1. Which of the following are examples of positive correlation?

• A. As rainfall increases, plant stem length decreases.
• B. As rainfall increases, roots show longer length.
• C. When plotting a comparison of rainfall to plant length, the line trends to the lower right.
• D. When plotting a comparison of rainfall to plant length, the line trends to the upper right.

Correct answer: D

Rationale: The correct answer is D. Positive correlation indicates that as one variable increases, the other variable also increases. In this case, when plotting a comparison of rainfall to plant length, if the line trends to the upper right, it shows a positive correlation where as rainfall increases, plant length also increases. Choices A, B, and C show either no correlation or negative correlation, as they describe scenarios where the variables move in different or opposite directions.

2. Which of the following best describes a balanced force acting on an object?

• A. The object remains at rest
• B. The object moves with constant velocity
• C. The object accelerates
• D. The object's mass changes

Correct answer: B

Rationale: When a balanced force acts on an object, the net force is zero, resulting in no acceleration. This means that the object will continue to move with a constant velocity if it was already in motion or remain at rest if it was initially stationary. Choice A is incorrect because the object can also move with constant velocity. Choice C is incorrect as acceleration only occurs when an unbalanced force is applied. Choice D is incorrect as the mass of an object is not affected by the balance of forces acting on it.

3. Based on the author's support and evidence, which of the following is a valid evaluation of the paragraph?

• A. It is an entertaining piece based on personal opinion.
• B. It is part of a historical account of the Great Emu War in Australia.
• C. It is a detailed analysis of military strategies during the Great Emu War.
• D. It is a scientific report on the impact of emus on the Australian ecosystem.

Correct answer: B

Rationale: The paragraph provides a historical account of the Great Emu War in Australia, outlining the events, dates, and outcomes of the conflict between the Australian government and the emu population. It does not focus on personal opinion, military strategies, or the scientific impact of emus, making choice B the most accurate evaluation. Choices A, C, and D are incorrect as they do not align with the content of the paragraph.

4. Which of the following organs is NOT directly involved in urine production?

• A. Kidneys
• B. Urethra
• C. Lungs
• D. Bladder

Correct answer: B

Rationale: The correct answer is B, Urethra. The urethra is not directly involved in urine production. It is a tube that carries urine from the bladder to the outside of the body. The kidneys are responsible for filtering waste and excess substances from the blood to produce urine. The bladder stores urine until it is expelled from the body. The lungs are not involved in urine production; they are responsible for gas exchange during respiration. Choice A, Kidneys, is directly involved in urine production by filtering the blood to form urine. Choice C, Lungs, plays a role in respiration and oxygen exchange but is not directly involved in urine production. Choice D, Bladder, stores urine before it is excreted from the body and is directly involved in the final stages of urine elimination, unlike the urethra.

5. What are groups of cells that perform the same function called?

• A. tissues
• B. plastids
• C. organs
• D. molecules

Correct answer: A

Rationale: Groups of cells that perform the same function are called tissues. Tissues are composed of a group of similar cells working together to carry out specific functions within an organism. Each type of tissue has a specialized structure that enables it to perform its specific role effectively. Plastids are cell organelles found in plants responsible for functions like photosynthesis and storage, not groups of cells. Organs are composed of different types of tissues working together. Molecules are made up of atoms and are not groups of cells.
