1. In the K-capture process, a type of electron capture, from which electron shell does the electron get captured?

Correct answer: B

Rationale: The K-capture process involves the capture of an electron from the innermost electron shell, known as the K-shell. The K-shell comprises s and p orbitals. During the K-capture process, an electron is specifically captured from an inner p-orbital within the K-shell. Choices A, C, and D are incorrect because K-capture involves capturing an electron from the innermost shell (K-shell) which consists of s and p orbitals, not the outermost s-orbital, inner d-orbital, or any available electron shell.

2. What is the formula for calculating molarity?

Correct answer: A

Rationale: The correct formula for calculating molarity is M = n/V. In this formula, 'M' represents molarity, 'n' represents the number of moles of solute, and 'V' represents the volume of the solution in liters. Molarity is defined as the number of moles of solute per liter of solution, hence the ratio of moles to volume. Choice B, 'M = n/L', is incorrect because 'L' should represent liters instead of the number of moles. Choice C, 'M = mol/L', is incorrect as it does not include the representation of the number of moles 'n'. Choice D, 'M = mol/dm³', is incorrect because 'dm³' is a volume unit equal to a liter, but the correct representation should be in terms of the volume of the solution in liters. Therefore, the correct answer is M = n/V.

3. What is the name of the condition characterized by swelling caused by a buildup of lymph fluid?

Correct answer: B

Rationale: Edema is the condition characterized by swelling caused by a buildup of lymph fluid. It occurs when excess fluid is trapped in the body's tissues. Anemia (A) is a condition characterized by a lack of healthy red blood cells, leading to a reduced ability to carry oxygen in the blood. Hypertension (C) is high blood pressure, a condition where the force of the blood against the artery walls is too high. Diabetes (D) is a condition characterized by high blood sugar levels, either due to insufficient insulin production or the body's resistance to insulin, leading to various complications.

4. Blood type is a trait determined by multiple alleles, with IA coding for A blood, IB coding for B blood, and i coding for O blood being recessive. If an individual with A heterozygosity and an O individual have a child, what is the probability that the child will have A blood?

Correct answer: B

Rationale: When an A heterozygote individual (IAi) and an O individual (ii) have a child, there are four possible combinations of alleles that the child can inherit: IA from the A parent and i from the O parent; IA from the A parent and i from the O parent; i from the A parent and i from the O parent; i from the A parent and i from the O parent. Out of these combinations, 50% of the offspring will inherit the A allele from the A parent, resulting in A blood type. Therefore, the correct answer is 50%. Choice A is incorrect because the probability is not 25%. Choice C is incorrect as it overestimates the likelihood. Choice D is incorrect as it suggests a certainty which is not the case in genetics.

5. What is correct about the hormones that stimulate male and female organs to produce male and female sex hormones?

Correct answer: C

Rationale: The correct answer is C. The same hormones stimulate both male and female organs to produce sex hormones. Hormones such as luteinizing hormone (LH) and follicle-stimulating hormone (FSH) are produced by the pituitary gland and act on the ovaries in females and the testes in males to stimulate the production of sex hormones (estrogen and progesterone in females, testosterone in males). Therefore, the same hormones stimulate both male and female organs to produce sex hormones. Choices A, B, and D are incorrect because they do not accurately describe the relationship between hormones and the stimulation of male and female organs to produce sex hormones.
