lyudmila [28]

Answer:

The answer is:

verbally report that a cat was seen

write the word cat using their left hand

Explanation:

"Split-brain" is<em> a condition of having "two brains" in one body.</em> This is also known as "callosal syndrome." This happens when a person experiences seizure and in order to control it, the "corpus callosum" (divides the lobes into left and right hemispheres) is being severed. Once it is severed, the hemispheres will function as a <em>separated brain.</em> This treatment is only done as a last resort.

The person who has a split-brain will have two separate perceptions and impulses of things.

In the situation above, the patient is shown a picture of a cat in the right visual field. This means that the image of the cat will be sent to his left hemisphere. Left hemisphere is more active when it comes to the production of speech, thus the patient will be able to verbally report that a cat was seen. (thus, this explains the answer).

Since the left hemisphere is also responsible for "writing," then he can also write the word "cat" using his left hand. (thus, this explains the answer)

Allisa [31]

Answer:

c) repeat the cell cycle continuously

Explanation:

Cell division is a normal phenomenon for all cells as this is the way the cell reproduces and gets repaired in living organisms. However, some cells, due to mutation, keeps dividing and proliferating to form tumours. These cells are called CANCER cells. A normal cell undergoes cellular repair at certain checkpoints of the cell cycle. The checkpoints are necessary to determine a faulty cell and stop its division.

However, cancerous cells do not undergo any repair, which is why they do not enter the G0 phase as mentioned in the question. They keep on dividing out of control without death by repeating the cell cycle continuously.
