Answer:
Hello. You did not enter the answer options, but the factor that most directly influences a measurable result in an experiment is the manipulation of the variables.
Explanation:
In an experiment, the manipulation of variables becomes highly important so that it is possible to measure, that is, evaluate the result. This is because it is the variables that express values that represent the characteristics that are being analyzed and studied within the experiment. Therefore, the manipulation between them must be done in a very rational and balanced way so as not to modify the values shown by them, changing the data and generating false or immeasurable data.

Answer:population can affect the level of oxygen in water because of the too much of oxygen being released
Explanation:
Answer:
A. Their bodies tend to take in too much water.
Explanation:
Osmoregulation is the maintenance of osmotic concentration inside the body cells and in the extracellular fluid by controlling the amount of water and salts. Organisms living in water can be divided into two groups: Some are osmoconformers which change the osmolarity of body fluids with respect to the surrounding medium. Some are osmoregulators which do not allow change in internal osmolarity and try to maintain it by various means.
If as osmoregulator is placed in fresh water environment then their body is hypertonic to their environment. Osmosis will occur which is the movement of water from low solute to high solute concentration. Thus the problems faced by such organisms would be:
- Entry of excess water
- Loss of body salts to outside.
Adaptations in such organisms would be:
- Body cover such as scales or adipose covers
- They do not drink more water
- Excess water is eliminated as dilute urine
- Special cells called ionocytes or chloride cells help in active uptake of sodium ions and chloride ions.
