TEAS Test 7 science quizlet
1. Identify the function NOT attributed to the lymphatic system.
- A. Fluid drainage from tissues
- B. Immune response via white blood cell production
- C. Nutrient transport throughout the body
- D. Waste removal through lymph nodes
Correct answer: C
Rationale: A) Fluid drainage from tissues: This function is attributed to the lymphatic system. Lymphatic vessels collect excess fluid from tissues and return it to the bloodstream. B) Immune response via white blood cell production: The lymphatic system plays a crucial role in the body's immune response by producing and transporting white blood cells, such as lymphocytes, which help fight infections. C) Nutrient transport throughout the body: Nutrient transport is primarily carried out by the circulatory system (blood vessels), not the lymphatic system. The circulatory system transports nutrients, oxygen, and hormones to cells and removes waste products. D) Waste removal through lymph nodes: The lymphatic system helps remove waste and toxins from the body by filtering lymph through lymph nodes, where harmful substances are trapped and destroyed by immune cells. Therefore, the function NOT attributed to the lymphatic system is C) Nutrient transport throughout the body.
2. What pigment is responsible for the yellow color of bananas?
- A. Potassium
- B. Calcium
- C. Phosphorus
- D. Carotene
Correct answer: D
Rationale: Carotene is the pigment responsible for the yellow color of bananas. It belongs to a group of plant pigments called carotenoids, which are responsible for giving fruits and vegetables their vibrant colors, including the yellow hue of bananas. Potassium, calcium, and phosphorus are essential minerals found in bananas but are not responsible for their yellow color.
3. Which organelle is responsible for the final stages of protein modification and packaging for secretion in animal cells?
- A. Rough endoplasmic reticulum (RER)
- B. Smooth endoplasmic reticulum (SER)
- C. Ribosomes
- D. Golgi apparatus
Correct answer: D
Rationale: The Golgi apparatus is responsible for the final stages of protein modification and packaging for secretion in animal cells. After proteins are synthesized in the rough endoplasmic reticulum (RER), they are transported to the Golgi apparatus for further processing, sorting, and packaging before being sent to their final destination within or outside the cell. The smooth endoplasmic reticulum (SER) is mainly involved in lipid metabolism and detoxification processes, not protein modification. Ribosomes are the cellular organelles responsible for protein synthesis, not the final stages of protein modification and packaging for secretion, which is the role of the Golgi apparatus.
4. A ball is rolling across the floor and comes to a stop on its own. What force caused the ball to stop?
- A. Gravitational force
- B. Normal force from the floor
- C. Air resistance
- D. None of the above
Correct answer: C
Rationale: The force that caused the ball to stop rolling across the floor is air resistance. As the ball moves through the air, air resistance acts in the opposite direction of its motion, gradually slowing it down until it comes to a stop. In this scenario, the ball is not in contact with the floor, so the normal force from the floor does not play a role in stopping the ball. Gravitational force acts to pull objects towards the center of the Earth and would not directly stop the ball in this situation. Therefore, air resistance is the force that opposes the motion of the rolling ball and causes it to come to a stop.
5. Tendonitis is an inflammation of which part of the body?
- A. Muscles
- B. Tendons
- C. Ligaments
- D. Cartilage
Correct answer: B
Rationale: Tendonitis specifically refers to the inflammation of tendons, which are the thick cords that connect muscles to bones. The correct answer is tendons. Choice A, muscles, are not affected in tendonitis, but rather in myositis, which is the inflammation of muscles. Ligaments (Choice C) connect bones to other bones, while cartilage (Choice D) is a smooth and flexible tissue that covers the ends of bones at a joint. Therefore, the correct term for inflammation of tendons is tendonitis.
