Which of the following is used to determine a person's DNA sequence? 

A. Enzymes

B. Blood types

C. Hormones

D. Genes

Answer Explanation:

Genes are used in the process of DNA sequencing to determine the order of nucleotides in a DNA molecule.

Choice B.

Blood types is not the correct answer because blood types are determined by the presence or absence of specific antigens on the surface of red blood cells and are not directly related to DNA sequencing.

Choice C.

Hormones is not the correct answer because hormones are chemical messengers produced by glands in the body and are not directly involved in DNA sequencing.

Choice D.

Genes is the correct answer because genes are used in the process of DNA sequencing to determine the order of nucleotides in a DNA molecule.

Therefore, the Correct Answer is D.

Q #1: Which of the following statements best supports the hypothesis that viruses can cause cancer?

A. Cancerous and normal cells share genetic sequences

B. Cellular DNA has sequences related to viral sequences

C. Viruses and cancer cells both replicate rapidly.

D. Genes that regulate cell division are found in some viruses

Answer Explanation

Genes that regulate cell division are found in some viruses.

When viruses cause an infection, they spread their DNA, affecting healthy cells’ genetic makeup and potentially causing them to turn into cancer.

For instance, HPV infections cause the virus’ DNA to combine with the host’s DNA, disrupting the normal function of cells.

Choice A is not correct because cancerous and normal cells sharing genetic sequences does not support the hypothesis that viruses can cause cancer.

Choice B is not correct because cellular DNA having sequences related to viral sequences does not support the hypothesis that viruses can cause cancer.

Choice C is not correct because viruses and cancer cells both replicating rapidly does not support the hypothesis that viruses can cause cancer.
Q #2: Parasitic worm infestation is hypothesized to be damaging to the host. However, scientists have recently discovered that worm infestation can relieve the effects of certain autoimmune disorders. In which of the following ways should the hypothesis be modified, given the new findings?  

A. Worm infestation prevents the body from immune malfunction

B. Worm infestation reduces the severity of certain autoimmune disorders

C. Worm infestations exacerbate the body's immune reactions

D. Lack of worm infestations is the cause of some autoimmune disorders

Answer Explanation

The hypothesis should be modified to include the new findings that worm infestation can relieve the effects of certain autoimmune disorders.

A possible modification could be: “Parasitic worm infestation can have both damaging and beneficial effects on the host.

While it can cause harm, it has also been found to reduce the severity of certain autoimmune disorders.”

Choice A.

Worm infestation prevents the body from immune malfunction is not correct because it overstates the findings and implies that worm infestation completely prevents immune malfunction, which is not supported by the evidence.

Choice C.

Worm infestations exacerbate the body’s immune reactions is not correct because it contradicts the new findings that worm infestation can relieve the effects of certain autoimmune disorders.

Choice D.

Lack of worm infestations is the cause of some autoimmune disorders is not correct because it overstates the findings and implies a causal relationship between lack of worm infestations and autoimmune disorders, which is not supported by the evidence.
Q #3: Which of the following substances is excreted by sweat glands in response to the breakdown of proteins and the formation of ammonia?

A. Urea

B. Sebum

C. Water

D. Lysozymes

Answer Explanation

Urea is a substance that is excreted by sweat glands in response to the breakdown of proteins and the formation of ammonia.

When proteins are broken down, they produce ammonia, which is a highly toxic compound for the body.

Ammonia is then converted into urea and released out of the body through sweat glands.

Choice B.

Sebum is not correct because it is an oily substance secreted by sebaceous glands to lubricate and protect the skin, but it is not related to the breakdown of proteins or the formation of ammonia.

Choice C.

Water is not correct because while it is a component of sweat, it is not specifically related to the breakdown of proteins or the formation of ammonia.

Choice D.

Lysozymes are not correct because they are enzymes found in tears, saliva and other body fluids that have antibacterial properties, but they are not related to the breakdown of proteins or the formation of ammonia.
