Reading

1. What can be inferred about the water management systems in Petra?

Correct answer: C

Rationale: The passage highlights the "elaborate" water systems, suggesting their complexity and importance.

2. The process of a gas changing into a liquid is called:

Correct answer: C

Rationale: Condensation happens when gas particles lose energy and slow down, transitioning into the liquid state.

3. What is the process of breaking down and rebuilding bone tissue called?

Correct answer: B

Rationale: The correct answer is B: Remodeling. Remodeling is the process of breaking down and rebuilding bone tissue. This process helps maintain bone strength and structure by replacing old or damaged bone with new bone. Ossification refers to the formation of bone tissue, not the breakdown and rebuilding process. Calcification is the deposition of calcium salts in tissues, not specifically related to bone tissue remodeling. Osteoporosis is a condition characterized by a decrease in bone density, but it is not the process of breaking down and rebuilding bone tissue.

4. Distinguish between the digestive and respiratory systems.

Correct answer: D

Rationale: Rationale: - The mouth, stomach, and small intestine are all parts of the digestive system, responsible for breaking down food into nutrients that can be absorbed by the body. - The lungs are part of the respiratory system, responsible for the exchange of oxygen and carbon dioxide between the body and the environment through breathing. - While the digestive system processes food for energy and nutrients, the respiratory system is focused on the exchange of gases necessary for cellular respiration.

5. Molecular clocks utilize the accumulation of mutations in DNA sequences to estimate the evolutionary divergence time between species. This method relies on the assumption that:

Correct answer: A

Rationale: Rationale: A molecular clock is a method used to estimate the time of divergence between species by measuring the accumulation of mutations in DNA sequences. This method relies on the assumption that mutations occur at a relatively constant rate over time. If the rate of mutation were not constant, it would be challenging to accurately estimate the evolutionary divergence time between species. Therefore, option A is the most appropriate choice as it aligns with the fundamental principle underlying the molecular clock hypothesis. Option B is incorrect because the assumption that species with more morphological similarities diverged more recently does not directly relate to the concept of molecular clocks and the accumulation of mutations in DNA sequences. Option C is incorrect because mutations are not always beneficial and do not always contribute to increased fitness. Mutations can be neutral or deleterious as well, and their accumulation is what is used to estimate evolutionary di

6. What is the term for the chemical reaction that involves the loss of electrons?

Correct answer: b

Rationale: Oxidation is the chemical reaction that involves the loss of electrons. The other choices describe different types of reactions.
