Answer:

The correct answer is - one pair of sex chromosomes and 22 pairs of autosomal chromosomes.

Explanation:

A karyotype is a test to recognize and analyze the shape, size, and numbers of chromosomes in a cell present in sample collected from humans or another organism.

The normal karyotypes of humans consist of 22 pairs of autosomal chromosomes and a single pair of sex chromosomes also known as allosomes. In males, the allosomes are XY where is in females both allosomes are XX.

Thus, the correct answer is - one pair of sex chromosomes and 22 pairs of autosomal chromosomes.

What element is necessary for the production of thyroid hormone?
liubo4ka [24]

Answer:

Iodine

Explanation:

This is a trace element needed for the  synthesis of the two thyroid hormone ; T4- thyroxine and T3-triiodothyronine. Four iodine molecules are added in T4 synthesis, and  three for T3 synthesis. Generally T4 is the major hormone produced, but  biologically transformed into active form T3.

Iodine majorly and selenium are the two trace elements needed for thyroid hormones synthesis. Therefore required amount of iodine is important in daily diet. iIn adequate supply of this leads to under production of iodine called hypothyroidism. poor brain development ( especially in kids),and goiter.

Sea foods . eggs, poultry seaweeds are rich sources of iodine.

Conversely, when  excessive amount is present in the blood, autoimmune thyroid diseases can occur,including cancer developments in the thyroid gland due to hyper cell activities.
