1. The important decision will be made tomorrow. Which word is the comparative form of the adjective "important"?
- A. important
- B. importantly
- C. more important
- D. most important
Correct answer: C
Rationale: The comparative form of an adjective compares two things.
2. What is the scientific term for scar tissue?
- A. Epithelial tissue
- B. Fibrous connective tissue
- C. Cartilage
- D. Adipose tissue
Correct answer: B
Rationale: The correct answer is B: Fibrous connective tissue. Scar tissue is formed during the process of wound healing, where fibroblasts produce collagen fibers to repair damaged tissue. This results in the formation of fibrous connective tissue, which is different from epithelial tissue (A), cartilage (C), and adipose tissue (D). While epithelial tissue lines surfaces and organs, cartilage is a type of connective tissue found in joints, and adipose tissue is a type of connective tissue that stores energy in the form of fat. Scar tissue, on the other hand, is primarily composed of collagen fibers and is classified as fibrous connective tissue.
3. A collection of organs working together to perform a specific physiological function is known as a(n):
- A. Tissue
- B. Organ system
- C. Organelle
- D. Organ
Correct answer: B
Rationale: The correct answer is B: Organ system. An organ system is a group of organs that work together to carry out a specific function in the body. While an organ is made up of different types of tissues that work together, an organ system involves multiple organs collaborating to perform more complex tasks. Tissues (option A) are groups of similar cells working together, organelles (option C) are structures within cells that have specific functions, and organs (option D) are made up of tissues and perform specific functions, but the term 'organ system' specifically refers to a higher level of organization involving multiple organs working in coordination.
4. Vacuoles are large sacs for storage in plant cells. What is their main function in animal cells?
- A. Protein synthesis
- B. Waste storage and disposal
- C. Photosynthesis
- D. Cellular respiration
Correct answer: B
Rationale: Vacuoles in plant cells are primarily used for storage of water, nutrients, and waste products. In animal cells, vacuoles are smaller and serve various functions, including waste storage and disposal. Option B, 'Waste storage and disposal,' is the correct answer because vacuoles in animal cells help maintain cellular homeostasis by storing and breaking down waste materials. This process aids in detoxification and maintaining proper cellular function in animal cells, similar to the role of vacuoles in plant cells.
5. What is the term for a group of organisms with the same genetic makeup?
- A. Population
- B. Clone
- C. Genotype
- D. Species
Correct answer: B
Rationale: Rationale: - A population (option A) refers to a group of individuals of the same species living in the same area. - Genotype (option C) refers to the genetic makeup of an individual organism. - Species (option D) refers to a group of organisms that can interbreed and produce fertile offspring. In this context, a clone (option B) is a group of organisms that are genetically identical because they are derived from a single ancestor. This term specifically refers to organisms with the same genetic makeup, making it the most appropriate choice for the question.
6. What is a contraceptive method that uses hormones to prevent ovulation?
- A. Spermicide
- B. Barrier method (condom, diaphragm)
- C. Combined oral contraceptive pill
- D. Intrauterine device (IUD)
Correct answer: C
Rationale: The correct answer is C: Combined oral contraceptive pill. This method uses hormones, such as estrogen and progestin, to prevent ovulation, thicken cervical mucus to block sperm, and thin the uterine lining to prevent implantation of a fertilized egg. Spermicide (A) is a chemical that kills sperm but does not prevent ovulation. Barrier methods (B) like condoms and diaphragms physically block sperm from reaching the egg. Intrauterine devices (IUDs) (D) are inserted into the uterus and work by either releasing hormones or creating a barrier to prevent fertilization, but they do not specifically target ovulation.
