Answer:

Explanation:

Although yeast is a one-celled fungus, most fungi are multicellular organisms. Fungi are eukaryotes, meaning they have a cell nucleus. Like plants, fungi have cell walls and do not move on their own. Unlike plants, however, fungi cannot produce their own food because they do not have chloroplasts.

Arte-miy333 [17]

The answer is x-linked recessive. It is apparent that the color blindness affects the males hence it's caused by a sex-linked recessive gene. Males have XY homologous chromosomes. The X sister chromosome has more genes than the Y sister chromosome, hence most males are hemizygous for sex linked genes. This means that even recessive genes on the X chromosome are likely to be expressed in males.

Ugo [173]

Answer:

Voltage-gated Ca2+ channels

Explanation:

Modulation of Ca+2 channel Epinephrine also causes an increase in cAMP that stimulates PKA that is protein kinase A, which in turn phosphorylates the voltage-gated Ca+2 channel that is the L channel. This phosphorylation results in a protein conformational change that enchances the channels activity.

goblinko [34]

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.

Note: This answer is very generic based on the statement of the question. If you have some specific options of the questions, please post it again with them or comment. Thank you.
