Answer:
Defective checkpoints results in death of the cell.
Normal checkpoints make sure the cell has enough resources for cell division. Normal checkpoints ensure the cells commits apoptosis if the cell has a problem it cannot fix itself.
Haploid. This means that the cells produced during the second meiotic division contains only one set of chromosomes. During mitotic division, the cells produced are diploid. This means that they contain two sets of chromosome. There is a pair of each chromosome. However, a haploid cell contains only one chromosome out of the pair. The production of haploid cells by the second meiotic division produces gametes or sex cells. It is essential that gametes have only one set of chromosomes since gametes combine during sexual reproduction. It then allows for the correct two sets of chromosomes to be found in the offspring.
Answer:
a. are quick to adapt to a particular stimulus intensity.
Explanation:
Phasic receptors are the one that first generates an action potential in response to the stimulus. However, they adapt to that intensity of the first stimulus and reduce signaling. Slowly, they even stop signaling irrespective of the presence of stimulus of the same intensity.
This is the reason that we get adapted to the specific odor such as gas leakage after some time even if the leakage continues.
Facilitated diffusion is the process of diffusion in which molecules pass across the membrane through call membrane channels. Simple diffusion, is the process by which particles tend to move form an area where they are more concentrated into an area where they are less concentrated. Osmosis is the diffusion of water through a selectively permeable membrane. The water moves inside of the cell if the pressure of water outside is higher, to achieve equilibrium. I hope this fulfills your inquire, and that I may help you next time.
