Answer:

Proteins are large, complex molecules that play many critical roles in the body. They do most of the work in cells and are required for the structure, function, and regulation of the body's tissues and organs. These proteins provide structure and support for cells. On a larger scale, they also allow the body to move.

Explanation:

three major roles of proteins are:

hormones. Many hormones are protein in nature; hormones control growth and metabolic activities of the body.

catalytic activities. Enzymes are globular protein.  

Transport of oxygen.

Blood Clotting.

Immunity.

Ede4ka [16]

Complete question:

Thinking creatively about evolutionary mechanisms, identify at least

two schemes that could generate allelic polymorphism in a population except natural selection that favors heterozygotes.

<u>Select the two correct answers.</u>

-inbreeding among individuals in the population

-purifying selection against mutational variants of alleles in the population

-continuous migration of individuals with new alleles into the population

-mutations that do not severely affect viability and reproductivity

-genetic drift of alleles common in the population

-events leading to genetic bottleneck effect

Answer:

The two events that might favor heterozygotes among the options are  

  • The Continuous migration of individuals with new alleles into the population
  • Mutations that do not severely affect viability and reproductivity.  These might favor heterozygous frequencies.

Explanation:

Due to technical problems, you will find the complete explanation in the attached files.

What happens when hydrogen ions combine with hydroxide ions
s2008m [1.1K]
  Hydrogen ion, or H-, creates water when combined with a hydroxide ion, OH+.
 
    The 'formula' for water is H20, two hydrogens and an oxygen. 

I hope that I helped but if this still makes no sense, or if I haven't explained it as well, then please don't hesitate to ask further questions. Thank you.
