Researchers can genetically select lettuce crops to cultivate plants that are pest-resistant. one of the concerns of genetically selected crops is that some traits such as tough leaves for pest resistance may affect a suitable taste and texture desired by humans for eating. what question could be asked to begin this investigation by looking at a measurable dependent variable? what is the effect of crop selection for pest resistance on the taste and texture most preferred for consumption by humans? what is the effect of crop selection for pest resistance on the distribution of leaf size in a population of plants? what is the effect of crop selection for pest resistance on the sale of green salad in grocery stores? what is the effect of crop selection for pest resistance on the taste and texture most preferred for consumption by grasshoppers?

The answer is B

Explanation:

the answer that best describes the relative refractory period in the neuron is the resting membrane potential is restored, but concentrations of sodium and potassium are not restored to their original state.

the refractory period is the time during which another stimulus given to the neuron will not lead to a second potential. thus, because na+ channels are inactivated during this time, additional depolarizing stimuli do not lead to new action potentials.

foliated

[ explanation ]

foliation forms in a rock when pressure squeezes the rock together. the rock then has a design of many different color little lines. there are three types of foliated rock. the types are slate, schist, and gneiss. each type of foliated rock is different based on grain size and foliation characteristics. the lines appear when the rock has been under pressure.
