The question is incomplete. The complete question is:
"In Graves disease, thyroid-stimulating immunoglobulins (TSI) contain an active site that can mimic the active site of TSH to stimulate thyroid hormone production. One would expect TSI to cause:"
A. An increase in thyroid gland size because of the trophic effect of TSH.
B. A decrease in thyroid gland size because of competitive inhibition with TSH.
C. No change in thyroid gland size because antibodies only recognize foreign particles.
D. An immune response against TSH molecules.
Answer:
A. An increase in thyroid gland size because of the trophic effect of TSH.
Explanation:
Thyroid-stimulating hormone is a trophic hormone and is released by the anterior pituitary gland. It targets the thyroid gland and stimulates it to release the thyroid hormones. Graves disease is an autoimmune disorder in which the person produces antibodies such as thyroid-stimulating immunoglobulins that mimic the action of thyroid-stimulating hormone (TSH).
These antibodies continually stimulate the thyroid gland to grow and produce thyroid hormones. The result is an abnormally enlarged thyroid gland. The affected individuals also develop peculiar edema behind the eyes that causes the eyes to protrude.
Answer: Option B) Photosynthesis
Explanation:
It is impossible for plants to release energy from glucose using photosynthesis because photosynthesis results in the formation of sugar molecules such as glucose.
6CO2 + 6H2O --> C6H12O6 + 6O2 + Energy
From the equation, photosynthesis is seen to as a biosynthethic reaction not a catabolic one.
Thus, it produces energy-rich compounds like glucose not otherwise
More on space than on earth
Answer:
1. If decomposers were removed then most animal carcasses and any other dead organic material would be dormant.
2. If top predators were killed off, that predators preys population would spiral out of contorol and take up many other resources.
3. Everything that feed off of grasses and whatever feed of them and whatever would feed of them would die. So in short words that ecosystem would collapse.
