1. In the process of cellular respiration, glucose is broken down to produce energy. What is the main waste product released?

A. Water
B. Carbon dioxide
C. Oxygen
D. Protein

Correct answer: B

Rationale: The correct answer is B: Carbon dioxide. During cellular respiration, glucose is broken down in the presence of oxygen to produce energy in the form of ATP. One of the main waste products released in this process is carbon dioxide. Carbon dioxide is a byproduct of the metabolic reactions occurring in cells and is expelled from the body through exhalation. Water is also produced during cellular respiration, but it is not the main waste product released. Oxygen is required for cellular respiration to occur, and protein is a macromolecule and not a waste product of cellular respiration.

2. What happens to the kinetic energy of an object when its velocity is doubled?

A. Kinetic energy remains the same
B. Kinetic energy is halved
C. Kinetic energy doubles
D. Kinetic energy quadruples

Correct answer: c

Rationale: Kinetic energy is directly proportional to the square of an object's velocity.

3. Which of the following is NOT a characteristic of living organisms?

A. Made up of cells
B. Able to reproduce
C. Require energy
D. Non-motile

Correct answer: D

Rationale: Rationale: A) Made up of cells: All living organisms are composed of one or more cells. This is a fundamental characteristic of life as defined by cell theory. B) Able to reproduce: One of the key characteristics of living organisms is their ability to reproduce and pass on genetic information to offspring. C) Require energy: Living organisms require energy to carry out various life processes such as growth, reproduction, and maintenance of homeostasis. This energy is obtained through processes like metabolism. D) Non-motile: While some living organisms may be non-motile (unable to move on their own), movement is a common characteristic of many living organisms. Motility allows organisms to respond to their environment, find food, escape predators, and carry out other essential activities.

4. What is the meaning of the phrase "to be on the same page"?

A. To be physically close
B. To agree or understand each other
C. To be sharing the same goal
D. To be facing the same direction

Correct answer: B

Rationale: The phrase means to be in agreement or share the same understanding.

5. The process by which an organism adapts to its environment through inherited traits is known as

A. Acclimatization
B. Behavioral ecology
C. Natural selection
D. Niche partitioning

Correct answer: C

Rationale: Rationale: A) Acclimatization refers to the short-term physiological adjustments an individual organism makes in response to changes in its environment. This process is reversible and does not involve inherited traits. B) Behavioral ecology is the study of how behavior contributes to an organism's survival and reproduction in its environment. While behavior can be influenced by natural selection, it is not the process by which an organism adapts through inherited traits. C) Natural selection is the process by which organisms with advantageous traits for their environment are more likely to survive, reproduce, and pass on those traits to their offspring. Over time, this leads to the adaptation of populations to their environments. D) Niche partitioning is the process by which species divide resources to reduce competition within an ecosystem. While this can influence the evolution of species, it is not the process by which an organism adapts through inherited traits.
