Answer:
The steps in the production of thyroid hormone in the order in which they occur is: 1, 2, 4, 5, 3.
Explanation:
The thyroid gland is an organ located anterior to the trachea and inferior to the larynx. The tissue of the thyroid gland is composed of thyroid follicles, which are made up of a central cavity filled with a sticky fluid called colloid. The colloid is surrounded by a wall of epithelial follicle cells and it is the center of thyroid hormone production. The process of thyroid hormone production is dependent on iodine.
The following steps outline the processes involved in thyroid hormone production:
- The thyroid-stimulating hormone (TSH) binds to its receptor in the follicle cells of the thyroid gland, which causes the cells to actively transport iodide ions across their cell membrane, from the bloodstream into the cytosol. making the concentration of iodide ions in the follicular cells higher than that in the bloodstream.
- Iodide ions move to the lumen of the follicular cells that border the colloid. Thereafter, the ions undergo oxidation, which means that their negative charge is removed. The oxidation of two iodide ions results in iodine, which passes through the follicle cell membrane into the colloid.
- In the colloid, peroxidase enzymes link the iodine to tyrosine in thyroglobulin to produce two intermediates: a tyrosine attached to one iodine and a tyrosine attached to two iodines.
- When a tyrosine attached to one iodine is linked by covalent bonds to a tyrosine attached to two iodines, the resulting compound is a triiodothyronine (T3) which is a thyroid hormone with three iodines. When two tyrosines attached to two iodines are covalently bonded, they form a tetraiodothyronine, also known as thyroxine (T4) a thyrroid hormone with four iodines
- These hormones remain in the colloid center of the thyroid follicles until TSH stimulates endocytosis of colloid back into the follicular cells, where the hormones are then stored.
France didn't control any land after 1763
The Northwest Ordinance was enacted on July 13, 1787. It created the Northwest Territory, which was the first organized territory of the United States.
The Ordinance set the basis for the government of the Northwest Territory as well as the admission politics of its constituent parts and states.
According to this ordinance, each district was to be governed by a governor and judges appointed by Congress. Then, if the district attained a population of 5,000 adult free males, it would be recognized as a territory and it would be able to form its own representative legislature.
Finally, until the Norwest Territory had incorporated a minimum of three and a maximum of five states, if an individual territory attained a population of 60,000, it could be admitted to statehood in the union.
So, the correct answer is A: Only territories with a population of at least 60,000 could apply for statehood.

I think its autonomous morality.
since he is making his own conclusion as to why its okay to take the purse.
Answer:Epigenetics theory
Explanation:
Epigenetics studies changes that are inherited through gene expression without an alteration to the DNA sequence. This means changes in phenotypes but no changes in genotypes, epigenetic occurs naturally but can also be affected by age, environment and diseases.
