Which of the following substances is excreted by sweat glands in response to the breakdown of proteins and the formation of ammonia?
A. Lysozymes
B. Urea
C. Water
D. Sebum
Urea is a waste product that is formed when proteins are broken down in the body. It is excreted by the kidneys in urine, but small amounts can also be excreted by sweat glands in sweat.
The other options are not substances that are excreted by sweat glands in response to the breakdown of proteins and the formation of ammonia. Lysozymes are enzymes that break down bacterial cell walls, water is a component of sweat but is not specifically related to protein breakdown, and sebum is an oily substance produced by sebaceous glands to lubricate the skin.
Therefore, the Correct Answer is B.

Q #1: Which of the following is a protein present in blood plasma?
A. Monocytes
B. Platelets
C. Fibrinogen
D. Lymphocytes
Answer Explanation
The correct answer is c. Fibrinogen. Fibrinogen is a protein present in blood plasma that plays a key role in blood clotting. When an injury occurs and bleeding begins, fibrinogen is converted into fibrin, which forms a mesh-like structure that helps to trap blood cells and form a clot.
A. Monocytes are a type of white blood cell, not a protein present in blood plasma.
B. Platelets are cell fragments that play a role in blood clotting, but they are not a protein present in blood plasma.
D. Lymphocytes are a type of white blood cell, not a protein present in blood plasma.

Q #2: Punnet Square An organism with an unknown genotype is crossed with another organism that shows the recessive trait (aa). The Punnet square below shows the results. Which of the following is the unknown genotype? Unknown Unkonwn a Aa aa a Aa aa
A. a
B. Aa
C. aa
D. AA
Answer Explanation
The unknown genotype is Aa. This can be inferred from the Punnet square, which shows that half of the offspring are Aa and half are aa. This indicates that the unknown parent must have one dominant allele (A) and one recessive allele (a), making its genotype Aa.
The other options are not correct because they do not match the results shown in the Punnet square. If the unknown genotype was aa or AA, all of the offspring would have the same genotype as their parent. If the unknown genotype was a, it would not be a valid genotype as it only has one allele.
