Answer:
Option-C
Explanation:
The M phase of the cell cycle proceeds in the four phases: prophase followed by metaphase then anaphase, and telophase.
These sub-phases can be easily distinguished as the genetic material move in the cell in various form and the changes become characteristic of the subphases.
During metaphase, the chromosomes are aligned at the center of the cell or at the imaginary equatorial plate. Since it is mentioned that the drug shows its effect when the chromosomes are aligned at the equatorial plate therefore he is referring to the metaphase of the cycle.
Thus, metaphase is correct.

The hormones which cause Jane’s problem are the thyroid hormones.
The condition is hypothyroidism
Explanation:
Condition: Hypothyroidism is an endocrine disorder which arises when the thyroid gland cannot produce the necessary amount of thyroid hormones like thyroxine (T4) and triiodothyronine (T3).
Both T3 and T4 are tyrosine-based hormones which regulate metabolism and any deficiency slows down the metabolic processes and can result in high cholesterol levels and atherosclerosis
Causes: An underactive thyroid gland and Autoimmune disorder
Diagnosis: Thyroid function tests by measuring serum thyroid stimulating hormone (TSH) and T4 levels
In hypothyroidism, the TSH secreted by the pituitary gland will be high because it is producing more hormones to stimulate the underactive thyroid gland.
An underactive thyroid gland cannot produce normal levels of T4 in the body.
Symptoms: Fatigue and weakness, cold intolerance, weight gain and puffy appearance, hair thinning, dry skin, decreased concentration, poor memory, muscle and body aches etc.
Treatment
: Hormone replacement therapy with levothyroxine
Answer:
16 genetically different offspring
Explanation:
This is the case as each parent has the ability to produce 4 uniquely different gametes through independent assortment. With such a scenario where each parent can product 4 uniquely different gametes multiplied by 4 parents, you have 16 offspring. So there's the possibility of producing 16 offspring that are unique.
