PLEASE HELP ILL GIVE BRAINLIEST

Biology
1 answer:
Finger [1]2 years ago
8 0

Answer:

Purpose: Meiosis is a special version of cell division that occurs only in the testes and ovaries; the organs that produce the male and female reproductive cells; the sperm and eggs. ... Therefore the purpose of meiosis is to produce gametes, the sperm, and eggs, with half of the genetic complement of the parent cells.

Genetic variability is a measure of the tendency of individual genotypes in a population to vary (become different) from one another. Variability is different from genetic diversity, which is the amount of variation seen in a particular population.

Meiosis generates genetic diversity through a process called crossing over which allows new combinations of variations to appear in gene pool. ... Chiasmatal points appear randomly on homologous chromosomes, hence amount of genetic material exchanged in every case/cell could be different.

Maru [420]

Answer:

In a particular case of secondary succession, three species of wild grass all invaded a field. By the second season, a single species dominated the field and the other two species had a lower relative abundance. A possible factor contributing to the abundances of these species in this example of secondary succession is <u>inhibition</u>.

Explanation:

Trees are great examples of allelopathy in plants. Some use their allelochemicals to inhibit germination or impede development of nearby plant life. Most allelopathic trees release these chemicals through their leaves, which are toxic once absorbed by other plants. Black walnut is a prime example of this.

The respiratory rate times the tidal volume corrected for the dead air space in the lungs is the __________.
pav-90 [236]

Answer:

d. alveolar ventilation rate

Explanation:

Alveolar Ventilation rate (AVR) refers to the rate of airflow that reaches the alveoli which is available for gas exchange with the blood in a given unit of time. AVR is generally calculated as the amount in millimeters of air expired that equilibrates (i.e., exchanges) with alveolar gas per min unit (ml/min). AVR is affected by breathing frequency, tidal volume ( i.e., the normal amount of air between inhalation and exhalation), and the amount of dead space in the lungs.
