Chemistry

1. What is the term for the chemical reaction that involves the loss of electrons?

Correct answer: b

Rationale: Oxidation is the chemical reaction that involves the loss of electrons. The other choices describe different types of reactions.

2. Which hormone, produced by the pancreas, acts in opposition to insulin by increasing blood sugar levels?

Correct answer: b

Rationale: The correct answer is B: Glucagon. Glucagon is a hormone produced by the pancreas that acts in opposition to insulin. When blood sugar levels are low, glucagon stimulates the liver to convert stored glycogen into glucose, which raises blood sugar levels. Insulin, on the other hand, lowers blood sugar levels by promoting the uptake and storage of glucose. Cortisol, produced by the adrenal glands, plays a role in stress response and metabolism but does not directly regulate blood sugar levels. Thyroxine, produced by the thyroid gland, regulates metabolism but does not directly affect blood sugar levels. Therefore, glucagon is the hormone that acts in opposition to insulin by increasing blood sugar levels.

3. Which of the following is NOT a part of the body's innate immune response?

Correct answer: D

Rationale: The correct answer is D. The body's innate immune response is the first line of defense against pathogens, and it includes physical barriers like skin and mucous membranes (option A), phagocytes that engulf and destroy pathogens (option B), and the inflammatory response to isolate and contain infections (option C). The production of antibodies specific to a particular pathogen (option D) is part of the adaptive immune response, which develops over time and is not considered part of the innate immune system. Therefore, option D is not a component of the body's innate immune response.

4. How does an increase in mass affect the force required to produce the same acceleration on an object?

Correct answer: a

Rationale: With an increase in mass, more force is needed to produce the same acceleration due to inertia.

5. What is the term for a solution that has a lower concentration of solute compared to another solution?

Correct answer: C

Rationale: A dilute solution has a lower concentration of solute compared to another solution. The other choices do not accurately describe a dilute solution.

6. Which type of RNA carries the genetic code from DNA to ribosomes?

Correct answer: C

Rationale: Rationale: - Messenger RNA (mRNA) carries the genetic information from DNA in the cell's nucleus to the ribosomes in the cytoplasm, where protein synthesis occurs. - Ribosomal RNA (rRNA) is a component of the ribosomes where protein synthesis takes place. - Transfer RNA (tRNA) is responsible for bringing amino acids to the ribosomes during protein synthesis. - Deoxyribonucleic acid (DNA) is the genetic material that contains the instructions for building and maintaining an organism. DNA is transcribed into mRNA before being translated into proteins.
