Answer: For decreased chances of rejection
Explanation:
The three higly polymorphic MHC 1 genes in human beings are HLA-A, HLA-B and HLA-C.
These determine the compatibility of the organ or tissue in the recipient's body each by the help of many alleles that segregates in a population.
There are very less chances that a random chosen donor will match the a recipient six allele genotype.
This is the reason parent may be the best donor for organ transplantation or tissue transplantation.
Answer:
The correct answer would be - Cells begin dividing faster, leading to cancer.
Explanation:
In the process of the cell cycle, there are several checkpoints that ensures that the cell is all set to move to next phase, the cell that not match the requirements cell have not move to next phase.
These checkpoints control the rate of cell proliferation or division and if a dividing cell fails to pass through any checkpoints due to the mutation, it is most likely divide uncontrollably and lead to cancerous or tumor cell.
Thus, the correct answer is - Cells begin dividing faster, leading to cancer.
Answer:
Active transport requires cellular energy for substances to cross the cell membrane; passive transport does not.
Explanation:
Active Transport works against the concentration gradient and therefore needs energy to make it happen
Passive transport such as Diffusion and Osmosis uses the properties of natural movement of particles which moves the molecules from areas of high concentration to areas of low concentration or down the concentration gradient and happens passively without the need for energy
