what role does molecular evidence play in determining how closely two species are related to each other?
worty [1.4K]
The molecular technique is used to distinguish and evaluate the similarities and differences of the genomes of the various organisms of the same species. This method was first discovered by Charles Darwin when he did research in the Galapagos Islands. He was able to see the similarities and the difference between species depending on how they adapt to their physical environment.

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)
