In the Hardy-Weinberg equation, which is:
p² + 2pq + q² = 1
The letter p represents the homozygous dominant genotype and the letter q represents the homozygous recessive genotype.
If the value of either p and q decrease, this means that there is more mixing and interbreeding between the population of species, resulting in deviation from homozygous genotypes. 
This mixing may arise from removed barriers or from selection pressures causing the organisms to move from their original habitats.

Answer:

The population is evolving.

Explanation:

If any sort of change is happening in a variable, allele, gene etc.; then it means that the population is evolving in a certain way.

STatiana [176]

Answer:

The correct option is b. DNA ligase

Explanation:

DNA ligase is an enzyme that joins DNA fragments. If two DNA fragments or molecules have complementary ends, the ligase can join them together to form a single and intact DNA molecule, without interruptions. This is because the ligase enzyme seals the space between the molecules to form a single DNA fragment.  

The others enzymes have different functions:

DNA helicase is characterized by separating DNA from double strands into single strands and acts in DNA replication.

ATP methylase plays an important role in DNA replication when determining the beginning of replication that has already been replicated or not.

DNA polymerase is an enzyme that is responsible for catalyzing the polymerization of the new strand of DNA during the replication of this molecule.

miss Akunina [59]

Answer: The primary motor cortex for control of voluntary muscles is found in the precentral gyrus of the frontal lobes.

Explanations:

The primary motor cortex is one of the important brain areas involved in motor function. It is found in the precentral gyrus of frontal lobes. It control voluntary muscles and generate impulses needed for movement execution.

Voluntary muscles are muscles that we can control consciously or we can control them at will and we can choose when we want to use them. They are also refers to as skeletal muscles and are attached to bones. The are majorly use for locomotion.

Which of the following serves as an electron carrier in cellular respiration?
GrogVix [38]

Answer;

-NAD+

Explanation;

-When glucose breaks down into ATP, a large amount of the energy is stored as electron on special molecules (the electron carriers). When an empty electron carrier accepts a pair of electrons, it is reduced; when it gives those electrons up later on, it is oxidized.

-NAD+ and FAD; also the two most common electron carriers in the body. NAD+ can accept a pair of electrons (and a hydrogen ion) to become NADH.
