Answer:
The human body is able to synthesize them: proteins, fats
Contains nitrogen in the amine group
: proteins
Made according to instructions from DNA: proteins
Explanation:
The cells of the human body synthesize proteins from the transcription and translation processes.
Fats and carbohidrates are ingested in the diet and metabolized by the body. However some types of fat such as cholesterol is synthesized by the human body. Same as phospholipids that are part of the membranes.
Proteins are formed by hydrogen, oxygen, nitrogen and carbon. Amino acids are characterized for owning a carboxyl group (-
COOH) and an amino group (-NH2)
Answer:
a The pulmonary artery carries deoxygenated blood.
Explanation:
This is the the only artery that transports deoxygented blood in mammals. specifically it carry deoxgenated blood from the the atria to the pulmonary circulation. That is to the lungs for the exchange of the C02 in the deoxygenated blood with oxygen in the lungs.
The blood thus become oxygenated,and therefore return through the pulmonary veins to the left ventricle.
From the left ventricle ,through ventricular systole,blood is empty into the aorta through the aortic valves into the systemic circulation.
Although,they carry blood away from the heart,but the blood is de oxygenated instead of the usual oxygenated by arteries,They are still regarded as arteries because of convey of blood away from the heart,a typical role of arteries
Ultraviolet light will increase on earth's surface. It will "raise" temperatures and decrease plant populations.
Actually UV rays do not increase temperature, that's wrong.
They cause mutations in several organisms as they modify their DNA. They also cause skin cancer in humans and also cataracts and sunburns.
But they don't increase temperature.
That's carbon dioxide accumulation.
There are many human activities that have aggravated the planet through the phenomena of global warming. However, the biggest contributor to global warming is human use of fossil fuels and the resulting emissions from this use. The use of automobiles, factories, and other fossil fuel burning activities have led to a dramatic increase in greenhouse gases in the atmosphere which has led to global warming.
