Answer:
Cell differentiation is the process by which dividing cells change their function. DNA is essential in gene expression, which gives the ability of cells that are specializing to be able to adequately perform the role they are trying to carry out. It is generally understand that all the cells in our body contain the same DNA, yet they carry out different functions. The key is understanding that specific parts/combinations of the genome are activated which changes the function and shape of the cell. Additionally, if the DNA is damaged or mutated in certain areas of the chromosome, it can cause certain differentiated cells to not function properly.

Answer:
Yes.
Explanation:
Yes, there is same effects of isotonic, hypotonic, and hypertonic extracellular environments on plant and animal cells because both cells are more similar to each other. If a plant or animal cell is placed in a hypertonic solution, water will go outside the cell, and the cell will shrink, in isotonic environment, there is no water movement inside or outside of the cell, so there is no change in the size of the cell, while on the other hand, if a cell is placed in a hypotonic environment, water will enter the cell, and the cell will turgor.
The answer is.d. stromatolites hope it help
<em>In the inner medulla, urea recirculates, creating a greater osmotic gradient. It follows the concentration gradient formed by ADH-sensitive water reabsorption into the interstitial space from the collecting duct. The remaining water is drawn from the descending structures by increased interstitial osmolarity. </em>
<em></em>
<em>To maintain the vertical osmotic gradient, the blood supply to the renal medulla serves as a countercurrent exchanger. - The medullary vertical osmotic gradient is maintained by the vasa recta.</em>
<em></em>
<em>It enhances both water and urea permeability in the inner medullary collecting ducts, allowing urea to diffuse passively down its concentration gradient into the interstitial fluid. This contributes to the osmotic gradient and aids water absorption.</em>
