Answer:
If during meiosis the efficiency to form tetrads is reduced or absent -due to a mutation- this defect would most likely affect the ability to align homologous chromosome at the metaphase plate.
Explanation:
Options for this question are:
<em>a) Breakdown the nuclear membrane
</em>
<em>b) Duplicate centrosomes
</em>
<em>c) Assemble spindle microtubules
</em>
<em>d) Establish spindle poles
</em>
<em>e) Align homologous chromosome at the metaphase plate</em>
During the zigoteno of the prophase I (meiosis) the bivalent chromosomes are formed, product of the pairing of genes. Each of the chromosomes of a pair is constituted by two sister chromatids, resulting in a structure called tetrad, due to the existence of four chromatids.
If in the next phase, metaphase, tetrad (four chromatides) has not formed, alignment in the equator and spindle synthesis is not possible, so the metaphase plate is not formed and the respective chromosomes cannot migrate to cell poles.

Answer:
Resolution
Explanation:
There are four stages of sexual response cycle :
<u>1) Excitement (Desire)</u> : Beginning of sexual arousal , preparation of intercourse.
<u>2) Plateau (Arousal)</u> : Physical arousal builds
<u>3) Orgasm</u> : Males ejaculate while females experience vaginal contractions
<u>4) Resolution</u>: It is the stage of sexual response cycle in which
- Arousal slowly subsides and returns to normal levels
- Males experiece a refractory period during which they are incapable of having another erection of orgasm
- Blood is leaving the genitals, the erection subsides, muscles relax, and breathing and heart rate return to normal
Hence the stage mentioned in the scenario is the resolution stage of sexual response cycle.
