Which of the following are part of the body’s first line of defense against pathogens?
Fed [463]

The answer is "D"

The body's first line of defense is also known as Innate immunity and incudes mucous membranes. Both the intact skin and mucous membranes of the body offer a high degree of protection against pathogens.

 A good example is the mucous membrane of the respiratory tract. It is lined up with cilia and covered with mucus. The coordinated beating of the cilia drives the mucus up to the nose and mouth where the trapped bacteria can be expelled.

(Lymph nodes and white blood cells belong to the second line of defense, not the first)

Use the chart above to determine which substitution mutation has the potential to cause more damage? Highlight your answer. (2pt
icang [17]

Answer:

This question is incomplete

Explanation:

This question is incomplete because of the absence of the chart referred to in the question. However, what appears to be the case is that the three nitrogenous bases represent codons (and the missing chart is the codon chart). The mutation that has the potential to cause more damage will be the one that would change the amino acid formed from the codon change.

A. CAU to CAC: The codons CAU and CAC both form the amino acid histidine and thus is not expected to cause a major damage.

B. UGU to UGC: The codons UGU and UGC both form the amino acid cysteine and thus is not expected to cause a major damage.

C. UCU to UUU: <u>Codon UCU forms the amino acid serine while the codon UUU forms the amino acid phenylalanine</u>. Thus, this eventual change in the amino acid formed has the potential to cause a major damage and thus option C is the correct option.

NOTE that a codon is a sequence of three DNA/RNA nucleotides that corresponds to a single amino acid.
