Answer:
Since the origin of humans on this planet, they have been trying their best to make their lives easier on this planet. In doing so, human activities have some how heavily damaged the Earth. Many day to day activities of humans are dangerous for the Earth.
Some of the consequences of human activities on the Earth's fresh water are :
Extinction of many aquatic species:
The water consumed by humans comes from the fresh water oceans. As the population of humans is increasing enormously, the water from the oceans is being consumed at dangerous levels. This has caused many species of aquatic animals to become extinct or to be at a verge of extinction as they do not have a habitat to survive or reproduce.
Pollution:
Many heavy industries, house sewage, farmers dispose waste into the fresh water. Hence, killing aquatic animals and polluting the fresh water ecosystems.
Answer: Serum thyroid-stimulating hormone test would confirm secondary hypothyroidism.
Explanation:
The serum thyroid stimulating hormone (TSH) test involves the intravenous administration of a small amount of Thyroid Releasing Hormone (TRH) and the measurement of TSH levels at some points following the administration.
The first step involves collecting the blood sample of the patient and measuring the baseline TSH prior to the intravenous administration of TRH. Blood sample is drawn again 30 minutes after TRH administration, and TSH level is measured and compared to the baseline measurement.
If there is slight or no increase in serum TSH level following TRH administration, it is secondary hypothyroidism because the cause of the hypothyroidism is in the anterior pituitary gland. This means that the pituitary gland is not secreting TSH because it is diseased.
