What occurred during immune system development to result in the presence of antibodies that can bind to the thyroid receptor? g
almond37 [142]

Answer:

If the immune system has a destructive and autoimmune response, it produces specific antibodies, which bind to the receptors of the thyroid cells and destroy them thinking that they are antigens or factors not characteristic of the body.

Explanation:

This happens because the thyroid cells do not present on its surface the histocompatibility complex, which is a surface protein similar to the proper and non-proper "seal", that is, it is the demarcation by which the antibodies and the cells are guided to recognize what foreign to the organism.

The histocompatibility complex is sometimes absent or rather mutated, thus generating that these cells are considered not their own and that the antibody is a receptor in order to generate the autolysis pathway or even the immune defense pathway.

Small, isolated populations of collared lizards remain in glades of desert-like habitat scattered throughout the oak-hickory for
dusya [7]

Answer:

Option A

Explanation:

Options

A. most populations were fixed for a single genotype, but genotypes varied among populations

B. average heterozygosity was declining steadily over time

C. individual populations were polymorphic for several loci and most populations were genetically similar to one another

D. all populations were fixed for the same allele at each locus studied

Solution

As per the study conducted by Templeton, it was found that human affect the biodiversity at all biological levels such as genetic, ecosystem, species etc. and behind genetic variation two important factors are genetic drift and gene flow.  

Both the gene flow and genetic drift produce opposite results as genetic drift increase variation with in the species but decrease variation with in the local population and the opposite of this happens in gene flow.  

Genetic drift has actually lead to speciation of collared lizards  among themselves for a specific genotype

Hence, option A is correct
