TEAS 7 science quizlet Questions

Question 1 of 5

How is power related to time?

Correct Answer: C

Rationale: Power is a measure of how quickly work is done or energy is transferred. It is defined as the rate at which work is done or energy is transferred. Power is not directly or inversely proportional to time, as it depends on the amount of work done or energy transferred, not the duration over which it is done. The relationship between power and time is not a direct one, so power is unrelated to time. Choice A and B are incorrect because power's relationship with time is not one of direct or inverse proportionality. Choice D is incorrect because power is not simply the product of time and work; it is the rate at which work is done or energy is transferred, which can vary independently of time.

Question 2 of 5

What is the term for a group of organisms that can interbreed and produce fertile offspring?

Correct Answer: D

Rationale: A species is defined as a group of organisms that can interbreed and produce fertile offspring, which is a fundamental concept in biology. This ability to interbreed and produce fertile offspring is a key characteristic that distinguishes one species from another. Genus (option A) refers to a taxonomic rank that includes one or more closely related species, not the ability to interbreed. Phylum (option B) and kingdom (option C) are higher taxonomic ranks that encompass a broader range of organisms, not specifically defined by interbreeding and fertile offspring production. Therefore, the correct answer is 'Species.'

Question 3 of 5

Vacuoles are large sacs for storage in plant cells. What is their main function in animal cells?

Correct Answer: B

Rationale: Vacuoles in animal cells primarily function in waste storage and disposal, helping to maintain cellular homeostasis by storing waste products and aiding in their removal from the cell. Unlike plant cells, animal cells do not typically use vacuoles for storage purposes such as water, nutrients, or pigments. Instead, animal cells rely on other organelles like lysosomes for waste management and maintaining cellular balance. Choices A, C, and D are incorrect because protein synthesis occurs in ribosomes, photosynthesis takes place in chloroplasts (absent in animal cells), and cellular respiration mainly occurs in mitochondria, respectively. Vacuoles in animal cells serve a different purpose compared to plant cells.

Question 4 of 5

Which hormone is responsible for regulating blood sugar levels and is produced by the pancreas?

Correct Answer: A

Rationale: Insulin is the correct answer. It is the hormone produced by the pancreas that regulates blood sugar levels by facilitating the uptake of glucose from the blood into cells for energy production or storage. Glucagon, also produced by the pancreas, has the opposite effect of increasing blood sugar levels by promoting the release of stored glucose from the liver. Testosterone and estrogen are sex hormones produced by the testes and ovaries, respectively, and are not directly involved in regulating blood sugar levels.

Question 5 of 5

Identify the element with the electron configuration: 1s2 2s2 2p6 3s2 3p6. To which group and period does this element belong?

Correct Answer: C

Rationale: The given electron configuration matches that of Argon, an element found in Group 18 of the periodic table. This element is in the third period, as indicated by the highest energy level (n=3) where electrons are present. Therefore, the correct answer is Group 18, Period 3. Choice A (Group 16, Period 3) corresponds to sulfur, not the given electron configuration. Choice B (Group 14, Period 3) corresponds to silicon, not the given electron configuration. Choice D (Group 17, Period 2) corresponds to chlorine, which is in Period 3 but not in Group 18, making it incorrect for the given electron configuration.
