<span>Cells are living units, surrounded by a membrane, with or without nucleus (this is also the majo division of cell types). Cells can live "on their own", if certain conditions are fullfilled. Viruses live inside (some) cells and they are dependent on those cells on survival</span>
High levels of cortisol would normally provide negative feedback to the D)the anterior pituitary and the hypothalamus.
ACTH secretion stimulates the discharge of glucocorticoids (cortisol), mineralocorticoids (aldosterone), and androgen from the adrenal cortex.
Corticotropin-liberating hormone (CRH) is launched from the hypothalamus, which stimulates the anterior pituitary to release adrenocorticotropic hormone (ACTH). ACTH then acts on its target organ, the adrenal cortex.
Cortisol increases blood sugar by way of releasing stored glucose, at the same time as insulin lowers blood sugar. Having chronically high cortisol stages can result in continual high blood sugar (hyperglycemia). this can purpose type 2 diabetes.

Vectorborne transmission of an infectious organism occurs via <u>animals or insects. </u>
Vectors are living organisms that can transfer an infectious disease from infected animals to humans. These species are known as arthropods. It includes mosquitoes, ticks, triatomine bugs, sandflies, etc.
There are two types of vectors; Biological and mechanical.
Biological vectors such as mosquitos transmit the disease by biting the host body. Mechanical vectors on the other hand cause infectious disease just by physical contact.
Arthropod vectors are cold-blooded. The diseases that are transmitted by them are known as vector-borne diseases. Malaria and Dengue are examples of vector-borne diseases.

Answer:
b. become part of the body's structural systems.
Explanation:
- Minerals are the inorganic regulators needed for different functions inside the body.
- Minerals donot provide energy but involved in generation of energ through their metabolic function. (Hence option A is excluded)
- They provide a good medium for the protoplasmic activities (permeability of cell membrane and normal functioning of cell)
- Maintaining bod fluid balance.
- For structural units.
- Cannot be degraded in the body neither can be destroyed while cooking ( Hence option c and d are excluded)
- They become the part of the body's strctral systems (Hence option B is the right answer)
