Which of these would be true concerning mitochondria and nerve cells? A) free-floating mitochondria in the blood plasma creates the energy needed for the neurons
B) mitochondria are not found in nerve cells as nerves use a different type of energy than ATP to function
C) all of the ATP for nerve cells is transported to from the mitochondria in other cells directly to the nerve cells
D) due to the high energy demand of neurons, the mitochondria help produce large amounts of ATP are needed for neurotransmission

D) due to the high energy demand of neurons, the mitochondria help produce large amounts of ATP are needed for neurotransmission

Explanation:

Nerve cells require a large amount of ATP to be able to transport signals throughout the body. This ATP is made by the mitochondria.

huh

explanation:

the last one: artificial selection/genetic engineering

plant breeding is modifying the genetic composition of the plant - but this isn't cloning (which is specifically introducing a gene into a genome). but you are artificially selecting for the phenotype that you want.

the second one is literally genetic engineering - the gene would have been cloned first and then inserted or genetically engineered into the new plant cell (the cotton).
