Answer:
A. putting smoke into air
Explanation:
Can't be B. because they are harming the water from dangerous chemicals. Not C. because they are harming the atmosphere from dangerous chemicals. Not D. because phospate is used in fertilisers and if that gets in water it will cause algae bloom a sudden growth in algae which will block light from coming in the river or lake and so hydrophytes(aquatic plants) will die and fish will not get any oxygen so will also die. The algae bloom creates toxic stuff because of competition and will make the river of lake dangerous to be in. We are only left with A. so that is the answer.
Answer:
Its D
Explanation:
Using detergents that put phosphates into water

How the respiratory membrane works. What cell types and what forces allow the diffusion of gases across the respiratory membrane?
Acc6ording to the question:
When we breath; there is air in and out though out from our lungs. How could it happen. Oxygen and carbon dioxide moves across the respiratory membrane. Normally the membrane separating air within the alveoli from the blood within pulmonary capillaries and consists of the alveolar wall, the capillary wall, and their basement membranes. Respiratory membrane is very thin, somehow its is approximate less than 0.5 mm. Explain?The respiratory membrane includes millions of alveoli with a surface area, the large respiratory surface area, combined with other factors, makes for efficient gas exchange to meet our metabolic needs.
Respiratory membrane allows gases to be exchanged between the pulmonary capillaries, or blood vessels, and the respiratory units of the lungs, which consist of bronchioles, alveolar ducts, atria and alveoli.
Since respiratory membrane is very thin,it consists of only two cells, one is the alveolar epithelial cell and the other is pulmonary capillary cell.Gas exchange occurs in the lungs between the air and our blood.

Cellular respiration and photosynthesis are similar in that both require a. carbon dioxide molecules b. energy-carrier molecules c. glucose molecules d. oxygen molecules
Cellular respiration and photosynthesis are similar in that both require energy-carrier molecules. The correct option is b.
What are energy-carrier molecules?The energy transport molecule found in cells in the highest concentration is adenosine 5'-triphosphate, or ATP.
Three phosphate groups, an adenine nitrogen base, and a ribose sugar make up this molecule. The compound adenine plus ribose sugar is referred known as adenosine.
During cellular respiration, glucose is produced using NADH and ATP. Both an enzyme and a channel protein, ATP synthase serves two functions.
ATP molecules include the carbon atoms from glucose after the conclusion of cellular respiration.
During the process of photosynthesis, two molecules that carry energy are actually present. NADPH and ATP are the two molecules that carry energy.
Thus, the correct option is B.

Digestive enzymes help to break down food in its simplest form. Pepsin is a digestive enzyme which leads to the degradation of proteins in the stomach. It is produced as pepsinogen and converted to active pepsin in the stomach by the removal of several amino acids.
What is pepsin?Pepsin is a digestive enzyme which is present mainly in the gastric juice in stomach and helps to breakdown protein into peptides.
This pepsin is present in the stomach in the form of inactive pepsinogen. This pepsinogen gets active in the stomach by the action of hydrochloric acid.
Pepsinogen gets active and forms pepsin.
Thus, it can be concluded that the digestive enzyme pepsin degrades protein in stomach and is synthesized as pepsinogen and gets converted into active pepsin in stomach by removal of several amino acids.

If red blood cells are placed in distilled water and examined under a microscope no cells are seen. Explain why no red blood cells would be seen.
Answer:
Explanation:
Distilled water has no contaminants and minerals thus the solute concentration inside the RBC is more than water. Water moves towards high solute concentration, therefore, water will go inside the RBC and burst it. This is why no RBC will be seen. You could see remanants of burst open and defective RBC but healthly RBC wont be there.

dierendy? they come back into contact with each other 1.000 years later, is it
made they could have become different species? Explain (Must be 6+ sentences)
Answer:
Yes, this is plenty of time for the humans in Mars to revolve differently. Due to Mars having different features (plants, air quality, etc) the people on Mars may develop differently to aid them in living on a different planet. They may develop a different variation of lungs to help them breathe better. Another possibility is a development that allows them to store water linger due to possible lack of water. In this span of time, humans on Mars may have begun developing these difference tools. As a result, in many years after the humans on Mars could almost be completely unrecognizable to the humans on Earth.
