1. What is the scientific study of the relationships between organisms and their environment?

Correct answer: C

Rationale: Ecology is the scientific study of the relationships between organisms and their environment, including the interactions between living organisms and their physical surroundings. This field focuses on how organisms interact with each other and their environment. Zoology is the study of animals, Botany is the study of plants, and Genetics is the study of genes and heredity, which are not directly related to the relationships between organisms and their environment. Therefore, the correct answer is Ecology as it specifically deals with the interactions between living organisms and their environment.

2. What is the primary function of the respiratory system?

Correct answer: B

Rationale: The primary function of the respiratory system is to take oxygen into the body through inhalation and remove carbon dioxide through exhalation. Oxygen is essential for cellular respiration and energy production, while carbon dioxide is a waste product that needs to be expelled from the body. This process is vital for the functioning of the body's cells and tissues. Choices A, C, and D are incorrect because sound and speech production, nutrient transport, and acting as a barrier against outside influences are not the primary functions of the respiratory system. While the respiratory system is involved in speech production to some extent, its primary role is in gas exchange for respiration.

3. Which of the following sentences is correct?

Correct answer: C

Rationale: Choice C is the correct answer because it properly uses quotation marks to indicate a direct quote within the sentence ('My history presentation was great!'). Choices A, B, and D contain direct quotes but fail to use quotation marks, making them incorrect. In choice A, the direct question 'How was your day?' should be enclosed in quotation marks. In choice B, the direct quote 'It was awesome.' should also be enclosed in quotation marks. In choice D, the direct statement 'That's wonderful!' should be enclosed in quotation marks.

4. Which statement most accurately compares and contrasts the structures of DNA and RNA?

Correct answer: A

Rationale: The correct answer is A because DNA and RNA both consist of 4 nucleotide bases, namely adenine, cytosine, and guanine, which are common in both. The key difference lies in the fourth base, which is thymine in DNA and uracil in RNA. This distinction is fundamental in understanding the structural variances between DNA and RNA. Choice B is incorrect as it incorrectly states that the nucleotides bond differently in DNA compared to RNA without specifying the crucial base differences. Choice C is inaccurate as it misrepresents the numbers of nucleotide bases in DNA and RNA, and incorrectly describes DNA as a double helix and RNA as a single strand, which is not related to the difference in bases. Choice D is incorrect as it inaccurately portrays DNA with 6 nucleotide bases and RNA with 4, which is not true; both DNA and RNA have 4 nucleotide bases, but with differences in one of the bases.

5. What are the tiny contractile units within muscle cells called?

Correct answer: C

Rationale: Sarcomeres are the smallest contractile units within muscle cells. They consist of overlapping filaments of actin and myosin proteins, which interact to produce muscle contractions. Myocytes are the entire muscle cells, myofibrils are bundles of protein filaments found within muscle cells, and tendons are tough connective tissues that connect muscles to bones. Therefore, sarcomeres specifically represent the contractile units responsible for muscle contraction, making them the correct answer in this context.
