Answer:
Rats with ventromedial lesions should begin overeating; rats with lateral lesions should stop eating
Explanation:
The feeling of hunger stimulates a desire to eat.
The lateral hypothalamus is responsible for making an organism hunger and craves for food upon receiving any stimulation or signal that causes hunger.
A damaged to the lateral hypothalamus would mean the organism would not be able to sense hunger and thus, there would be no desire to eat. Hence, the rats with lateral lesions should stop eating.
On the other hand, the ventromedial hypothalamus is responsible for quenching hunger and signaling to the organism that it is full, hence, it would stop eating. However, when the ventromedial hypothalamus is damaged, the organism would not be able to tell when to stop eating. Hence, rats with ventromedial lesions should begin overeating.

The nervous system sends messages from nerve endings to the brain and from the brain to cells, tissues, and organs. Cells of the nervous system sometimes secrete chemical messengers instead of neurotransmitters. These specialized nervous system cells are called neurosecretory cells, and they produce neurosecretions. Every nerve cells are long, thin cylinders along which electrical disturbances (nerve impulses) travel. the cell membrane of a typical nerve cell consists of an inner and an outer wall separated by a distance of 0.10 μm and the electric field within the cell membrane is 7.0×105n/c.
Answer:
Mitosis is the process a cell goes through to produce two new cell nuclei. Cytokinesis is when the cytoplasm splits. Without cytokinesis, mitosis would create 2 nuclei in one cell. If cytokinesis happened and mitosis did not then the cell would most likely not survive.
