The answer is <span>B. immune cells that are destroyed by HIV
CD4+ are immune cells (white blood cells) and are an important part of the immune system. Their name comes from the presence of CD4 glycoprotein on their surface. HIV uses CD4 glycoproteins on the surface of CD4+ cells to entry into the cells. The consequence is a reduced number of those cells. Therefore, CD4+ immune cells are destroyed by HIV.</span>
Answer: The correct answer is option C
FACILITATED DIFFUSION.
Explanation: FACILITATED DIFFUSION is a form of passive transport,it is the process by which substances(molecules) move from a region of higher concentration to a region if lower concentration along their concentration gradient through the help of a membrane transporter forming a pore or channel(Protein).
Facilitated diffusion dies not require high energy to occur since a concentration gradient is involved.

Answer:
The wechsler intelligence scale for children (WISC) is a good indicator of innate "genetic" ability for children of six to sixteen years old.
Explanation:
Wechsler Intelligence Scale for Children (WISC) is basically a system of testing IQ of children from six to sixteen years old. This testing was created by David Wechsler, who stated that intelligence is a global quality and it should be reflected in children's verbal as well as non-verbal abilities.
This testing system is used by schools for several purposes:
• To evaluate the performance of kids during placement process.
• It is also used to evaluate abilities of dis-abled children or deferentially able children.
• IQ scores from WISC can be used to diagnose the problems of the children such as mental re-tardation or some specific learning dis-ability. It can also be used to determine the problems of the children who face hyperactivity or attention deficiency.
• In addition, the test can also diagnose brain related and neuro-psychological disorder.
Point to remember:
The WISC system is not useful to determine the extreme form of intelligence like IQ below 40 and above 160. Wechsler himself focused on this point many times that test is not adequate for children with IQs of below 70 or above 130. Despite of this fact, people use this test to determine the intelligence of deferentially able children who usually have IQ above 130 that is not very appropriate thing.
