Correct Answer: D

Rationale: During meiosis, a parent cell undergoes two rounds of cell division resulting in the formation of four daughter cells. 1. In the first division (meiosis I), homologous chromosomes separate, resulting in two daughter cells with half the number of chromosomes as the parent cell. 2. In the second division (meiosis II), sister chromatids separate, producing a total of four daughter cells, each with a haploid set of chromosomes. Therefore, the correct answer is D: Four. Choices A, B, and C are incorrect because meiosis specifically leads to the formation of four daughter cells, not one, two, or three.

Correct Answer: B

Rationale: The correct answer is B (50%). When an A heterozygote (IAi) individual and an O (ii) individual have a child, the possible genotypes of the offspring are IAi (A blood type) and ii (O blood type). Since A and O blood types are determined by codominant and recessive alleles respectively, the child has a 50% chance of inheriting the A allele from the A heterozygote parent, resulting in A blood type. Therefore, the probability of the child having A blood type is 50%. Choice A (25%) is incorrect because it does not consider the possibility of the child inheriting the A allele from the A heterozygote parent. Choice C (75%) and choice D (100%) are incorrect as they overestimate the probability by not accounting for the presence of the O allele in the O parent, which would result in the child having O blood type.

Correct Answer: B

Rationale: A neutralization reaction involves the combination of an acid and a base to produce a salt and water. This type of reaction is characterized by the formation of a salt through the exchange of ions. In contrast, oxidation reactions involve the loss of electrons, synthesis reactions involve the combination of substances to form a new compound, and decomposition reactions involve the breakdown of a compound into simpler substances. Therefore, the correct answer is B because it specifically results in the production of a salt.

Correct Answer: A

Rationale: The correct answer is A: They're both accurate and precise. Rationale: 1. Accuracy: The measurements are close to the accepted value of 9.8 m/s^2, with a range of 9.78-9.81 m/s^2. 2. Precision: The measurements are consistent and clustered closely around the true value, indicating precision. 3. The slight variations in measurements are expected due to experimental error but still fall within an acceptable range. In summary, the measurements are accurate as they are close to the true value, and they are precise as they are clustered closely together. Other choices are incorrect because they do not accurately reflect the situation based on the provided data.

Correct Answer: D

Rationale: The correct answer is D because bones are resistant to shattering due to the intricate balance of minerals like calcium and phosphorus, along with collagen fibers. Calcium salts alone (choice A) only provide hardness, not flexibility. Collagen fibers (choice B) provide strength but not hardness. Bone marrow and blood vessels (choice C) support bone health but don't contribute directly to resistance to shattering. The combination of minerals and collagen fibers in choice D provides both hardness and flexibility, making bones resistant to shattering.
