TEAS Test 7 science quizlet
1. Which muscular tube carries urine from the kidneys to the bladder?
- A. Nephron
- B. Ureter
- C. Urethra
- D. Glomerulus
Correct answer: B
Rationale: The correct answer is B: Ureter. The ureter is the muscular tube that carries urine from the kidneys to the bladder. The nephron is the functional unit of the kidney responsible for filtering blood and producing urine. The urethra is the tube that carries urine from the bladder out of the body. The glomerulus is a network of capillaries in the nephron where filtration of blood occurs.
2. A car is accelerating down a hill. Which of the following forces is NOT acting on the car?
- A. Gravitational force
- B. Normal force from the road
- C. Air resistance
- D. The car's engine force
Correct answer: B
Rationale: When a car is accelerating down a hill, the normal force from the road is not acting on the car. The normal force is the force exerted by a surface to support the weight of an object resting on it. As the car moves downhill, the normal force decreases since the road is no longer pushing back against the car's weight due to the downhill motion. Gravitational force pulls the car downhill, air resistance opposes the car's motion, and the car's engine force propels it forward. Therefore, the correct answer is B, as the normal force from the road is not acting on the car while it accelerates downhill.
3. What is the end result of mitosis in animal cells?
- A. The production of two identical daughter cells
- B. The production of four haploid cells
- C. The production of a single diploid cell
- D. The production of a single haploid cell
Correct answer: A
Rationale: Mitosis is a type of cell division specific to eukaryotic cells that results in the production of two identical daughter cells, each with the same genetic material as the parent cell. This process is crucial for growth, tissue repair, and maintaining a constant number of chromosomes in multicellular organisms. During mitosis, the replicated chromosomes are segregated into two separate nuclei, followed by the division of the cell into two identical daughter cells. Options B, C, and D are incorrect as mitosis does not lead to the production of four haploid cells, a single diploid cell, or a single haploid cell. The correct answer is A because mitosis results in the formation of two daughter cells that are genetically identical to each other and to the parent cell, allowing for growth and replacement of damaged cells in multicellular organisms.
4. Which of the following systems does not include a transportation network throughout the body?
- A. Cardiovascular system
- B. Endocrine system
- C. Immune system
- D. Nervous system
Correct answer: B
Rationale: The endocrine system does not include a transportation network throughout the body. While the cardiovascular system transports blood, oxygen, and nutrients, the immune system has lymphatic vessels for immune cell transportation, and the nervous system transmits signals via neurons. In contrast, the endocrine system coordinates bodily functions by releasing hormones directly into the bloodstream, which then act on target organs or tissues. This delivery mechanism is different from the continuous transportation networks found in the other systems listed, making the endocrine system the correct choice for this question.
5. 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: A) Cellular respiration is the correct answer. It 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, it is not the process of converting glucose into ATP. D) Hydrolysis is a chemical process that uses water to break down molecules into smaller components. It is not specifically related to converting glucose into ATP.
