7) Homeostasis refers to an organism’s ability to maintain stable internal conditions. This is important
because
a. Some enzymes only work at certain temperatures
b. Different pH levels can cause chemical reactions to occur or stop occurring
c. Cells requiring a certain environment may not be able to function if they end up in hypertonic or

a. were multicellular organisms.
c. were single-celled organisms
b. lived on land.
d. resembled today’s plants.
9) Why do scientists organize living things into groups?
a. so they can find them in the wild more easily
b. so they can make sense of the variety of rocks on Earth
c. so that the organisms are easier to study

A. The water is hypertonic to the vegetable cells and helps add water to those cells
B. The water is hypotonic to the vegetable cells and helps add water to those cells
C. The water is isotonic to the vegetable cells and helps add water to those cells
D. Not enough info is given to answer this question
E. All of these are possible with normal plant cells

B. The salt water is hypotonic to the vegetable cells and helps add water to those cells
C. The salt water is isotonic to the vegetable cells and helps keep those cells the same
D. The salt water is hypertonic to the vegetable cells and helps remove water from those cells
E. The salt water is hypotonic to the vegetable cells and helps remove water from those cells
