thalamus.
Olfactory information is sent to all of the following areas except the medulla. This sensory information travels through unique pathways, which include direct connections to the olfactory cortex and related structures without the obligatory thalamic relay that is typical for other senses.
Olfactory receptors in the nose pick up odorants and send signals to the olfactory bulb. The olfactory bulb then routes these signals to several brain regions, including the olfactory tubercle, the medial dorsal nucleus of the thalamus, the orbitofrontal cortex, and directly to the olfactory cortex and related temporal structures like the hippocampus. These pathways are unique in that they do not require the thalamus for initial processing, unlike other sensory systems. Olfactory information is also involved in various functions such as odor discrimination, and emotional, motivational, and memory-related aspects of smell, which are processed by areas of the brain dealing with memory, emotions, reproduction, and thought.

Answer:
cytosol (intracellular fluid), interstitial fluid, plasma
The body fluids should be ranked based on their volume in the human body as follows: intracellular fluid (cytosol) the most, followed by interstitial fluid, and plasma the least.
Explanation:The question is asking to rank the main locations where fluids are found in the human body, from the most prevalent to the least. In terms of volume, the majority of bodily fluids are located in the intracellular fluid compartment, which includes the fluid within cells, mainly the cytosol. The next largest volume is the interstitial fluid, which surrounds and bathes all of the body's non-blood cells. Finally, plasma, which is the fluid component of blood, accounts for the least volume of the three mentioned.
Therefore, the correct ranking of these body fluids from the one that accounts for the most in the human body to the one that accounts for the least is:

A gardener purchased 20 full-grown pea plants. All 20 were the same genotype and had purple flowers. The gardener crossed two of these plants to get seeds for the next season. The seeds from the cross produced some plants with purple flowers and some with white flowers. The gardener learned that in pea plants the allele for purple flowers (P) is dominant of the allele for white flowers (p). What was the most likely genotype of the original 20 full-grown plants?
The original 20 full-grown plants’ genotype would have to be (1,2). When you make a Punnett square crossing two heterozygous, you see that you get these as a result: (1,1) (1,2) (1,2) and (2,2). Only the (2,2) can be white therefore it’s a 1/4 possibility of getting white flowers by crossing two full-grown purple pea plants.
"Pp" is the likely genotype of the original 20 full-grown plants.
What is Genotype?An organism's genotype is defined as the complete set of its genetic material, which can also be used to refer to alleles, or variants, that occur in a particular gene or genetic locus. This is also called as the Genetic makeup of the organism.
For above given information,
All 20 fully grown pea plants have purple flowers. But when two of these 20 plants are mixed, the seeds of the cross produce some plants with purple flowers and some with white flowers. So, the 20 plants have purple color which must be carrier of white color allele. Thus, genotype of all the 20 pea plant species would be "Pp"
if these two "Pp" genotype plants are crossed following offspring's are produced -
PP Pp
Pp pp
Since "p" is a recessive allele , so when these two recessive alleles are together they express their trait. So, one out of four offspring is white in color.
Thus, "Pp" is the likely genotype of the original 20 full-grown plants.

Once a carousel is in motion, the constant movement of the carousel horse around the center of the circle can BEST be described as A) acceleration; change in speed. B) velocity; speed plus direction. C) acceleration; change in velocity. D) speed; distance traveled over time.
Answer:
its D
Explanation:
the facts are just all there
Answer:
C) acceleration; change in velocity.
Explanation:
When an object is moving around in a circulation motion with constant speed then even if the movement is constant still the velocity is changing at each point because of the change in the direction at each point. If the velocity is changing at each point then that means the object is accelerating.
But, in linear motion if an object has constant movement then the acceleration is considered zero because there is no change in the direction so velocity change is considered zero.
Since the carousel in this question is moving in the circular motion so it means that its direction is changing at each point which implies that its velocity is changing leading to acceleration.

Which of the following best illustrates ecological succession? See Concept 54.3 (Page 1227) View Available Hint(s) Which of the following best illustrates ecological succession? See Concept 54.3 (Page 1227) Decomposition in soil releases nitrogen that plants can use. Grass grows on a sand dune, is replaced by shrubs, and then by trees. Overgrazing causes a nutrient loss from soil. Introduced pheasants increase, and native quail populations disappear. A mouse eats seeds, and an owl eats the mouse.
Answer:
The correct option is this: GRASS GROW ON A SAND DUNE, IS REPLACED BY SHRUBS AND THEN BY TREES.
Explanation:
Ecological succession refers to the gradual process by which the living organisms in a particular environment are replace overtime. Succession usually occurs as a result of disturbance to the original environment. Ecological succession can be termed as primary or secondary succession based on the type of environment in which the succession occur. One unique features of ecological succession is that lower living organisms are usually replaced with advanced living organisms as time goes on. For instance, in option D, the grasses were replaced by shrubs, which are also later replaced by trees.
The scenario of grass being replaced by shrubs, and then trees on a sand dune exemplifies ecological succession, specifically secondary succession.
Explanation:The example that best illustrates ecological succession is: 'Grass grows on a sand dune, is replaced by shrubs, and then by trees.' This process is an instance of secondary succession, where an area that previously supported life and has nutrient-rich soil undergoes a series of changes in its community structure over time. Initially, pioneer species like grasses colonize the area, which is then followed by a succession of plant communities including shrubs and finally trees, leading to a more complex ecosystem.
Why do most organisms live in the neritic zone
The neritic zone is the zone in the water bodies that is by far the richest in marine life. This zone is occupying the shallowest part of the oceans, representing the waters above the continental shelf up until the drop off of the continental shelf, having maximal depth of roughly 200 meters. This makes this zone very good for the marine life because of two major reasons, one being the sunlight, and the other being warmth of the water. Because the neritic zone is shallow, the sunlight manages to penetrate through it, thus it enables the producers to be able to perform photosynthesis. Since the producers are the basis of all ecosystems as they are the ones that produce the most energy and are primary food source, that means that all the other organisms can prosper as well. Also, the fact that this zone is shallow means that the water is warmer, as the sunlight manages to affect most of it, thus making it warmer and much better for life than the other deeper zones that are much colder.
Upon eating a hamburger in what organ is the chemical breakdown of its proteins initated
The chemical breakdown of proteins is initiated in the stomach by the enzyme pepsin and continues in the small intestine with additional enzymes from the pancreas.
Where Is the Chemical Breakdown of Proteins Initiated?
The enzyme pepsin, which is activated from its precursor form pepsinogen in the presence of hydrochloric acid (HCl), starts the process by breaking down proteins into smaller chains called polypeptides. This chemical reaction is crucial for protein digestion, allowing amino acids to be eventually absorbed into the bloodstream. As the partially digested proteins pass into the small intestine, they encounter additional digestive enzymes from the pancreas such as trypsin and chymotrypsin, which continue the process of breaking down the proteins into even smaller peptides and eventually into amino acids. These amino acids are then absorbed through the intestinal wall and into the bloodstream, where they are carried to the liver for further processing.
The majority of glomeruli are located in the ________ of the kidney.
A) vasa recta B) medulla C) cortex D) pelvis E) calyces
The answer is C) cortex
The majority of glomeruli are located in the cortex of the kidney, where they form part of the renal corpuscles and are adjacent to the tubular structures involved in urine formation.
Explanation:The majority of glomeruli are located in the cortex of the kidney. This region of the kidney houses all of the renal corpuscles as well as the proximal convoluted tubules (PCTs) and distal convoluted tubules (DCTs). Some nephrons within the cortex are termed cortical nephrons and have a shorter loop of Henle that does not extend beyond the cortex, whereas about 15 percent of nephrons, which are called juxtamedullary nephrons, have long loops of Henle that plunge deep into the medulla.
The other options provided do not accurately describe the location of the majority of glomeruli. The vasa recta and medulla house the renal pyramids and longer loops of Henle associated with juxtamedullary nephrons, pelvis is the area into which the renal pyramids drain before connecting to the ureter, and calyces are the chambers that collect urine before it passes into the renal pelvis.

In general, sympatric speciation requires the action of _____ selection acting against hybrids.disruptivedirectionalecologicalartificialstabilizing
Answer:
disruptive
Explanation:
Sympatric speciation is a speciation (evolution of new species) that occurs when one group of population becomes isolated, but stays in the same geographic location as the rest of the population. Through time, these two group evolve independently and become different species.
The model that shows this type of speciation involves disruptive selection: homozygous individuals are favoured over heterozygous in a population, which leads to speciation.
Sympatric speciation generally requires disruptive selection, which favors extreme phenotypes, leading to reproductive isolation and creation of new species within the same habitat.
Explanation:In general, sympatric speciation requires the action of disruptive selection acting against hybrids. Disruptive selection plays a crucial role in sympatric speciation by favoring extreme phenotypes over intermediate ones, thereby driving the divergence within a population sharing the same habitat. This pattern of selection can eventually lead to reproductive isolation and form new species without physical barriers. It contrasts with directional selection which favors one extreme phenotype and stabilizing selection that favors the intermediate phenotype, or artificial selection that is influenced by human choice.

This structure provides support and protection for plant cells.
Answer:
The cell structure that is been described in the question is CELL WALL.
Explanation:
The cell wall is one of the cell organelles that are found only in plant cells. Plant cell walls are made up of a polysaccharide called cellulose. The cellulose gives rigidity to the plant cell wall and enhances its ability to provide structural support for plant cells. The plant cell wall also serves as a barricade that protect the cell from invasion by foreign bodies.
The plant cell wall is the structure that provides support and protection for plant cells.
The plant cell wall has three functions: it supports the structure of the plant as a whole, protects individual cells by acting as an enclosure, and facilitates fluid flow by assisting in the formation of channels inside the plant.
The cell wall isolates the inner elements from the surrounding environment. The cell and its organelles are also given form, support, and protection by it. But only eukaryotic plants, fungi, and a few prokaryotic creatures have this cellular component.

When ATP is broken down in cells, __________ and __________ are the products.
A. adenosine diphosphate; a phosphate group
B. adenosine monophosphate; three phosphate groups
C. adenosine triphosphate; a phosphate group
D. adenosine diphosphate; three phosphate groups
Final answer:
When ATP is broken down, it produces adenosine diphosphate (ADP) and an inorganic phosphate group (Pi). This process releases energy due to the lower free energy of the products compared to the reactants.
Explanation:
When ATP is broken down in cells, the products are adenosine diphosphate (ADP) and an inorganic phosphate group (Pi). This process is known as hydrolysis, which is the reaction involving the cleavage of bonds by the addition of water. ATP, consisting of an adenine, a ribose, and three phosphate groups, releases energy when the bond between the second and third phosphate groups is broken. This energy release occurs because the products, ADP and Pi, have considerably lower free energy than the reactants, ATP and a water molecule. Hence, the correct answer to the question is:
A. adenosine diphosphate; a phosphate group
A new object, Object Y, was discovered outside our solar system. Object Y is small and rocky, is not a satellite of any other object, and it does not have enough gravity to clear away smaller objects near its orbit. The characteristics of Object Y most closely resemble those of other (2 points)
comets.
dwarf planets.
moons.
meteors.
Answer:
The correct answer is comets.
Explanation:
Comet is an icy, small, and rocky bodies found in space, which discharge gas or dust. They are also called dirty snowballs. It is not considered as the satellite of other objects. It does not exhibit adequate gravity to clear away smaller objects close to its orbit. When it passes close to the Sun, it sheds extra of its ice, and its surface may get surrounded with darkish dirt and would seem more like an asteroid.
Final answer:
The characteristics of Object Y—being small and rocky, as well as its inability to clear its orbit—most closely resemble those of dwarf planets within our solar system.
Explanation:
The characteristics of Object Y most closely resemble those of other dwarf planets. Like Object Y, dwarf planets are small and rocky objects that do not have enough gravity to clear away smaller objects near their orbits. Although comets, asteroids, and meteors are also part of our solar system's collection of smaller objects, they each have distinct features that do not match the description of Object Y as closely as dwarf planets do. Comets are mostly icy and have elliptical orbits that can bring them close to the Sun, producing visible tails and comas. Asteroids are rocky like Object Y, but the term typically refers to those found within the asteroid belt between Mars and Jupiter, and they do not have the criterion related to clearing their orbits. Meteors are much smaller, often vaporizing in Earth's atmosphere, and moons are objects that orbit planets, which is not the case for Object Y.
