TEAS Test 7 science quizlet

1. Which organelle is responsible for cellular respiration, producing ATP for energy?

Correct answer: B

Rationale: The correct answer is B) Mitochondria. Mitochondria are known as the powerhouse of the cell because they are responsible for cellular respiration, a process that produces ATP (adenosine triphosphate) for energy. The other organelles listed, such as the nucleus, Golgi apparatus, and vacuole, have distinct functions within the cell and are not directly involved in cellular respiration. The nucleus contains genetic material, the Golgi apparatus is involved in protein processing and packaging, and the vacuole is responsible for storage and maintaining cell turgor pressure.

2. What is the structure that attaches to each chromosome during mitosis?

Correct answer: A

Rationale: The correct answer is the centromere. It is the structure that attaches to each chromosome during mitosis. The centromere serves as the attachment point for spindle fibers during cell division, ensuring proper distribution of chromosomes to daughter cells. Telomeres are found at the ends of chromosomes, providing protection and stability. The spindle apparatus is responsible for separating chromosomes during cell division. The nucleolus, located within the nucleus, is involved in ribosomal RNA synthesis and not in chromosome attachment during mitosis.

3. Which type of blood vessel carries oxygenated blood away from the heart?

Correct answer: B

Rationale: The correct answer is B. Arteries carry oxygenated blood away from the heart to the rest of the body, delivering nutrients and oxygen to the tissues. Veins, on the other hand, carry deoxygenated blood back to the heart. Capillaries are where the exchange of gases, nutrients, and waste products occurs between the blood and tissues. Lymphatic vessels are responsible for transporting lymph, which is a clear fluid containing white blood cells and waste products, and play a key role in the immune system.

4. What is cystitis an inflammation of?

Correct answer: B

Rationale: Cystitis is an inflammation of the bladder. It is typically caused by a bacterial infection and can lead to symptoms such as frequent urination, pain or burning during urination, and lower abdominal discomfort. The inflammation specifically affects the bladder lining. Choices A, C, and D are incorrect. Kidneys are not the site of inflammation in cystitis; they are associated with conditions like pyelonephritis. Ureters are tubes that connect the kidneys to the bladder, and the urethra is the tube that carries urine from the bladder to outside the body. Therefore, the correct answer is 'Bladder.'

5. What phenomenon occurs when two identical waves are perfectly aligned and reinforce each other?

Correct answer: D

Rationale: Constructive interference occurs when two identical waves are perfectly aligned and reinforce each other. This results in an increase in the overall amplitude of the wave. Refraction refers to the bending of waves as they pass from one medium to another, reflection is the bouncing back of waves when they encounter a boundary, and diffraction is the bending of waves around obstacles and openings. In this scenario, the waves are not changing direction or bending but rather combining to produce a wave with a larger amplitude, which is characteristic of constructive interference.
