TEAS Test 7 science quizlet Questions
Question 1 of 5
What is the primary function of the stomach?
Correct Answer: A
Rationale: The main function of the stomach is to store food, churn it, and break it down into smaller pieces through mechanical digestion. This process is facilitated by the mixing of food with gastric juices, including stomach acid. The mechanical breakdown in the stomach helps initiate the digestion of food before it progresses to the small intestine for further digestion and nutrient absorption. Absorption of nutrients into the bloodstream primarily occurs in the small intestine, not the stomach. Enzymes that aid in digesting food are primarily produced in the pancreas and small intestine, not in the stomach. The elimination of waste products from the body mainly occurs through the large intestine and rectum, not the stomach.
Question 2 of 5
What is a condition characterized by an overactive thyroid gland and excessive production of thyroid hormones called?
Correct Answer: B
Rationale: Hyperthyroidism is a condition where the thyroid gland is overactive and produces an excessive amount of thyroid hormones. This can lead to symptoms such as weight loss, rapid heartbeat, sweating, and nervousness. Diabetes mellitus is a condition characterized by high blood sugar levels due to either insufficient insulin production or the body's inability to respond to insulin. Hypothyroidism is the opposite of hyperthyroidism, where the thyroid gland is underactive and produces insufficient thyroid hormones. Cushing's syndrome is a disorder that occurs when the body has a high level of the hormone cortisol for a long time.
Question 3 of 5
Which organelle is responsible for carrying out photosynthesis in plant cells?
Correct Answer: C
Rationale: A) Golgi apparatus: The Golgi apparatus is responsible for modifying, sorting, and packaging proteins for secretion or for use within the cell. It is not involved in photosynthesis. B) Mitochondria: Mitochondria are known as the powerhouse of the cell and are responsible for generating energy in the form of ATP through cellular respiration. They are not involved in photosynthesis. C) Chloroplasts: Chloroplasts are the organelles responsible for carrying out photosynthesis in plant cells. They contain chlorophyll, a pigment that captures light energy and converts it into chemical energy in the form of glucose. D) Lysosomes: Lysosomes are membrane-bound organelles that contain digestive enzymes to break down waste materials and cellular debris. They are not involved in photosynthesis. Therefore, the correct answer is C) Chloroplasts, as they are specifically responsible for carrying out photosynthesis in plant
Question 4 of 5
Which of the following nutrients is essential for muscle growth and repair?
Correct Answer: B
Rationale: Protein is essential for muscle growth and repair as it provides the necessary building blocks (amino acids) for muscle tissue synthesis and repair. While vitamins and minerals are crucial for overall health, protein has a specific role in muscle development. Carbohydrates supply energy for workouts, and fats are important for general health but are less directly involved in muscle growth and repair compared to protein.
Question 5 of 5
A ball is rolling across the floor and comes to a stop on its own. What force caused the ball to stop?
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.
