Create a mutant fly with any number of variations and mate it with a wild-type fly. How many offspring are wild-type? What are the
phenotypes of the flies that are not wild-type?

i believe it is "they are not used up by reactions" as the answer to your question, text me back if this is correct because i just learned this.

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

wegner's theory did not explain how the continents could move

explanation:

protein makes up the building blocks of organs, muscles, skin, hormones and pretty much everything that matters in your body.

some choices are:

peanut butter

seeds

eggs

yogurt

meats

fish

so pretty much meat, dairy, nuts, and grains.
