1. The orthopedic surgeon informs you that you have broken the middle region of the humerus. What area is he describing?

Correct answer: D

Rationale: The diaphysis is the correct answer in this scenario. It refers to the middle or shaft region of a long bone like the humerus. The epiphysis is the end of a long bone, while articular cartilage is the smooth tissue covering the ends of bones at a joint. The perichondrium is the dense irregular connective tissue that surrounds cartilage.

2. The number of people _____ from other counties to the United States has caused a shift in unemployment in the textile market.

Correct answer: B

Rationale: The correct answer is 'Immigrating' because it refers to people coming to live permanently in a foreign country. 'Emigrating' (Choice A) means leaving one's own country to settle permanently in another, which does not fit the context of people coming into the United States. 'Migrating' (Choice C) is a general term for moving from one place to another without emphasizing the aspect of settling in a new country. 'Emigrated' (Choice D) is the past tense of emigrate and does not convey the ongoing action of people moving to the United States.

3. What is the process of cell division that results in two daughter cells with identical genetic material?

Correct answer: A

Rationale: The correct answer is A, Mitosis. Mitosis is the process of cell division in which a cell divides and produces two daughter cells that are genetically identical to the parent cell. Choice B, Meiosis, is a type of cell division that produces gametes with half the number of chromosomes. Choice C, Binary Fission, is a form of asexual reproduction in single-celled organisms. Choice D, Budding, is a form of asexual reproduction where a new organism develops from an outgrowth or bud on the parent.

4. After putting ⅓ aside for her share of rent and utilities and spending $75 on groceries, what is left from her weekly paycheck?

Correct answer: A

Rationale: If she puts aside 1/3 of her paycheck for rent and utilities, this means she spends 3 portions in total. So, 1 portion represents 1/3 of the paycheck. Since she spends $75 on groceries, it leaves 2 portions. The total amount of 3 portions is the paycheck. To find out one portion, divide the total paycheck by 3: Paycheck = 3 portions. $75 is one portion. Multiply the one portion by 3 to find the total paycheck: $75 * 3 = $225. Subtract the spent amount from the weekly paycheck: $225 - $75 = $150. Therefore, the amount left from her weekly paycheck is $150. The other choices are incorrect because they do not follow the correct calculation based on the given information.

5. The phases of mitosis include:

Correct answer: C

Rationale: The correct phases of mitosis are prophase, prometaphase, metaphase, anaphase, and telophase. Prophase is the first phase where chromatin condenses into chromosomes, the nuclear envelope breaks down, and the mitotic spindle forms. Prometaphase follows prophase, involving the full disintegration of the nuclear envelope and the attachment of spindle fibers to the kinetochores of the chromosomes. Metaphase is where chromosomes align along the metaphase plate. Anaphase is the phase where sister chromatids separate and move towards opposite poles. Telophase marks the final stage of mitosis, involving the decondensation of chromosomes and the reformation of the nuclear envelope. Choice A is incorrect because it includes interphase, which is not a phase of mitosis. Choice B is incorrect as it repeats prophase, which is the initial phase. Choice D is incorrect because it includes interphase and repeats prophase.
