Anatomy

1. Dendrites are finger-like extensions found on

Correct answer: C

Rationale: Dendrites are the primary sites for receiving signals in a neuron. They are specialized extensions that branch out from the cell body of a neuron to receive incoming information from other neurons. These finger-like projections play a crucial role in transmitting electrical impulses and communication within the nervous system. Muscle cells, connective tissue cells, and epithelial cells do not have dendrites as they are not involved in neuronal communication.

2. Ms. Castro learns that some leaders are transactional leaders. Which of the following does

Correct answer: C

Rationale: The correct answer is C: 'Uses trade-offs to meet goals.' Transactional leaders focus on the exchange or transaction that occurs between them and their followers. They set clear expectations and goals for their followers and use rewards and punishments to motivate them. This approach involves making trade-offs to achieve desired outcomes, such as rewarding employees for meeting targets or penalizing them for not meeting expectations. Options A and B do not directly relate to transactional leadership, as it is more about goal achievement and motivation through rewards and punishments. Option D describes a transformational leader, who inspires and motivates others through a shared vision and values, which is different from the transactional leadership style described in the question.

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

Correct answer: C

Rationale: The correct answer is C: Cardiac muscle. Cardiac muscle is a specialized type of muscle tissue found in the heart. Unlike skeletal muscle, which is under voluntary control, and smooth muscle, which is found in the walls of internal organs and blood vessels, cardiac muscle is involuntary and responsible for the rhythmic contractions of the heart to pump blood throughout the body. Therefore, cardiac muscle is the specific type of muscle tissue found in the heart, making it the correct choice for this question.

4. The process by which a single-celled organism divides into two identical daughter cells is called

Correct answer: B

Rationale: Rationale: A) Conjugation is a process in which genetic material is transferred between two bacterial cells through a conjugation tube. It does not involve the division of a single-celled organism into two identical daughter cells. B) Binary fission is the process by which a single-celled organism, such as a bacterium, divides into two identical daughter cells. This is a common method of reproduction in prokaryotic organisms. C) Endocytosis is a cellular process in which cells engulf external materials by wrapping them in a vesicle. It is not a method of cell division. D) Mitosis is a type of cell division that occurs in eukaryotic cells, leading to the production of two daughter cells with identical genetic material. However, the question specifically refers to a single-celled organism, which typically undergoes binary fission for reproduction.

5. The scientist discovered a new species of butterfly in the rainforest. What is the past tense of the verb "discover"?

Correct answer: B

Rationale: The past tense of a verb describes an action that happened in the past.

6. The concept of punctuated equilibrium suggests that:

Correct answer: B

Rationale: Rationale: A) Evolution occurs gradually through the continuous accumulation of small changes over long periods - This statement describes the gradualism model of evolution, not punctuated equilibrium. Punctuated equilibrium suggests that evolution is characterized by long periods of little to no change (stasis) followed by relatively rapid bursts of evolutionary change. B) Evolution is characterized by long periods of relative stasis punctuated by rapid bursts of evolutionary change - This statement accurately describes the concept of punctuated equilibrium proposed by Stephen Jay Gould and Niles Eldredge. It suggests that species remain relatively unchanged for long periods of time, interrupted by sudden bursts of rapid evolution. C) The fossil record is a complete and accurate representation of all past life forms - This statement is incorrect as the fossil record is incomplete and biased towards certain types of organisms and environments. It does not provide a complete and accur
