By breaking down food particles gradually
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.
B. Plastron is the bottom half of a turtle's shell
If two species of tertiary consumers are living together in a community, there build a competition between them.
Tertiary consumers feed on primary and secondary consumers and there is no one to feed on them hence named as Apex consumers.
If two consumer species are living together, there will be limited amount of food source which will give birth to competition and which might to lead extinction of one specie.
No, the diffusion distance does not differ between the cubes.
<u>Explanation:</u>
Diffusion is the process by which materials get transported from higher concentration to lower concentration. How much ever the cube size is the rate of diffusion remains the same. Depending on the size the diffusion will not happen at once. The more the volume and lesser the surface area diffusion take a longer time.
To transport the materials through the cells through diffusion takes longer time and hence higher organisms have specified organs to help them in this diffusion.
