Answer:
The correct answer is "regulate body fluid by controlling excretion from sweat glands".
Explanation:
Regulate body fluid by controlling excretion from sweat glands is not a function of the kidneys. The kidneys regulate body fluid by controlling the level of water that it is excreted in the urine. The brain and the sweat glands themselves are the two organs that control the level of body fluids from sweat glands, and by doing this they allow body fluid homeostasis.
Answer:
Independent variable: Salinity/Salt concentration
Dependent variable: hatching rate
Explanation:
As rightly stated in this question, INDEPENDENT VARIABLE, in an experiment, is the variable that the experimenter changes or manipulates in order to bring about a measurable response while the DEPENDENT VARIABLE is the variable that the experimenter measures in an experiment. Dependent variable as the name implies is dependent on the independent variable.
In this question where an hypothesis was given as follows: "Hatching brine shrimp is related to salinity (how salty the water is), then the greater the salt concentration, the higher the hatching rate". The hypothesis relates the independent and dependent variables i.e. it tells us how the independent variable affects the dependent variable.
Hence, according to the hypothesis, it is telling us how a change in SALINITY OR SALT CONCENTRATION will affect HATCHING RATE. Therefore;
Independent variable: SALINITY/SALT CONCENTRATION
Dependent variable: HATCHING RATE
