Bird species from temperate regions must cope with relatively short breeding seasons. A study examined the relationship between

blood testosterone level (ng/ml) and the duration of the egg-laying period (months) in temperate bird species.

With regard to the functioning of the thyroid gland, which is an essential element for the manufacturing of thyroxine and triiod
Vikki [24]

Answer:

The correct answer is- iodine

Explanation:

Thyroid glands is an important endocrine gland of the body which release hormone called thyroid hormone in the blood. It plays an important role in metabolism, brain development, and function, muscle control, etc.

The active form of thyroxine is triiodothyronine and the formation of thyroid hormone requires the availability of iodine. Four iodine atoms are present in thyroxine and 3 is present in triiodothyronine. Without iodine, they can not be produced.  

Therefore iodine is the essential element that is required for the manufacturing of thyroxine and triiodothyronine.

Amanda [17]

Answer:

See the complete question and the answer below

Explanation:

<em>Suppose that you and a friend see brightly colored pigeons like these at a nature park. Because pigeons are usually gray and white, you both wonder where these colors came from. Suddenly, your friend says, "I have a theory. These birds must get their colors from eating food that has the same colors."Is your friend's explanation a scientific theory? Give reasons to explain your answer</em>

<em>The answer is </em><em>no</em><em>. My friend's explanation is not a scientific theory.</em>

A scientific theory is a tested and proven phenomenon. In order for a statement to become a theory, it must have been tested through experimentation by several independent researchers and found to be true. A mere statement based on perception with little or no experimental test is just a hypothesis and not a theory.

Instead of my friend to have said, "I have a theory", he should have said, "I have a hypothesis".
