1. Which part of the neuron receives incoming signals from other neurons and conducts them toward the cell body?

Correct answer: b

Rationale: The correct answer is B: Dendrite. Dendrites are the part of the neuron that receive incoming signals from other neurons and conduct them toward the cell body. They play a crucial role in communication between neurons by receiving neurotransmitters released from neighboring neurons. Axons transmit signals away from the cell body, synapses are the junctions where neurons communicate with each other, and myelin sheath is a fatty insulation that surrounds and protects axons. Therefore, in this scenario, dendrites are specifically responsible for receiving and conducting incoming signals towards the cell body.

2. Which state of matter has both definite volume and definite shape?

Correct answer: a

Rationale: Solids have both definite volume and definite shape. The particles in solids are closely packed, maintaining their positions, resulting in a fixed shape and volume.

3. The element responsible for the yellow color of bananas is:

Correct answer: D

Rationale: Carotene is a type of carotenoid pigment found in fruits and vegetables, contributing to their yellow, orange, and red hues.

4. What is the term for the number of moles of solute per liter of solution?

Correct answer: A

Rationale: Molarity is defined as the number of moles of solute per liter of solution. The other choices are different concentration units.

5. What type of error occurs in the sentence "Everyone knew who the culprit was, except for me"?

Correct answer: B

Rationale: The phrase "except for me" modifies "everyone," but it is misplaced after the verb "knew," causing confusion.

6. What is the difference between type 1 and type 2 diabetes, both related to insulin and blood sugar?

Correct answer: A

Rationale: The correct answer is A: 'Type 1 is caused by insulin resistance, type 2 by insulin deficiency.' Type 1 diabetes is an autoimmune condition where the body attacks insulin-producing cells, leading to insulin deficiency. In contrast, type 2 diabetes occurs when the body becomes resistant to insulin's effects. This distinction is crucial for understanding the underlying causes and treatment approaches for each type of diabetes. Type 1 diabetes is not temporary; it is a chronic condition that requires lifelong management. Type 2 diabetes can also affect adults, but it is more commonly diagnosed in middle-aged and older adults. Treatment for type 1 diabetes typically involves insulin therapy along with diet and exercise, while type 2 diabetes may require medication in addition to lifestyle modifications.
