Answer:

Human blood contains a buffer of carbonic acid (H2CO3) and bicarbonate anion (HCO3-) in order to maintain blood pH between 7.35 and 7.45, as a value higher than 7.8 or lower than 6.8 can lead to death. In this buffer, hydronium and bicarbonate anion are in equilibrium with carbonic acid.

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 has been the biggest cause of biodiversity loss? *
saw5 [17]
Habitat destruction is the key one out of all of these. Animals being kept at the zoo for research are usually endangered or vulnerable species which is doing more good than harm to them. Legal hunting of animals is most likely for rabbits, deer, and a stabilized population in the wild. Habitat destruction can destroy many populations and cause loads of damage. An example of that would be the Australian wildfires at the start of 2020.

Which of the following is true about protein as an energy source? Select one: a. Protein is more important than carbohydrate as
lutik1710 [3]

Answer: b. The use of protein as an energy source is greater for endurance atheletes than those who body build or lift weights.

Explanation:

Proteins are the biomolecules. They are composed of polymers of amino acids. It is required by the body to repair tissues and build muscles, bones, and necessary component of skin, and cartilage.

The body of athletes require more protein than body builder or weight lifters. This is because during athletic practices like running, swimming and others the muscular mass should be strong enough to conduct long continous practice. The muscle mass is build up by proteins. The muscles may experience lack of oxygen during regular practice and may become weak. Thus require more protein so that the strength may remain maintained.
