TEAS 7 science quizlet

1. Muscle tissue is responsible for movement. Which type of muscle tissue is found in the heart?

Correct answer: C

Rationale: Cardiac muscle is the type of muscle tissue found in the heart. Unlike skeletal muscle and smooth muscle, cardiac muscle is striated and involuntary, meaning it contracts without conscious control. It forms the majority of the heart's structure and is essential for its rhythmic contraction to pump blood throughout the body. Skeletal muscle is attached to bones and responsible for voluntary movements, while smooth muscle is found in organs and blood vessels, controlling various involuntary functions like digestion and blood flow. Therefore, choices A (Skeletal muscle) and B (Smooth muscle) are incorrect as they are not the types of muscle tissue found in the heart.

2. An FBI agent has spent her career studying individual serial killers. From this data, she creates a theory about the traits of these killers. What type of reasoning has she used?

Correct answer: D

Rationale: The correct answer is D: Inductive Reasoning. Inductive reasoning involves drawing a general conclusion from specific observations or data, which fits the scenario described where the FBI agent has studied individual serial killers and formulated a theory about their traits based on this specific data. Deductive reasoning (choice A) starts with general information and applies it to a specific case, which is not the case here. Conductive reasoning (choice B) and quantitative reasoning (choice C) are not relevant to the scenario provided.

3. What type of inheritance pattern results in a 3:1 ratio of dominant to recessive phenotypes in the F2 generation?

Correct answer: D

Rationale: Autosomal dominant inheritance results in a 3:1 ratio of dominant to recessive phenotypes in the F2 generation. This inheritance pattern occurs when a single copy of the dominant allele is enough to express the dominant phenotype. A) Incomplete dominance: In incomplete dominance, the heterozygous phenotype is a blend of the two homozygous phenotypes, and it does not lead to a 3:1 ratio of dominant to recessive phenotypes in the F2 generation. B) Codominance: In codominance, both alleles are fully expressed in the heterozygous phenotype, but this pattern also does not result in a 3:1 ratio of dominant to recessive phenotypes in the F2 generation. C) Sex-linked inheritance: Sex-linked inheritance involves genes located on the sex chromosomes and does not typically lead to a 3:1 ratio of dominant to recessive phenotypes in the F2 generation.

4. What are the four chambers of the heart?

Correct answer: A

Rationale: The correct answer is A: Right atrium, left atrium, right ventricle, left ventricle. The heart consists of four chambers: the right atrium, left atrium, right ventricle, and left ventricle. Blood flows from the body into the right atrium, then to the right ventricle, where it is pumped to the lungs for oxygenation. Oxygenated blood returns to the left atrium, passes to the left ventricle, and is then pumped out to the body. Choice B is incorrect because it incorrectly lists the left atrium twice. Choice C is incorrect as it rearranges the order of the chambers. Choice D is incorrect as it mistakenly switches the atria and ventricles in their positions.

5. What type of energy is stored in food?

Correct answer: C

Rationale: Food stores energy in the form of chemical potential energy. This energy is released during digestion and metabolism to provide the body with the energy it needs to function. It is derived from the bonds within the molecules of food, such as carbohydrates, fats, and proteins. Choice A, mechanical energy, is incorrect as food does not store energy in the form of mechanical energy. Choice B, kinetic energy, is incorrect as kinetic energy is associated with the motion of objects, not stored in food. Choice D, thermal energy, is incorrect as thermal energy relates to heat energy, which is not the primary form of energy stored in food.
