Answer:
B. A precipitin test is the correct answer
Explanation:
To determine whether a bloodstain is of human or animal origin, the serologist will perform: A precipitin test.
The precipitin test is based on the interaction between antigen and antibody which results in the formation of antigen-antibody complexes and this visible precipitate antigen-antibody complexes is called precipitin.
Precipitin test is a serological test where antibody reacts with soluble antigen to produce a precipitate.
The precipitin test is used to distinguished whether the blood sample is from human or different sources.
Answer- A: Air conditioning
Explanation-
Florida is usually very muggy, hot, and humid in the summer, this causes buildings to increasingly get warmer minute by minute because they didn’t have air conditioning. Also factories themself are warm due to the machines and all the people inside. But, once the air conditioning came around, this caused an easier environment to work in.
The most accurate example of a primary endocrine pathology in the pathway controlling cortisol secretion is Dysfunction in the adrenal cortex.
When the adrenal glands don't generate enough cortisol and occasionally aldosterone, it is called adrenal insufficiency. When the glands' outer layer, the adrenal cortex, is destroyed, the production falls. When you have an autoimmune condition that causes your body to attack the glands, this most frequently happens. Tumors, TB, and other diseases are also potential causes. Primary adrenal insufficiency is the name given to this condition.
A lack of adrenocorticotropin (ACTH), a hormone generated by the pituitary gland, results in secondary adrenal insufficiency, which is more frequent than the primary variety. Your adrenal glands won't produce enough cortisol if your pituitary doesn't produce enough ACTH.
