1. Which of the following animals would have the least energy efficiency in nutrient consumption?

• A. Cow
• B. Caterpillar
• C. Coyote
• D. Cricket

Correct answer: A

Rationale: Cows are ruminant animals that have multiple stomachs and require large amounts of food to digest and convert into energy. They have lower energy efficiency compared to insects like caterpillars, coyotes, and crickets, which have more efficient nutrient consumption processes. The digestive system and metabolic functions of cows result in them having the least energy efficiency in nutrient consumption among the given choices. Caterpillars, coyotes, and crickets have more efficient nutrient consumption processes, making them more energy-efficient than cows.

2. What are the three types of muscle tissue?

• A. Cardiac, spinal, stomach
• B. Smooth, skeletal, cardiac
• C. Neuron, epithelial, collagen
• D. None of the above

Correct answer: B

Rationale: The correct answer is B: Smooth, skeletal, cardiac. Smooth muscle is found in organs like the stomach and is involuntarily controlled. Skeletal muscle is found in voluntary muscles, like the bicep or quadriceps. Cardiac muscle is found only in the heart walls and works involuntarily to make the heart beat and pump blood. Choices A, C, and D are incorrect because they do not represent the three types of muscle tissue.

3. Which organelle is found in protists but not in monerans?

• A. Golgi apparatus
• B. Chromosome
• C. Cytoplasm
• D. Cell membrane

Correct answer: A

Rationale: The Golgi apparatus is the correct answer. The Golgi apparatus is a cellular organelle responsible for processing and packaging proteins before they are transported to their final destination. Protists, being eukaryotic organisms, have membrane-bound organelles including the Golgi apparatus, which are absent in monerans. Monerans are prokaryotic organisms that lack membrane-bound structures such as the Golgi apparatus. Choices B, C, and D are incorrect as chromosomes, cytoplasm, and cell membranes are present in both protists and monerans.

4. What organelle is responsible for packaging, processing, and shipping?

• A. Nucleus
• B. Golgi Apparatus
• C. Endoplasmic Reticulum
• D. Ribosomes

Correct answer: B

Rationale: The Golgi Apparatus is the correct answer. It is responsible for packaging, processing, and shipping proteins and lipids within the cell. The nucleus houses genetic material, the endoplasmic reticulum is involved in protein synthesis and lipid metabolism, and ribosomes are responsible for protein synthesis. Therefore, choices A, C, and D are not the correct answers for the functions of packaging, processing, and shipping.

5. Which type of sugar is a disaccharide?

• A. Sucrose
• B. Fructose
• C. Glucose
• D. Galactose

Correct answer: A

Rationale: The correct answer is A, Sucrose. Sucrose is a disaccharide composed of one molecule of glucose and one molecule of fructose. When glucose and fructose combine, they form sucrose. Choice B, Fructose, is a monosaccharide, not a disaccharide. Choice C, Glucose, is also a monosaccharide, not a disaccharide. Choice D, Galactose, is another monosaccharide and not a disaccharide.
