In animal cells the main microtubule organizing center (or centrosome) is important in cell division. True False

True

Explanation:

In cell biology, the centrosome is the main microtubule organizing center that is important for cell division. The major function of  the centrosome is to maintain the chromosome number during cell division.

Other function of centrosome during cell division include initiate the changes in cell membrane shape through phagocytosis and organize microtubules in mitosis that ensures the distribution of the centrosomes into daughter cell.

Hence, the given statement is true.

the farther away the object is from the central star (the sun) it's gravitainal pull on the object is weaker when it is farther

explanation:

stimulus is a change in the environment that causes an organism to react. the response is the reaction to the stimulus. some examples of stimuli for zebras are drought, to many predators, and bad feeding grounds such as dead grass or plants. zebras respond to stimuli just like all other living organisms
