The given question is incomplete. The complete question is:

Albinism is a genetic mutation that results in some animals being born without the enzyme that produces the pigment for skin and eye color. All BUT one statement is a possible explanation for this mutation. Which is NOT an explanation?

A) A DNA base in the gene for the enzyme was removed. B) A DNA base in the gene for the enzyme was substituted. C) The wrong mRNA code caused the wrong protein to form. D) The organism gained an extra chromosome because of a non-disjunction.

Answer:

D) The organism gained an extra chromosome because of a non-disjunction.

Explanation:

Albinism is a genetic disorder and is caused by a genetic mutation. A mutation that changes one or more bases in the gene is called substitution mutation.  A substitution mutation in the gene for pigment production may result in the synthesis of non-functional or less functional pigments and thereby causing albinism.

Similarly, the deletion of one or more bases from the gene for pigment production would also result in the synthesis of a faulty protein. Incorporation of wrong amino acids in the protein by misreading the mRNA codon would result in the production of faulty pigment molecules.

However, a mutation that adds one extra chromosome to the genome of the organism due to non-disjunction of chromosomes during anaphase would not affect the gene for the pigment and thereby cannot cause albinism.

Answer:

D) The organism gained an extra chromosome because of a non-disjunction.

Explanation:

The organism gained an extra chromosome because of a non-disjunction. This would likely cause other mutations to appear. This explanation would not cause the organism to be missing the gene needed for pigment.

Why would it be wise for a woman carrying the hemophilia gene to keep her son from being circumcised?
xenn [34]

Answer:

Because the probability of hemophilia would be 1:4

Explanation:

Hemophilia is a disease that comes with a sex chromosome (pair 46).

It is a recessive allele associated with chromosome X, women have two X chromosomes they can carry it, but they don't have it because they have another dominand allele non-hemophilic.

If you draw a Punnet square with a non-hemophilic father and a carrying mother, you'll found you have 1:4 chances of having a baby boy with hemophilia.

Carrying mother = X(H)X(h)

Father = X(H) Y

A laboring client who is positive for group B Streptococcus (GBS) is given an initial dose of 2 g of ampicillin at 9 AM. Accordi
Vikki [24]

Answer:

The next dose will be 1 g of ampicillin after 4 hours.

Intrapartum antibiotic administration to women with group B that tested ampicillin or penicillin G, either antibiotic should first be considered for(2 g of ampicillin IV followed by 1 g every four hours until giving birth.

Explanation:

Group B streptococci (GBS) colonizes the vagina and rectum in 10–30% of pregnant women.1 In the newborn, GBS is a leading cause of neonatal sepsis and a major cause of pneumonia and meningitis.2

In 2002, the Centers for Disease Control and Prevention (CDC) issued guidelines to recommend that all pregnant women be screened at 35–37 weeks of gestation for GBS and, if positive, treated with intrapartum antibiotic prophylaxis. The aims of prophylaxis are 1) to decrease colony counts at the time of delivery; 2) to prevent the organism from ascending and proliferating in the amniotic fluid compartment; and 3) to achieve adequate levels of effective antibiotic in the fetal bloodstream during labor.

For Ampicillin  nonallergic patients, the protocol recommends a 2 g unit infusion of ampicillin, followed by 1 g  every 4 hours until delivery.3 At least 4 hours of intrapartum antibiotic prophylaxis are recommended.

In science why is it important to have more than one piece of evidence to support your claim?
My name is Ann [436]

Answer:

It is important to have more than one piece of evidence to make sure that the evidence is actually evidence. Or in other words, that the evidence is proven true. With only one piece of evidence, you can't be fully sure if calculations were correct, if the source was trustworthy, etc.

Multiple evidence is kinda like double checking math problems. If you don't do it, you can't be 100% certain the answer is correct.
