Answer:

(A). Sexual reproduction increases genetic diversity, and asexual reproduction can be more rapid.

Explanation:

Sexual reproduction is a mode of reproduction, which involves formation of new organisms by combination of genetic information from two organisms of different sexes. The major advantage of sexual reproduction is to develop genetic diversity as new organism is produced by mixing up genetic material of both the parents.

On the other hand, asexual reproduction involves formation of new organisms from a single parent having identical genetic makeup as present in parent cell. One of the major advantage of asexual reproduction is to produce high number of offspring in less time as it is more rapid than sexual reproduction.

Thus, the correct answer is option (A).

Answer:

Option C

Explanation:

Given ,

A1 allele is carried by $70$ % people

Let us assume A1 s dominant genotype

This means $p= \frac{70}{100} = 0.7$

Thus, frequency of allele in the given population is $0.7$

It is also given that the population is in Hardy-Weinberg equilibrium thus

$p+q=1\\0.7+q=1\\q = 1-0.7\\q= 0.3$

Frequency of fruit fly with genotype A2A2 will be

$q^2\\= (0.3)^2\\= 0.09$

As per Hardy-Weinberg's second equation of equilibrium

$p^{2} + q^{2} + 2pq = 1\\0.49+0.09+2pq = 1\\2pq = 1-0.49-0.09\\2pq= 0.42$

Hence, option C is correct

A nerve impulse is an electric charge running across a neuron. Explain why the stimulation supports this explanation

Softa [21]

Plato answer:

Stimulation of a neuron causes a change in the charge inside the cell from negative to positive. This change is caused by ions, which are atoms with an electrical charge, moving across the cell. This change within the cell is consistent with the definition of an electric charge.
