Which of the following is NOT made of proteins?

In humans there is a dominant allele (A) for the absence of moles; while the recessive allele (a) results in the presence of mol

Art [367]

Answer:

a. $(p + q)^7$ = $p^7q^0+7p^6q+21p^5q^2+35p^4q^3+35p^3q^4+21p^2q^5+7pq^6+p^0q^7$

b. i. 0.75

ii. 0.000061

iii. 0.012

iv. 0.17

c. 0.67

Explanation:

a. The expansion of the binomial (p + q)7 would be such that:

$(p + q)^7$ = $p^7q^0+7p^6q+21p^5q^2+35p^4q^3+35p^3q^4+21p^2q^5+7pq^6+p^0q^7$

b. Both couples are heterozygous:

Aa x Aa

AA Aa Aa aa

Since A is dominant over a,

probability of having mole (aa) = 1/4

probability of not having moles = 3/4

Therefore, the probability of the first child not having moles = 3/4 or 0.75

ii. Let the probability of not having mole = p and the probability of having mole = q. From the binomial expansion:

$(p + q)^7$ = $p^7q^0+7p^6q+21p^5q^2+35p^4q^3+35p^3q^4+21p^2q^5+7pq^6+p^0q^7$

Probability that all of the children will have moles = $p^0q^7$

since p = 3/4 and q = 1/4

$p^0q^7$ = $(3/4)^0(1/4)^7$ = 0.000061

iii. Probability that the first two children will have no moles and the last five will have moles = $21p^2q5$

= $21(3/4)^2(1/4)^5$

= 0.012

iv. Probability that 4 will have no moles and 3 will have moles out of the 7 children = $35p^4q^3$

= $35(3/4)^4(1/4)^3$

= 0.17

c. Probability that the child born without moles is a carrier of the a-allele = probability of heterozygous.

From the cross in (b), the genotypes of those born without moles are AA and 2Aa. Therefore, the probability of not having moles and be Aa is:

= 2/3 or 0.67

Which function of a client’s eyes ensures formation of a single image of close objects being seen?

vesna_86 [32]

The eye convergence effect allows you to see only one image of nearby objects. Mydriasis is the dilation of the pupil when you reduce light or see into the distance.

<h3>Describe the structure of the human eye.</h3>

Each eye constantly adjusts the amount of light it receives, focusing on both near and far objects, producing a continuous image that is instantly transmitted to the brain. The orbit is a cavity of bone that contains the eyeball, muscles, nerves, blood vessels, and structures that produce and drain tears. The eyeball is made up of three layers, including the optically transparent aqueous humor, the lens, and the vitreous.

The outermost layer consists of the cornea and sclera.
The middle layer contains the main blood supply of the eye.
The inner layer consists from back to front of the choroid, ciliary body and iris.

This is a biochemical process used for determining the order of the nucleotide bases, adenine, guanine, cytosine, and thymine, i

Romashka-Z-Leto [24]

Answer: Southern blot

Explanation:

The techniques of Southern blotting helps to identify specific sequences of DNA among two or more samples that have been collected from organisms to be investigated.

This biochemical process also involves electrophoresis and hybridization of DNA to obtain the right order of the nucleotide bases, as similar order of bases would infer COMMON ANCESTRY between the two organisms.

Is it true that the intestinal microflora synthesize small amounts of vitamin d?

Minchanka [31]

It is false that the intestinal microflora synthesize Vitamin D. Intestinal Microflora is a helpful bacteria that helps in the process of digestion. This also helps the body in protecting against infection and develops immune system and this synthesis of vitamins gives nutrition to body.
