The complementary strand of DNA is formed by pairing complementary bases. In DNA, adenine (A) pairs with thymine (T), and guanine (G) pairs with cytosine (C). Additionally, RNA uses uracil (U) instead of thymine.
Given the sequence 5' AGCTAGCGT 3', the complementary strand would read:
3' TCGATCGCA 5'
Therefore, the Correct Answer is D.

Question 1:
Which of the following is the term given to the sequence of nucleotides that contains the information to make a specific protein molecule?
A. Locus
B. Promoter
C. Operator
D. Gene
The Correct Answer is D.A gene is a segment of DNA that codes for a specific protein or polypeptide.
Question 2:
Which of the following types of cells stimulates other immune cells to attack and destroy foreign agents?
A. Cytotoxic T-cells
B. Plasma cells
C. Natural killer cells
D. Helper T-Cells
The Correct Answer is D.Helper T cells are important cells that stimulate the action of other immune cells. For instance, they not only help activate B cells to secrete antibodies and macrophages to destroy ingested microbes, but they also help activate cytotoxic T cells to kill infected target cells.
Question 3:
Which of the following nucleotides is only found in RNA?
A. Guanine
B. Thymine
C. Uracil
D. Adenine
The Correct Answer is C.Uracil is the nucleotide that is only found in RNA. The other nucleotides are found in both DNA and RNA
Question 4:
Which of the following body systems breaks down proteins into amino acids?
A. Digestive
B. Excretory
C. Circulatory
D. Endocrine
The Correct Answer is A.The digestive system breaks down complex food substances into small and less complex absorbable compounds. Proteins, for instance, are broken down to constituent amino acids through a digestion process that combines mastication and enzymatic breakdown.
Question 5:
A strand of DNA bases reads 5' AGCTAGCGT 3, what would the sequence of bases on the contemporary strand read?
A. 3' STOGUTCGCU
B. 5' AGCTAGCGT S
C. 3' SUCGAUCICA
D. 3' TCGATCGCA 5'
The Correct Answer is D.The complementary strand of DNA is formed by pairing complementary bases. In DNA, adenine (A) pairs with thymine (T), and guanine (G) pairs with cytosine (C). Additionally, RNA uses uracil (U) instead of thymine.
Given the sequence 5' AGCTAGCGT 3', the complementary strand would read:
3' TCGATCGCA 5'
Question 6:
Which of the following would result in an increase in the chemical reaction?
A. Adding more of the product
B. Decreasing the concentration of the reactant
C. Sealing the reaction in an airtight container
D. Using a mortar and pestle to grind a solid reactant to a powder
The Correct Answer is D.Crushing a solid reactant into powder increases the surface area of the reactant, thereby increasing chemical reaction. This is because more of the reacting molecules or ions are exposed to the other reactant, which increases the chance of particles colliding and leads to more successful collisions per second.
Question 7:
Which of the following distinguishes endocrine and exocrine glands from another?
A. The presence or absence of ducts
B. The effect their secretions have on the target cells
C. The biochemistry of their secretions
D. The presence or absence of nerve innervation
The Correct Answer is A.Exocrine glands secrete their products into ducts that carry them to the target organs. In contrast, endocrine glands secrete their products directly into the bloodstream, which carries them to target cells throughout the body.
Question 8:
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. Lack of worm infestations is the cause of some autoimmune disorders.
B. Worm infestation reduces the severity of certain autoimmune disorders
C. Worm infestation prevents the body from immune malfunction
D. Worm infestations exacerbate the body's immune reactions
The Correct Answer is B.The new findings can be used to generate a hypothesis to reflect the beneficial aspect of worm infestations in certain autoimmune disorders, indicating that they can help reduce the severity of the condition.

Question 10:
Which of the following organs removes nitrogenous waste from the body?
A. Large Intestines
B. Liver
C. Kidneys
D. Gall Bladder
The Correct Answer is C.The kidneys are the primary organs involved in the excretion of nitrogenous wastes. Nitrogenous wastes are mostly products of protein metabolism in the liver. One of the common nitrogenous waste products is urea, which is excreted through the kidneys.
