1. what process allows the cells of organisms to maintain a constant internal environment even when external conditions change?

a. digestion
b. excretion
c. homeostasis
d. photosynthesis

1. which process can rylee learn about by studying the nucleus of a cell?

a. how waste is removed
b. how water is collected and stored

Explanation:

Question 1

The question is about the process that allows cells to maintain a constant internal environment despite external changes. Homeostasis is the process by which organisms maintain a stable internal environment. Digestion is about breaking down food, excretion is removing waste, and photosynthesis is how plants make food. So the correct answer is related to homeostasis.

The nucleus controls cell activities. Waste removal is a cell process regulated by the nucleus (as it controls the cell's functions and genetic instructions for processes like waste management). Water collection and storage is more related to organelles like vacuoles, not directly the nucleus. So studying the nucleus would help learn about how waste is removed (as the nucleus regulates the cell processes involved in waste removal).

Answer:

C. homeostasis

Question 2

(Note: The options seem a bit unclear in relation to studying the nucleus, but assuming typical cell nucleus functions related to genetic information and cell processes, and analyzing the options: The nucleus is involved in controlling cell activities including processes like waste removal (through controlling cell functions that handle waste), while water collection/storage is more related to structures like vacuoles. So if we assume the best fit among the given, studying the nucleus would relate to how the cell (and thus waste removal as a cell - controlled process) works. But this depends on the full context. However, based on the options, the most relevant to nucleus - related study (as nucleus controls cell functions) would be A as waste removal is a cell process controlled by nucleus - related genetic and regulatory mechanisms, while water collection/storage is more about other organelles. )
