In most sexually reproducing organisms, the diploid phase of the life cycle begins at
valkas [14]

The diploid phase of the life cycle begins with the formation of the zygote.

Meiosis is referred to the type of cell division which occurs in the production

of male and female sex cells. This also occurs during sexual reproduction.

Parent cells provide male and sex cells such as sperm and egg which

contains DNA. They then fuse together to form a zygote which is the diploid

phase as a result of the fusion of two haploid cells. The zygote then

continues to undergo some meiotic processes which reduces it to back to a

haploid cell and consequent growth to form a fetus.

andrew-mc [135]

Answer:

d. Measure thyroid-stimulating hormone level

Explanation:

The most suitable next step in management of this patient is to measure a thyroid stimulating hormone, or thyrotropin level.

This patient's apparent treatment refractory dyslipidemia is most likely contributed by undiagnosed thyroid disease. Despite sticking to the treatment with atorvastatin, his  LDL AND total cholesterol are raised.

Additionally, there are some clinical signals that give an idea about the diagnosis of hypothyroidism especially  fatigue and constipation.

Hypothyroidism is concerned with and is a very common secondary cause of dyslipidemia and thyrotropin level measures are indicated.

Hyperlipidemia may show better results to thyroid stimulating hormone.

Hence option D is the right answer.
