A. Genetic technology will have no measurable effect on the food supply.
B. Genetic technology will increase the cost of many foods and harm their quality.
C. Genetic technology will improve the quality of many foods, but also increase their cost.
D. Genetic technology has the potential to reduce the cost of many foods and improve their quality.

he forelimbs below belong to four species that descended in a direct line from the ancestral mammal shown above. of the four descendants shown, which species most likely appeared earliest in evolutionary history?

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

her next move would be to use agarose gel electrophoresis to separate the dna molecules of varying length and create a dna fingerprint.
