Explanation:
Hormones can travel through the blood and not affect all tissues; only cells possessing<u> receptor</u> sites for that particular hormone are affected, and these cells are called <u>target</u> cells.
The endocrine system involves chemical signalling via the secretion of molecules called hormones into extracellular fluid. They bind to chemical receptors in order to cause specific changes in target cells, these lead to changes in the body's internal environment called homeostasis.
Further Explanation:
During homeostasis the body maintains a constant internal balance in pH, temperature, blood pressure etc. Cells in a multicellular organism become specialized for particular tasks and communicate with one another in order to maintain homeostasis.
Within the human body these are known as hormone cascades, where several complex steps occur- the tissues signal to one another with the use of hormones released by the endocrine system. The regulation (increase and decrease) of these secretions is achieved by negative feedback loops, where the release of certain substances during a cascade in turn halts the secretion of hormones at earlier stages.
The endocrine system includes the thyroid, parathyroid, pituitary, pineal and adrenal glands along with other regions. The bone, adipose tissue, heart, pancreas and liver are a few of the regions of the body which show endocrine function. The brain, or control center functions to receive and process the information from the receptor. Effectors receive the control center's command and illicits a response in the form of a feedback loop, that may oppose or enhance the stimulus.

Peanut Butter is a very attempting choice, but I'll have to mark it out.
Plants absorb nitrate mostly to be able to produce "B. Amino acids, proteins, and nucleotides."
They need these so they can expand roots, be able to take in water, successfully complete photosynthesis so they can make their own food. Basically they need these things to survive.
I really hope this helped!!

This is an example of Homeostasis or Adaptation.
Suicide is the obvious answer.
↪Cancer :It doesn't seem to be related with depression as a causing agent. But cancer can cause depression.
↪Parkinson's disease: Less common in women than in men. So it can't be leading cause of the death.
↪Cardiovascular disease: Actually it depends upon the lifestyle of person. If you are exercising , doing yoga and any physical activity ,you have less chance of this disease. Depression can be one of its causing factor but not the major factor.
Answer:
Option C, epiglottis
Explanation:
Epiglottis is a flap structure located at the larynx opening which is a separator between the upper and lower respiratory tract.
The upper part of the respiratory tract consists of Nostrils, Nasal Cavities, Pharynx, Epiglottis, and the Larynx.
After the Larynx, the upper respiratory tracts connects the trachea from where the lower respiratory tract starts. The lower respiratory tract consists of Trachea, Bronchi, Bronchioles, and the Lungs.
Hence, option C is the correct.
