anatomy

1. Which part of the neuron insulates and speeds up the transmission of nerve impulses along the axon?

Correct answer: b

Rationale: The correct answer is B: Myelin sheath. The myelin sheath is a fatty substance that surrounds the axon of a neuron, acting as an insulator to speed up the transmission of nerve impulses. It does this by creating gaps called nodes of Ranvier where the nerve impulses jump from one node to the next, allowing for faster signal conduction. Dendrites are branch-like extensions that receive signals from other neurons, the synapse is the junction between two neurons where neurotransmitters are released, and the cell body contains the nucleus and organelles of the neuron, but it is the myelin sheath that specifically insulates and speeds up the transmission of nerve impulses along the axon.

2. Which of the following is a unit of measurement for energy?

Correct answer: b

Rationale: Energy is measured in Joules (J) in the SI unit system.

3. Which muscular pouch in the upper left abdomen stores food after swallowing and begins mechanical and chemical digestion?

Correct answer: B

Rationale: The correct answer is B: Stomach. The stomach is the muscular pouch in the upper left abdomen that stores food after swallowing. It is responsible for beginning both mechanical and chemical digestion processes. Once food enters the stomach, it is mixed with gastric juices and enzymes that break down the food into smaller particles. The stomach also contracts and relaxes to further mix the food with digestive juices. The esophagus is a tube that connects the throat to the stomach and does not store food or participate in digestion. The small intestine and large intestine are parts of the digestive system, but they are not muscular pouches in the upper left abdomen responsible for storing and digesting food.

4. Which word completes the sentence: "Despite the storm, the concert ____ went on."

Correct answer: D

Rationale: "Nonetheless" emphasizes the continuation of the concert despite the contrary circumstance.

5. Which sentence avoids a comma splice?

Correct answer: C

Rationale: Option C uses a semicolon to separate two independent clauses, avoiding a comma splice.

6. A kite has a top base of 20cm, a bottom base of 30cm, and two equal side lengths of 15cm. What is its perimeter?

Correct answer: C

Rationale: Add the lengths of all sides: perimeter = top base + bottom base + 2 * side length = 20cm + 30cm + 2 * 15cm = 70cm.
