Answer:
An autoimmune problem involving the thyroid gland: C. Graves' disease
Hyposecretion of growth hormone: Pituitary dwarfism
Hyposecretion of the pancreas: E. Diabetes mellitus
Hyposecretion of the adrenal cortex: B. Addison's disease
Hypersecretion of growth hormone: A. Acromegaly
Explanation:
Growth hormone is the hormone from the anterior pituitary gland that targets the tissues such as muscles, bones, cartilage, liver, etc. and stimulates the somatic growth of the body. Its hypersecretion leads to acromegaly in adults while its hyposecretion causes dwarfism in children characterized by stunted growth. There is abnormal thickening of specific bones in acromegaly.
Pancreatic hormone insulin serves to lower down the blood glucose levels. Insulin deficiency causes diabetes mellitus characterized by higher blood glucose levels in the affected person.
Hyposecretion of glucocorticoids and mineralocorticoid from adrenal cortex causes Addison's disease characterized by rapid weight loss, lower levels of glucose and sodium in plasma while a rise in potassium levels.
Grave's disease is an autoimmune disease wherein the thyroid gland is stimulated for increased secretion of thyroxine resulting in protruded eyeballs.
Answer:
Knowing the evolutionary relationships among species allows scientists to choose appropriate organisms for the study of diseases, such as HIV. Scientists are even using the principles of natural selection to identify new drugs for detecting and treating diseases such as cancer. Environmental change and isolation of groups of organisms play an important role in evolution. Environmental change is any change in an environment to which an organism must adapt. Change can be gradual, such as when mountains or deserts form, other species die out, or new species evolve.
Explanation:
<span>c ribosomes. lots and lots of ribosomes. Thousands of these protein forming organells and in the cytoplasm. When they are on the ER it is called rough ER (because of its sandpaper like appearence). Rough ER makes proteins either for inside the cell (to another organell) or outside the cell. If the ER does not have ribosomes, it is smooth ER. Smooth ER makes lipidds and steroids.</span>
