Long saturated fatty acid tails reduces lipid mobility while
decreases membrane fluidity. It is because this is the saturated fatty acids’
function and if it has reduced the lipid mobility, this will also decrease the
fluidity of the membrane of the individual.
antigen processing involves the breakdown of protein antigens and the subsequent association of peptide fragments on the surface of antigen-presenting cells with MHC class I or class II proteins.
Antigen is any foreign particle or molecule that can trigger a n immune response in the body.
After the body encounters the antigen cells like macrophages, B cells and dendritic cells will recognise and destroy them. The parts of the antigen will be presented by the macrophages to the T cells and hence they are also called Antigen presenting cells.
Antigen presenting cells will showcase the antigen or its part to the T cells. This is done with the help of a protein called major histocompatiblity complex or MHC complex proteins.
MHC proteins are present on cell surface and holds the antigens to showcase them to T cells.

Answer:
<em>In a population, natural selection acts on phenotype of individuals.</em>
Explanation:
Natural selection tends to favour those organisms of a population which carry traits that allow them to be better adapted to the environment and these traits are passed on to their offsprings. Natural selection tends to act on the phenotype of the population whereas evolution is the phenomenon which changes the allele frequencies. Natural selection acts on individual organisms of a population whereas the change in populations, on the whole, arises due to evolution.
If both of mr jone's parents were AB that means mr jone has both alleles for blood type a
Therefore there is a chance of 50% that they will have a child with blood type A.
