Briefly describe Wernicke and Broca aphasia. What is a main difference of these two classic types of aphasia and can be useful i
mixer [17]

Answer:

Broca's area refers to a motor speech region, which assists in movements needed at the time of the production of speech. When an injury takes place in the frontal parts of the left hemisphere, it can give rise to various kinds of language issues. This section of the brain plays an essential role in putting words together to produce complete sentences. The injury to the left hemisphere is known as Broca's aphasia, also known as expressive aphasia.  

Wernicke's aphasia also called receptive aphasia, posterior aphasia, or sensory aphasia is a kind of aphasia in which individual encounters with difficulty in understanding spoken and written language. Thus, the two kinds of aphasia are expressive aphasia in which one faces difficulty in conveying thoughts via writing and speech. The other is receptive aphasia, in which one finds difficulty in understanding the written or spoken language.  

By analyzing the symptoms that whether the patient exhibits difficulty in understanding speech and using accurate words to express thoughts or the movements that are needed to generate speech, one can find the site of destruction.

What were the two driving forces that drove the evolution in the variation of skin color
yarga [219]

Answer:

The correct answer is: geography and UV radiation.

Explanation:

Skin variation occurred thanks to evolution, and was driven as a consequence of the geographical location of different populations of humans.

The humans that lived in hot and sunny places, closer to the equator, where much more exposed to the sun's ultraviolet radiation. In order to survive the amount of UV lights that they were exposed to, new humans in those regions were being born with a darker skin tone, which was rich in melanin (a brown pigment that protects us from the sun radiation).

Contrary to these humans that lived in the tropical areas, the humans that populated the areas that were closer to the poles, developed much lighter skin as a result of lower amounts of melanin in their skin. Since sun exposure in the poles is very limited, humans needed to receive as much as they could for the production of Vitamin D, and thus, their skins got lighter and less protected.
