Answer:

Oocyte refers to the female germ cell which is involved in the process of reproduction.

In humans, the primary oocyte is diploid in nature, that is, it contains 46 chromosomes as it is formed by mitotic divisions of the oogonium.

In contrast, secondary oocyte is haploid in nature, that is, it contains only 23 chromosomes as it is formed from primary oocyte after it has completed its meiosis I.

Secondary oocyte then undergoes meiosis II to produce a mature ovum.

Identify one way in which the process of growth of a human embryo is similar to the process of reproduction in a single called o

iragen [17]

Answer:

The correct answer would be mitosis and binary fission.

The human embryo grows through the process of mitotic divisions through a parent cell divides into two equal sized daughter cells each of which contains identical genetic material.

Similarly, single-celled organisms reproduce asexually through the process of binary fission during a parent cell divides into two equal sized daughter cells each of which contains identical genetic material. Each daughter cell grows and matures to become an independent adult.

Which situation would most likely increase the carrying capacity for humans

vredina [299]

C. A new source of freshwater

Explanation:

The situation that would most likely increase the carrying capacity for humans in a certain region is the availability of new sources of freshwater.

In ecological terms, the carrying capacity of a place is the the number of people, animals, or crops which a region can support without environmental degradation.

A new source of freshwater provides new resources for the ecosystem.
In the freshwater, more fishes are available, more plants can grow around and a lot of biological activities can progress.
Water is essential for life.
Fresh water sources are incentives for choosing to live in a place or not.
A fresh water source increases the carrying capacity for humans in a certain region.

what does the term 2pq represent in the hardy-weinberg equation? the frequency of homozygous recessive individuals the frequency

Nostrana [21]

The term 2pq represented in the hardy-weinberg equation is the frequency of heterozygotes and is denoted as option D.

<h3>What is Hardy-weinberg equation?</h3>

This mathematical equation is used to calculate the genetic variation of a population at equilibrium and can be seen below:

p² + 2pq + q² = 1

where

p² is dominant homozygous frequency (AA)

2pq is heterozygous frequency (Aa)

q² is recessive homozygous frequency (aa).

The 2pq can be seen as the heterozygous frequency which is therefore the reason why option D which is frequency of heterozygotes was chosen as the most appropriate choice.
