There are three different types of observation methods for the purpose of research. These three methods include the structured observation, participant observation, and the field experiments.
The structured observation is the method of data collection which is done without the direct involvement of the researcher with the participants. the participant observation is the type of observation which is used in the experiments involving qualitative research. The field experiment is the method of observation when the experiment rules are applied in the real world.
Among the given three types of observations, the structured observation is the type of observation that is used while observing the bacteria once a week for a period of a month.
Since they cannot see very well or even at all in some cases, these animals use echolocation instead to orient themselves, to find where they are, and to find food.
Your kidneys act like a filter to remove wastes and extra fluid from your body. Your kidneys filter about 200 quarts of blood each day to make about 1 to 2 quarts of urine
I am not sure what the answer(s) for, "which is not a major function of the kidney?" is but I can guess that your answer for that question might be, regulation of blood cell size. Also, the normal ph range of urine in humans is 6! I hope this helps!
