1. What is the process of converting glucose into ATP, the cell's primary energy currency, called?

• A. Cellular respiration
• B. Fermentation
• C. Photosynthesis
• D. Hydrolysis

Correct answer: A

Rationale: Rationale: A) Cellular respiration is the process by which cells convert glucose into ATP, the primary energy currency of the cell. This process involves a series of biochemical reactions that occur in the mitochondria of eukaryotic cells or the cytoplasm of prokaryotic cells. Through cellular respiration, the energy stored in glucose molecules is gradually released and captured in the form of ATP. B) Fermentation is an anaerobic process that occurs in the absence of oxygen. It involves the partial breakdown of glucose to produce ATP and end products such as lactic acid or ethanol. While fermentation can generate ATP, it is less efficient than cellular respiration in terms of energy production. C) Photosynthesis is the process by which plants, algae, and some bacteria convert light energy into chemical energy in the form of glucose. This process occurs in chloroplasts and is the opposite of cellular respiration. While photosynthesis produces glucose,

2. How does an increase in mass affect the force required to produce the same acceleration on an object?

• A. Increases force required
• B. Decreases force required
• C. Has no effect on force required
• D. Causes unpredictable changes in force required

Correct answer: a

Rationale: With an increase in mass, more force is needed to produce the same acceleration due to inertia.

3. Which type of nutrient requires the most complex and lengthy digestion process?

• A. Carbohydrates
• B. Proteins
• C. Fats
• D. Vitamins

Correct answer: B

Rationale: Rationale: Proteins require the most complex and lengthy digestion process among the options provided. When we consume proteins, they need to be broken down into amino acids, which are the building blocks of proteins. This process starts in the stomach with the help of stomach acid and enzymes, continues in the small intestine where more enzymes break down proteins into amino acids, and finally, these amino acids are absorbed into the bloodstream for various bodily functions. Carbohydrates and fats also require digestion, but the process for breaking down proteins into amino acids is more complex and time-consuming. Vitamins, on the other hand, do not require digestion in the same way as proteins, carbohydrates, and fats, as they are already in a form that can be readily absorbed by the body.

4. Acids are generally characterized by a sour taste and the ability to:

• A. Turn litmus paper blue
• B. Conduct electricity in solution
• C. Neutralize bases
• D. React explosively with metals

Correct answer: B

Rationale: Acids release hydrogen ions (H+) in solution, allowing electrical conductivity

5. How many bones are there in the adult human skeleton?

• A. 126
• B. 206
• C. 300
• D. 525

Correct answer: D

Rationale: The correct answer is D: 525. The adult human skeleton consists of 206 bones. However, when accounting for individual bones, many of them are paired (like the ribs and vertebrae), bringing the total count to 206 individual bones but 525 in total when considering pairs. This includes bones in the skull, spine, ribs, arms, hands, pelvis, legs, and feet. So, while there are 206 individual bones, the total number of bones in the adult human skeleton is 525 when considering pairs.

6. 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.
