1. Which of the following lists Julia’s actions in the correct sequence?

• A. Julia woke up early and found she didn’t have any regular coffee. When she got to work, her boss had a lot for her to do. When the fire alarm went off, she decided to go home.
• B. Julia got to work and decided she was too tired to do the work her boss asked for, so she went home to get a cup of coffee.
• C. Julia woke up when the fire alarm went off and couldn’t get back to sleep. She then got stuck in traffic and arrived at work thirty minutes late.
• D. Julia was woken up early by a lawnmower and then got stuck in traffic on the way to her office. Once there, she found that the office was out of coffee and she had a lot of work to do. When the fire alarm went off, she decided to go home.

Correct answer: D

Rationale: Option D provides a sequence of events that align with the extract provided. Julia was woken up early by a lawnmower, couldn't go back to sleep, discovered she was out of regular coffee, got stuck in traffic on the way to work, found the office was out of coffee, had a lot of work to do, and decided to go home when the fire alarm went off. This sequence accurately reflects the chronological order of Julia's actions throughout the day. Choices A, B, and C do not follow a logical sequence of events based on the extract, making them incorrect.

2. Which of the following Mendelian laws describes how pairs of alleles within genes separate and recombine independently from other genes?

• A. law of segregation
• B. law of dominance
• C. law of independent assortment
• D. law of predictive traits

Correct answer: C

Rationale: The law of independent assortment describes how alleles of different genes segregate independently during gamete formation. This means that different gene pairs are passed on to offspring separately from one another, allowing for various combinations of traits. Gregor Mendel discovered this law, along with the law of segregation and the law of dominance, through his experiments with pea plants. The law of segregation (choice A) refers to how alleles of a gene separate during gamete formation, while the law of dominance (choice B) states that one allele can mask the presence of another in a heterozygous individual. The 'law of predictive traits' (choice D) is not a recognized Mendelian law and does not accurately describe the principles of genetic inheritance.

3. Which of the following nucleobases does not exist in RNA?

• A. Uracil
• B. Thymine
• C. Cytosine
• D. Guanine

Correct answer: B

Rationale: The correct answer is 'B: Thymine'. Thymine is a nucleobase found in DNA but is replaced by uracil in RNA. RNA contains Uracil, Cytosine, and Guanine as its nucleobases. Cytosine and Guanine are present in both DNA and RNA, while Thymine is exclusive to DNA and Uracil is specific to RNA.

4. What is the scientific term for a broken bone?

• A. Osteoporosis
• B. Fracture
• C. Sprain
• D. Dislocation

Correct answer: B

Rationale: The scientific term for a broken bone is a fracture. Osteoporosis is a condition characterized by weak and brittle bones, not a broken bone. A sprain involves an injury to a ligament, not a bone. Dislocation occurs when the ends of bones are forced out of their normal positions at a joint, which is different from a fracture.

5. Which of the following systems does not include a transportation network throughout the body?

• A. Cardiovascular system
• B. Endocrine system
• C. Immune system
• D. Nervous system

Correct answer: B

Rationale: The endocrine system does not include a transportation network throughout the body. While the cardiovascular system transports blood, oxygen, and nutrients, the immune system has lymphatic vessels for immune cell transportation, and the nervous system transmits signals via neurons. In contrast, the endocrine system coordinates bodily functions by releasing hormones directly into the bloodstream, which then act on target organs or tissues. This delivery mechanism is different from the continuous transportation networks found in the other systems listed, making the endocrine system the correct choice for this question.
