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.
The change of temperature lava cools down/seconds it flows down.
Answer:
This used use to transfer heat which is dissipated from the body. it is the heat needed to stabilize the body temperature for the cells and tissues to do some biological work.It is also from the heat that enzymes maintain there activity.

Answer:
I'd say C, The main different between cellulose, and starch is the function they preform in plants.
Explanation:
I've done some research to find that starch and cellulose do compose of different parts of the plant, and that starch repeats glucose units oriented in the same direction, while cellulose repeats glucose units 180° around the axis of the polymer backbone chain. Of course we know photosynthesis produces glucose, and oxygen from co2, light energy, and h20. Which means that they both have the same monomer. Since cellulose and starch are polymers of the monomer glucose, A can't be right. They are said to have the same size because the only difference is how the repeat of the glucose monomers are oriented differently so this does not exactly change its relative size, so B can't be right. Starch has alpha linkages while Cellulose has beta linkages. This means they have a different structure which can affect the function. Also, the function of cellulose is a Structural polysaccharide(cause it is part of the walls of the plant), while starch is a Storage polysaccharide (cause sugar=energy).
