Answer:
D.evaporation of sweats warm the body.
Explanation:
It doesn't warmed the body, it races the heart beat when a person is being actively moved or doing something with great strength.
Evaporation of sweat warms the body is not true about the process of sweating.
Explanation:
The main function of sweat is to reduce the elevated body temperature which is more than the normal body temperature of human body that is 37.2 degree Celsius. The sweat glands present all over skin and when the temperature rises the sweat is released. As the sweat gets evaporated from skin surface, the skin becomes cool. The content of sweat includes water and some salts.
Excessive sweating can leads to dehydration during the summer. During exercise the temperature of the body increases due to which the sweat is released from the sweat glands.
Osmosis (pick the incorrect statement) Osmosis is the passive transport of water from an area of low solute concentration to an area of high solute concentration. The movement of water across a cell membrane requires transmembrane integral proteins. The osmotic pressure between two compartments is determined by the relative concentrations of the permeant solutes in the compartments. Cells regulate water and ion balance by actively transporting ions but not water.
Answer:
Cells regulate water and ion balance by actively transporting ions but not water.
Explanation:
Cells regulate water and ion balance by transporting the water molecules from a region of of high concentration to a region of low concentration passively. Active transport does not maintain the water and ion balance, so the last statement is incorrect.
Rest of the statements are correct.
In the first statement they are saying that in osmosis water from an area of low solute concentration moves towards an area of high solute concentration which is absolutely right. An area which has a low solute concentration has a high solvent concentration and vice versa. In osmosis, only solvent can move because osmosis occurs by means of a semi permeable membrane which does not let a solute molecule to pass by. So the area where solute is less, solvent is more and this solvent tends to move towards an area which has high solute concentration because a high solute concentration will have low solvent concentration .
Second statement is also correct. water cannot cross cell membrane because water is polar while cell membrane is non polar. Non polar cell membrane does not let water to pass through it because water is polar therefore water requires integral proteins named as aquaporins to cross cell membrane.
Statement third is also correct. The osmotic pressure is a measure of solute concentration of a particular compartment. The less is the solute in a compartment, the more will be the osmotic pressure. That simply means that osmotic pressure of a pure solvent will be highest because it does not have solute at all. In contrast to this, a solution will have comparatively low osmotic pressure because of the presence of solute in it.
The incorrect statement about osmosis is that water movement across a cell membrane requires transmembrane integral proteins. In reality, water can pass through the cell membrane via osmosis without the need for proteins. Osmosis maintains solute equilibrium on both sides of the membrane.
Explanation:The incorrect statement in your options about osmosis is that: The movement of water across a cell membrane requires transmembrane integral proteins. In truth, water can pass through the cell membrane via a process called osmosis without the need for proteins. Osmosis is the passive transport of water molecules from an area of low solute concentration to an area of high solute concentration. The aim is to maintain equilibrium in the solute concentration on both sides of the membrane. The osmotic pressure difference between two compartments is created by the relative concentrations of solutes that can pass through the membrane, known as permeant solutes. Cells do actively regulate ion balance and water via different mechanisms, not just by transporting ions.

Select the correct statement about chemical energy, a term used by biologists to refer to potential energy available for release in a chemical reaction. Light energy is converted to chemical energy during photosynthesis. When a glucose molecule is catabolized to CO2 and H2O, chemical energy is lost. A photosynthetic cell within a plant leaf produces chemical energy, stored within glucose molecules.
Answer:
A photosynthetic cell within a plant leaf produces chemical energy, stored within glucose molecules.
Explanation:
The energy captured from sunlight by Photosystems in chlorophyll is used to split a water molecule and reduce carbon dioxide to carbohydrates. This energy from sunlight is therefore stored in the chemical bonds of the glucose molecules. It is thereafter harnessed during cellular respiration when the chemical bonds of glucose are broken and the energy transferred to make ATP molecules.
Answer:
Option A , Light energy is converted to chemical energy during photosynthesis.
Explanation:
In the process of photosynthesis, a plant containing chlorophyll converts solar light energy into chemical energy.
The common reaction of photosynthesis is
Carbon dioxide + Water + energy from sun ------> Glucose + carbon dioxide
Thus, energy from sun is used to excite photon with in the thalokoid of plant cell to initiate photosynthesis and then as a result of this process food (glucose containing chemical energy ) and carbon dioxide is formed.
Hence, option A is correct
why did the finches found on the galapagos islands have different shaped beaks?
A.the birds were not all finches
B.the birds evolved at different times
C.the birds had different diets
C. The birds had different diets. The bird's beaks evolve depending on their diet!
Sunny~ ☺
Answer:
c. the birds have different diets
Explanation:
The research that Darwin had at Galapago´s Islands, brought up several questions about why are living species the way they are. As part of the theory of Natural Selection, Darwin supported that the physical characteristics of the individuals are strictly related with their function. For example, the shape of the beak of the finches, which is a consequence of evolution, has a strict relation with the type of diet they have and as a consequence, the adaptation they will have in their environment.
Which of the following statements about amino acids is INCORRECT?
A turn or kink in a protein is more likely to be induced by a proline than by a glycine.
The more glycines that are found in a polypeptide's primary sequence, the more flexible the backbone of that polypeptide.
The bridge between cysteines, which connects parts of a protein, is a stable but noncovalent interaction.
Not every amino acid is asymmetric.
At typical cellular pH, the R groups of basic amino acids are positively charged.
Answer:
The answer is: The bridge between cysteines, which connects parts of a protein, is a stable but noncovalent interaction.
Explanation:
Hope my answer has helped you!
Final answer:
The incorrect statement is that the bridge between cysteines in proteins is a noncovalent interaction; it is actually a covalent bond known as a disulfide linkage, crucial for protein tertiary structure stabilization.
Explanation:
The incorrect statement among the choices provided for amino acids is that the bridge between cysteines, which connects parts of a protein, is a stable but noncovalent interaction. In truth, the bridge between cysteine residues is formed by a covalent bond known as a disulfide linkage. This link is a result of the oxidation of two cysteine molecules, which combine to form cystine, and it is significant in stabilizing a protein's tertiary structure.
A turn or kink in a protein is indeed more likely to be induced by a proline than by a glycine, due to proline's ring structure. Glycine, having a single hydrogen atom as its side chain, is small and allows flexibility in the protein structure, making the backbone of the polypeptide where glycines are present more flexible. Not every amino acid is asymmetric; for instance, glycine is not chiral. At typical cellular pH, the R groups of basic amino acids such as lysine and arginine are indeed positively charged.

What is the main sugar used by cells for energy?
Answer:
The answer is GLUCOSE.
Explanation:
Glucose is the main sugar used by cells for energy. Glucose is derived from the digestion of carbohydrates. In humans, glucose is usually absorbed into the blood from the small intestine, the blood then carry the blood around the body, allowing each cell to have access to the glucose it needs.
If the quantity of glucose in the blood is more than needed per time, the body usually store the excess glucose as glycogen, the glycogen will be turned to glucose and release for cell use when the quantity of sugar in the blood is low. In the absence of glycogen, other macro nutrients such as lipids and proteins can also be converted to glucose via gluconeogenesis when the concentration of glucose in the blood is low.
The cells oxidize the glucose and convert it to energy in form of ATP, which they use to carry out their life activities.
The main sugar used by cells for energy is glucose. It can be stored as glycogen in the body or it is converted into fat if in excess. During cellular respiration, it helps to form ATP, the cells' energy currency.
Explanation:The main sugar used by cells for energy is glucose. This simple sugar, a monosaccharide, is an important energy source for many organisms. Carbohydrates, such as sugars, are the most common source of energy for the body, broken down during digestion into simpler monosaccharides like glucose and fructose.
Once glucose is in the body, there are a series of endocrine control mechanisms that regulate its concentration in the bloodstream. Excess glucose can either be stored in the liver and skeletal muscles as a complex polymer called glycogen, or it can be converted into fat in adipose cells or adipocytes.
During cellular respiration, energy is released from glucose. This energy helps to form adenosine triphosphate (ATP), which is like the currency that cells use for energy. Photosynthetic plants synthesize glucose using carbon dioxide and water, and the glucose is then used for their energy requirements. Any excess synthesized glucose is often stored as starch, which can be broken down by other organisms that feed on plants.

One of the major complications of diabetes is delayed wound healing. People with diabetes also often experience neuropathy—numbness or loss of sensation on the extremities—especially the feet. What medical complications can arise from slow wound healing and neuropathy of the feet?
Explanation:
Slow healing : pathogens can enter the open wound and cause infections, worsening the wounds. If the problem continues, parts of body will require removal(cutting off).
Neuropathy: as the sensations are loss, receptors no longer react to contact stimuli & reflexes can't be conducted on time for survival pruposes. For example, if the skin touches a hot object, the receptors on skin will not react to the heat & remove itself away from the stimuli.
One of the major complications of diabetes is delayed wound healing. People with diabetes also often experience neuropathy—numbness or loss of sensation on the extremities—especially the feet. The slow wound healing can cause infection and neuropathy can cause complete loss of feeling.
What are peripheral neuropathy and infection?Peripheral neuropathy is one of the common causes of diabetes. It is the result of damage to peripheral nerves which leads to numbness, pain, and weakness in hands and legs.
Wounds that are not healing or wounds that are very slow healing are caused majorly by diabetes because they have a problem with the activation of the immune system.
If the immune system cannot function in the right way, then wound healing can take more time and are at high risk for infection.Peripheral neuropathy also known as diabetic neuropathy on the other hand is another severe issue a diabetic person can experience.Peripheral neuropathy can ultimately cause no feeling in hands and legs that can make them paralyzed at some point of their lifetime.To learn more about diabetes, refer:

Why are well-defined reading frames critical in protein synthesis? A. Without a well-defined reading frame, the mRNA would be transcribed back into DNA. B. Without a well-defined reading frame, the ribosome is unable to bind to the mRNA. C. Without a well-defined reading frame, the peptide made from a given sequence could be completely different. D. Without a well-defined reading frame, the resulting protein would be transported to the cell surface.
Answer:
C
Explanation:
During the translation of an mRNA, it is read in a sequence of three nucleotides called codons. Therefore, a single strand of DNA or RNA will have three reading frames. Only one is biologically relevant and is referred to as the open reading frame because it is translated to the ideal protein. A shift in the reading of the frame can result in a wrong peptide.

asteroids
meteorites
Answer:
Bodies of interplanetary debris that orbit the Sun with most in the area between Mars and Jupiter are called comets.
Answer: Option (3)
Explanation: The region between the inner planets and the outer planets, i.e between Mars and Jupiter, there lies a belt known as the asteroid belt. These asteroids ranges in size from a few meters to hundreds of km. The asteroids in this belt, generally moves at a speed of about 80,000 km/hr and there occurs frequent collision between them.
Thus, the correct answer is option (3).
A particular triplet of bases in the template strand of dna is 5′-agt-3′. What would be the corresponding codon for the mrna that is transcribed? A. 3 UCA 5 B. 3 UGA 5. C. 5 TCA 3 D. 3 ACU 5
Answer:
3 UCA 5
Explanation:
The 5' end of a strand pairs up with the 3' of its complimentary strand. So with this fact, we can rule out option C.
Now when you pair the DNA template with the mRNA template, remember that RNA contains uracil and not thymine. So the base pairings would be:
T = A
A = U
U = A
G = C
C = G
Based on this, the pairing would be like this:
5' A G T 3'
3' U C A 5'
The corresponding mRNA codon to the DNA triplet 5'-AGT-3' is 5'-UCA-3', which is option A. 3' UCA 5'.
Explanation:When transcribing DNA to mRNA, the bases are matched in the following way: adenine (A) pairs with uracil (U), thymine (T) pairs with adenine (A), cytosine (C) pairs with guanine (G), and guanine (G) pairs with cytosine (C). Therefore, for the DNA triplet 5'-AGT-3', the corresponding mRNA codon would be the complement of this sequence, transcribed in the antiparallel direction, which is 5'-UCA-3'. So, the correct answer is A. 3' UCA 5'.
Which activity occurs when a flowering plant reproduces?
Hello There!
Flowering plants reproduce through the process called pollination. There are many different types of pollination
Answer:
Flowering plants require the formation of reproductive structures and pollination.
Explanation:
For flowering plants to reproduce, first the reproductive structures have to form (pistils and stamens) and then the pollen has to be taken from the first flower to the second or where the fertilization will happen. There are several ways to pollinate, including insects, or bigger animals like bats. After the animal is taking the pollen to another flower, it is fertilized and starts to transform into a fruit, where, later the seeds will also be carried by animals.

Which statements correspond correctly to sexual reproduction?
the potential combinations are unlimited
variations have no boundaries
new genetic information is originated at fertilization
variations remain within created kinds
all genetic information comes from preexisting genes
Final answer:
The correct statements relating to sexual reproduction are that the potential combinations are indeed unlimited, variations have no boundaries, and although new genetic combinations arise, all genetic information derives from preexisting genes, and variations remain within created kinds.
Explanation:
In sexual reproduction, the combination of genetic material from two parents leads to offspring that have unique genetic makeups. The processes that contribute to this diversity include crossing-over during meiosis, independent assortment of chromosomes, and the random union of gametes at fertilization. As a result, sexual reproduction has the potential to produce a vast array of genetic combinations.
Regarding the given statements, we can say that the following are correct:
The potential combinations in sexual reproduction are indeed unlimited.Variations indeed have no boundaries due to the random nature of genetic recombination and gamete fusion.While new genetic information is not exactly originated at fertilization, the unique combination of existing genetic information from two parents does create a new genotype.Variations do remain within created kinds, meaning species tend to produce offspring within the same species.All genetic information indeed comes from preexisting genes; the combination of these genes, however, results in unique individuals.which of the individuals below would express a recessive trait?
A.Bb
B.BB
C.bb
C. bb
They have two recessive genes and therefore will be expressed.
Even though Bb has one recessive gene it will not show because the dominate overtakes the recessive. They are a carrier of the recessive gene though.

Answer:
Option B, Build more infrastructure including more roads, tolls, and car-pooling lanes.
Explanation:
When an infrastructure is built it allows more vehicle to go through it. It proves to be useful only for some time just after the construction. However, in long run it again proves to be inefficient as efficient traffic management require efficient traffic planning and not construction of more infrastructure.
Also addition of infrastructure, increases the vehicular population thereby adding more vehicles to already existing mismanaged traffic.

Explanation:A short-lived structure formed during a collision in a chemical reaction is known as the activated complex or the transition state. This occurs when reactant particles collide with both proper orientation and sufficient energy. The activated complex is an unstable arrangement of atoms that exists at the peak of the activation energy barrier and has a very brief existence, around 10-13 seconds.
It can either revert to the original reactants or continue on to form products. This state is typically undetectable by standard analytical instruments, although sophisticated spectral measurements can sometimes observe these transition states.
