The correct answer is (c) They show which part of the brain are involved in specific activities.

The functional  magnetic resonance imaging is used to measure the activity of brain by the detecting the change in the blood flow. This is done because the cerebral blood flow is associated with the neuronal activation. The functional area of brain has a higher blood flow that can be observed in functional MRI. The commercial application of functional magnetic resonance imaging is used in lie detectors. This technique is also used in research world and in some clinical trails. Physicians use this technique to see how risky a brain surgery can be. It is also used to learn how a normal, diseased, or injured brain functions.

Which of the following are matched correctly?
kogti [31]

Answer:

<u>1. type IV hypersensitivity: delayed-type hypersensitivity.  </u>

<u>2. type I hypersensitivity: IgE  </u>

<u>3. type II hypersensitivity: IgG  </u>

<u>4. type III hypersensitivity: immune complexes </u>

Explanation:

Type IV hypersensitivity is cell mediated hypersensitivity rather than antibodies as in all other types of hypersensitivities. It is also known as delayed type hypersensitivity because it usually respond in 2-3 days via T-Lymphocytes rather than antibodies like IgE or IgG. So we can say that in option 5 is mismatched as it relates type IV to IgG antibodies.

ndividuals III-6 and III-7 have two little monstersand are expecting a third one. Their two childrenhave two eyes. What is the c
CaHeK987 [17]

Answer:

The correct answer is - 75% or 3/4.

Explanation:

In the given question, there is a cross between III-6 and III-7 that produced two double eyes monsters and expected one more. As given in the image that the A or single eye is dominant over the a or double eye then both parents must be heterozygous as they produced double eye offspring (aa) and they do have only one eye.

then chances of single eye offspring would be -

cross: Aa and Aa

gametes: A, a and A, a

Punnett square:

           A      a

A         AA     Aa

a         Aa      aa

so there are 75% chances to have a single eye and 25% chances for a double eye.
