Compare and contrast cell differentiation in plant and animal cells
Answer:
Explanation:
There are differences between Eukaryotic and Prokaryotic cells. A Prokaryotic cell does not contain a nucleus. It only contains one chromosome and is a single-celled organism. It was the only form of life on earth for millions of years. Examples of a Prokaryotic cell are the different types of bacteria present today.
A Eukaryotic cell contains a nucleus; more than one chromosome and is typically a multicelled organism. Both plant and animal cells are eukaryotic cells, but there are differences between the two. A plant cell has a cell wall while an animal cell does not have a cell wall. A plant cell is a regular shape and an animal cell is an irregular shape. Both plant and animal cells have a nucleus. There are just a few examples of the differences between Eukaryotic and Prokaryotic cells.
Baby scorpions are born with fully developed bodies, each with many special parts such as a stinging tail. Which process enables baby scorpions to develop various kinds of body parts from a single zygote?
Question 10 options:
meiosis
cell breakdown
reproduction
cell differentiation
The correct answer is cell differentiation
Every organism start as single cell and the single cells divide repeatedly to form adult organism. In the single, there is a DNA; it is the coding for the protein to be used by the adult organisms.
However, all the proteins will keep dividing and undergo a gene expression to become more specific cells. This process is knows as Cell differentiation.
Further ExplanationCell differentiation can be defined as the process in which a cell transforms from one cell type to another. The process involved in cell differentiation enables organisms such as multi-functional organisms to form functional cell types that are very unique and body plans.
The process of cell differentiation is largely motivated by genetics and the way it interacts with the environment.
The organism begins to form from a single cell and the single cell has all the DNA coding required for the proteins to be used by the adult organism.
However, the cells would seize to function if it expressed these proteins at once. For the cell to start the process of differentiation it must divide repeatedly, at this point, the cell line will start to form and the cells will become more and more specific.
As the cells become more and more specific, it will eventually form an organism that has many different cells from the process of cell differentiation.

A geological fold where the youngest rock layer is at the center is known as a syncline, a concave-upward fold with beds dipping towards the center.
A fold where the youngest rock layer is in the center is called a syncline. In geological terms, a syncline is a trough-like or concave-upward fold in which the beds dip towards the fold's central axis. By contrast, anticlines are the opposite, where the oldest rock layers are in the center and the rock layers dip away from the central axis. Synclines often appear as 'U' shaped formations in the Earth's surface and are indicators of the relative ages of strata within folded rock formations.
How does the cell membrane help cells maintain homeostasis
The cell membrane maintains homeostasis by controlling the movement of substances in and out of the cell, allowing cells to change shape as needed and recognizing other cells for tissue and organ formation and immune response.
Explanation:The cell membrane plays a crucial role in maintaining homeostasis within a cell. Homeostasis refers to a state of balance within a living organism, which is essential for the survival and functionality of its cells. A significant function of a cell's
plasma membrane
is to define the cell and determine its interaction with its environment. This membrane is selectively permeable, allowing it to control what substances enter or exit the cell.
Growth and dynamic homeostasis
are maintained through the constant movement of molecules across this membrane. The cell membrane must also be flexible to allow cells to change shape as required by their environment. Lastly, the surface of the plasma membrane carries markers for cell recognition, which is essential for tissue and organ formation, and the distinction between 'self' and 'non-self' in the immune response.

1) One difference between carbohydrates and lipids is that A) Lipids will dissolve in water but not carbohydrates. B) Carbohydrates will dissolve in water but not lipids. C) Carbohydrates contain hydrogen, carbon, and oxygen and lipids do not. D) Lipids contain hydrogen, carbon, and oxygen and carbohydrates do not.
Final answer:
Carbohydrates and lipids both contain carbon, hydrogen, and oxygen, but differ in that carbohydrates will dissolve in water while lipids will not due to their nonpolar hydrophobic characteristics. So the correct option is B.
Explanation:
One difference between carbohydrates and lipids is that carbohydrates will dissolve in water but not lipids. Lipids contain the same elements as carbohydrates, which are carbon, hydrogen, and oxygen. However, lipids are predominantly composed of hydrocarbon chains that are nonpolar and hydrophobic, meaning they do not dissolve well in water, whereas carbohydrates are generally polar molecules which can dissolve in water.
Both lipids and carbohydrates serve as sources of energy. However, they differ in how they store and provide this energy. Carbohydrates generally provide quick energy, while lipids store energy for long-term use. The solubility of lipids is different than that of carbohydrates due to their physical structure and the presence of fewer polar functional groups. Lipids are more soluble in organic solvents, like dichloromethane, due to their nonpolar nature.
a behavior in which animals move toward or away from a light source.
Answer: Phototaxis
Explanation: Phototaxis is the phenomenon by which locomotory movement of the organism occurs towards or away from the stimulus of the light.
This is advantageous for the phototropic organism as they can move efficiently towards the sunlight which helps them to make food by the help of sunlight and other substances.
The phototaxis is called positive if the movement is towards sunlight and negative if the movement is against light.

The elastic rebound theory suggests which of the following?
Answer;
The elastic rebound theory suggest that; Most earthquakes are produced by the rapid release of energy stored in rock that has been subjected to great forces.
Explanation;
The elastic rebound theory was suggested by Henry Feilding Reid, who made observations and summarized that the earthquake occurs as a consequence of an elastic rebound of elastic strain energy that was previously stored in the rocks on either side of the fault.
The elastic-rebound theory explains how energy is produced when an earthquake occurs. According to this theory as adjoining plates on the Earth's surface move in opposite directions, then the rocks which span the opposing sides of the incipient fault are subjected to extreme shear stress.
The Elastic Rebound Theory explains the phenomenon of earthquakes caused by the sudden release of stored energy in strained rocks. When the stress exceeds the rock's strength, it fractures and rebounds, causing an earthquake.
Explanation:The Elastic Rebound Theory explains how energy is stored in rocks and is then released once the rocks crack or rupture, causing an earthquake. This theory is highly related to the study of tectonic plate movements and earthquakes. In a strained rock formation, when the stress exceeds the rock's strength, the rock fractures and subsequently rebounds, causing it to shake or vibrate leading to an earthquake. This displacement or movement of rocks is sudden and rapid, thus the term 'rebound'.

how does atp become adp
ATP becomes ADP through hydrolysis, which involves the breaking of a high-energy phosphate bond by the addition of water, releasing energy. This reaction is reversible; ATP can be regenerated from ADP and phosphate using energy from cellular respiration or photosynthesis.
Explanation:ATP (adenosine triphosphate) becomes ADP (adenosine diphosphate) through a process called hydrolysis. This involves the addition of a water molecule (H2O) to ATP, which results in the breaking of one of its high-energy phosphate bonds. The reaction releases energy that the cell can use for various functions. Specifically, the equation for this reaction is ATP + H2O → ADP + Pi + energy. The inorganic phosphate released is denoted as Pi.
Cells can regenerate ATP from ADP and Pi by reversing the hydrolysis reaction. This reverse process, called phosphorylation, requires an input of energy. It can occur during cellular respiration or photosynthesis, where the energy is sourced from the breakdown of food or absorption of sunlight, respectively. The reverse equation is often expressed as ADP + Pi + free energy → ATP + H2O.
Those phosphate bonds in ATP are high energy because the phosphate groups have negative charges that repel each other. It takes energy to keep them together, and when the bond is broken, energy is released. This is why ATP is often referred to as the energy currency of the cell.
Which of the following plant adaptations is not found in deciduous forests? a. They have broad leaves. b. They can absorb nutrients from the ground. c. They stretch toward the Sun. d. They keep their leaves year round.
Answer: d. They keep their leaves year round.
Plants in deciduous forests have special adaptations for survival in deciduous forests it depends upon the seasonal variations. In winters, because of lack of proper sunlight leaves are shed from the plants. As, without proper sunlight they are not able to conduct photosynthesis also the budding sites where the leaves originate also get blocked in order to prevent water loss through transpiration. Therefore, plants in deciduous forest does not keep their leaves year round.

Photosynthesis produces carbon dioxide, while cellular respiration produces water.
Photosynthesis produces sugar, while cellular respiration produces oxygen.
Photosynthesis produces water, while cellular respiration produces sugar.
Photosynthesis produces oxygen, while cellular respiration produces carbon dioxide
Answer:
Last option.
Explanation:
Photosynthesis can be defined as a process, by which photosynthetic organisms produce their own food (in the form of sugars), by using carbon dioxide and water. During photosynthesis, oxygen is released as a byproduct.
Cellular respiration involves breakdown of complex biomolecules (such as sugars) to produce energy in the form of ATP molecules. During cellular respiration, carbon dioxide, along with water are released as byproducts.
Thus, the correct answer is last option.
The statement 'photosynthesis produces oxygen, while cellular respiration produces carbon dioxide' is CORRECT.
Photosynthesis is a series of metabolic reactions by which plants and algae produce simple carbohydrates (sugars) and oxygen by using the energy from the sun, carbon dioxide and water.
Photosynthesis has two main types of reactions: light-dependent reactions and light-independent reactions.
Moreover, cellular respiration is a series of metabolic reactions by which eukaryotic cells produce energy in the form of ATP by using the energy stored in the chemical bonds from foods, oxygen and water.
Cellular respiration has three main stages: glycolysis, the citric cycle and oxidative phosphorylation.
In conclusion, the statement 'photosynthesis produces oxygen, while cellular respiration produces carbon dioxide' is CORRECT.
