Answer: an increase in the human population

Explanation:

An increase in the human population is the likely cause of the current increase in rates of extinction because of the fact that the human population is increasing considerably all over the world. With the increase in population the demand for resources also increasing. The human population is dependent upon flora and faunal species for their daily requirements such as medicines, food, cloth and shelter. Illegitimate activities like hunting, poaching, wildlife trafficking also increasing considerable and are responsible for extinction of the rare species from the world biodiversity.

In plants tall (T) is dominant to short (t) and round seed is dominant to wrinkled seeds (r). If a parent is short and wrinkled

Nuetrik [128]

Answer:

Parent cross= ttrr (short, wrinkled) × TtRr (hybrid)

POSSIBLE GAMETES BY EACH PARENT:

ttrr - tr, tr, tr, and tr

TtRr - TR, Tr, tR, and tr

Explanation:

This question involves two genes in a certain plant. One gene is coding for height while the other is coding for seed shape. The alleles for tallness (T) and round seeds (R) is dominant over the alleles for shortness (t) and wrinkled seeds (r).

According to this question, a parent that is short and wrinkled (ttrr) is crossed with another parent that is hybrid (TtRr) for both traits. This means that the parent cross is as follows: ttrr × TtRr

The possible combination of gametes that will be produced by each parent is as follows:

ttrr - tr, tr, tr, and tr

TtRr - TR, Tr, tR, and tr

See attached image for the punnet square using these gametes.

Hair texture in humans is an example of incomplete dominance. If a man with curly hair has children with a woman with straight h

Damm [24]

Answer:

100% Wavy hair

Explanation:

The gene involved here codes for hair texture in humans. The alleles of the gene (straight, S and curly, s) exhibits incomplete dominance. Incomplete dominance is a genetic scenario whereby one allele does not completely mask the expression of the other allele, instead an intermediate phenotype that is heterozygous is formed.

In this case, a man with curly hair (ss) marries a woman with straight hair (SS). The children from this cross will all possess a heterozygous genotype (Ss) and be phenotypically wavy-haired, since Incomplete dominance is exhibited by the gene. Therefore, 100% of the offsprings/children will have wavy hair phenotype.

-Chemical synapse are the most numerous type of synapse in the human body
-chemical synapse are unidirectional

Chemical synapse are specialized junction by which cells of the nervous system signal to one another and also to non neuronal cells such as muscles and glands. This also allows the neurons of the central nervous system to form interconnected neural circuits. They are crucial to biological computations and provide means to connect and control other systems in the body.
