Answer:

Chimpanzee

Explanation:

It is said that all the species are evolved from a common ancestor. We humans also come from this way. But we have close ancestors i.e. apes

( Chimpanzee). It is proved by the nucleotide sequence of the DNA.

The molecular data shows the similarity between the DNA of banana and humans is 50 %, 80% similarity with dogs, and 99% with the chimpanzee.

Due to natural selection, the apes and humans are split and form 2 species. But one can say humans are great apes, due to this close similarity between the nucleotide sequences. When the nitrogenous base sequence is compared, the apes and chimpanzee shows many similarities.

There are some differences also, the chimpanzee has 24 pairs of chromosomes, while humans have 23 pairs. There are many differences shows in both nucleotide sequences. This is because of the mutation. After these differences, the chimpanzees are closely related to humans.

In the cranial nerve model, which best describes the location of the optic chasma:________

eimsori [14]

Answer:

Cranial Nerves:

The cranial nerves are the set of 12 pairs of nerves which are originated from the brain. As they are responsible for some of the essential functions , such as vision, smell, and balance of the human body structure.

The 12 pairs of the cranial nerves are as as under:

The olfactory nerve
The optic nerve
The oculomotor nerve
The trochlear nerve
The trigeminal nerve
The abducens nerve
The facial nerve
The vestibulocochlear nerve
The glossopharyngeal nerve
The vagus nerve
The spinal accessory
The hypoglossal nerve,

It is very hard for the students to remember all the names of the cranial nerves as we can just recall them by memorizing the device-Old Opie Occasionally Tries Trigonometry And Feels Very Gloomy, Vague And Hypoactive.

Explanation:

Optic chasma:

The optic chasma originates as one of the cranial nerves, as it serves for the function of vision sense in human body. The nerves are responsible for carrying the set of information and data from the retina of the eye to the brain. As the communication between the two regions or part of the body, as they hold the capacity to carry the charges or information from the retina of the eye towards the brain.
