Amanda hates her new student ID photo. Her hair looks dry, the extra weight she's gained shows, and her neck looks fat. Amanda's also been feeling very tired and mentally dull. Amanda goes to the clinic where you are working. You draw her blood. The test results show her T4 levels are low and her TSH levels are low. Later she is given a TSH stimulation test in which TSH is injected and the T4 levels are monitored. After TSH injection her 14 levels rise. A) Does Amanda have problems with her pituitary or with her thyroid gland? B) How did you come to your conclusion?

A) Pituitary Gland B)By analysing the given observations in the question.

Explanation:

THS, thyroid stimulating hormone, is an hormone produced by the pituitary gland and in return it stimulates the thyroid gland that produces hormones such as T3 and T4.

We can conclude from the given information that Amanda's thyroid gland does not have a problem with producing and secreting the T3 and T4 hormones when THS is present in her body.

But the low THS levels show that the problem is with her pituitary gland causing her to have low levels of THS.

We can reach this decision by analysing the given information.

I hope this answer helps.

the wetland preservation movement began in the u.s. in earnest with the clean water act (cwa) of 1972. although not specifically written to protect wetlands, the cwa is comprised of a series of regulations designed to prevent pollutants from contaminating u.s. waters.

answer;

c. a tree whose roots are surrounded by wet sand.

explanation;

water stress is an important factor limiting the growth and productivity of forests.water stress is the most often cited cause of poor survival and growth of woody landscape plants.

-insufficient soil moisture is the most common form of water stress, but excess moisture that leads to poor soil aeration (hypoxia) can also result in reduced plant vitality. a tree whose roots are surrounded by wet sand would be least likely to experience water stress.
