The two major systems involved in the stress response are the Nervous System [the Sympathetic subdivision of the Autonomic Nervous System (ANS)] and the Endocrine System (glands which secrete hormones intonthe bloodstream).
The Endocrine System's response during acute and/or chronic stress (adaptation) involves first the Hypothalamic release of Corticotropin-Releasing Hormone (CRH), which stimulates the Anterior Pituitary (via the blood) to release AdrenoCorticoTropic Hormone (ACTH), which then activates the Adrenal Cortex to release glucocorticoid hormones (i.e. Cortisol), amongst others into the bloodstream. Cortisol then has many effects on tissues and organs throughout the body to allow better generalized coping with the initial stress stimulus.
Answer:
Proteins.
Explanation:
Protein is one of the most important biomolecule of the living organisms. Proteins are made up of the polymers of the amino acids. These are the primary building block of the body.
Proteins are involved in the assembly of different molecules. Proteins are involved in the immune response initiation, the enzymatic activity and the cell signalling of the molecules.
Thus, the correct answer is option (B).
Answer: A plants cell as one large vacuole, while a animal cell has 1+ small vacuole
Explanation:
C)temperature and rainfall
Explanation:
Temperature and rainfall are the most important physical factors that shapes the characteristics of an ecosystem.
Temperature is the degree of hotness or coldness of a place. It is mostly as a result of the solar radiation it receives.
Rainfall is a form of precipitation in which water falls under gravity in liquid form.
They are both by far the most important factors that shapes ecosystems.
