If a pair of homologous chromosomes fails to separate during anaphase of meiosis I, what will be the chromosome number of the four resulting gametes with respect to the normal haploid number (n)?

a) n + 1; n + 1; n - 1; n - 1

b) n + 1; n + 1; n; n

c) n + 1; n - 1; n; n

d) n + 1; n - 1; n - 1; n - 1

Answer:

a) n + 1; n + 1; n - 1; n - 1

Explanation:

Separation of homologous chromosomes occurs during anaphase-I of meiosis. This event reduces the chromosome number from 2n to "n" in the daughter cells. If a pair of homologous chromosomes do not separate during anaphase-I, both the homologous chromosomes of that pair would be present in one daughter cell of the meiosis-I (n+1) while the other daughter cell would lack that chromosome (n-1).

Meiosis-II would maintain this chromosome number. Therefore, two gametes will have one extra chromosome (n+1) while the two gametes would lack one chromosome (n-1).

How does the property of water pictured below help a plant to thrive?
gayaneshka [121]

The adhesion and cohesion property of the water helps a plant to thrive.

Explanation:

The adhesion and cohesion property of the water is the two most important properties of water that regulate how water will work at different places of a plant. When water gets attracted to water then we can call it cohesion.

When water gets attracted to other substances then we can call it adhesion. In different part of the plants like roots, stem and leaves water reaches there by capillary action and works differently based on adhesion and cohesion property

Roman55 [17]

The correct answer is option A- HIV virus.

HIV virus is an example of enveloped virus, that has the ability to infect a host cell by attaching itself to it and fusing with the host cell. Once infected, the virus leaves the host cell and moves to another cells to infect them. The HIV virus contains glycoprotein spikes to attach to the host cell.
