The kidneys are the organs responsible for filtering the body from excess materials like salts and other by-products that can be found from ingesting food and medicines. Without the functions of the kidneys the body will get poisoned because it can't process such waste and bring it to the excretory system in the form of urine and feces.
The dialysis machine acts out as kidneys in the body, when it is attached, blood is transfused into the machine and the machine filters the blood. As this happens, the blood is then returned to body clean and free from toxins.
Jane is a researcher who studies
the individual and collective aging processes in humans. Jane works in the
field of gerontology. Gerontology is the extensive study of aging processes in
humans as they age. Under gerontology, the physical, mental, and social changes
in older people is studied as they grow.
Answer: D
Explanation:
photosynthesis - takes in water, energy from the sun, and carbon dioxide and releases oxygen and glucose (sugar)
respiration - takes in glucose and oxygen, and releases water and carbon dioxide and energy
they are basically the opposite
HAVE A GREAT DAY :)
Answer:
global glacier mass
Explanation:
<em>The shrink or reduction in the volume of the global glacier mass is one of the evidence of global warming.</em>
<u>By definition, global warming is the rise in global temperature associated with increase in the concentration of greenhouse gases such as carbon dioxide, methane, nitrogen, etc.</u>
The gases naturally form a blanket layer over the earth's atmosphere and are responsible for preventing some of the sun's reflected radiation after reaching the earth from returning back to space. They absorb some of the radiations and warms up the planet in the process.
An increase in the concentration of these gases means that more radiation is absorbed from the sun, thus causing an increase in the amount to warming the earth gets. This increase in the amount of warming is what is termed global warming.
One known consequence of the increase in global temperature as a result of global warming is the melting of glacier mass. Glaciers are prone to melting with increase in temperature and the water derived from such melting are discharged into seas and oceans, causing a rise in their levels.
The secretion of human growth hormones (HGH) is regulated at the genome level by genetic and epigenetic factors (environment and diet among others). And the expression of the gene of this hormone differs from one individual to another, so the quantity produced differs between individuals, which explains why we observe individuals of different sizes in a population.
Growth hormone acts by interaction with cellular receptors, it affects carbohydrate, lipid and protein metabolism.
A key component of growth is the growth hormone releasing factor or the growth regulating factor (GH-RF or GRF). This chemical messenger is produced in a part of the brain called the hypothalamus. GH-RF allows the pituitary gland (the "master gland" involved in the growth process) to secrete growth hormone, the main hormone responsible for a person's growth.
GH is not only involved in growth phenomena, it also plays a role in the fine regulation of reproductive phenomena in both male and female mammals.
