1. What is the process of cells dividing to produce new cells called?

Correct answer: A

Rationale: Rationale: A) Cell division is the process by which a parent cell divides into two or more daughter cells, allowing for growth, repair, and reproduction in living organisms. This process ensures that genetic material is accurately passed on to the new cells. B) Cell differentiation refers to the process by which cells become specialized to perform specific functions in an organism. While cell division is essential for cell differentiation, they are distinct processes. C) Cell growth is the increase in size or mass of a cell, which can occur before or after cell division. While cell growth is a component of the cell division process, it is not the primary process of cells dividing to produce new cells. D) Cell regeneration is the process by which damaged or lost cells are replaced by new cells. While cell division is involved in cell regeneration, it specifically refers to the overall process of cells dividing to produce new cells. Therefore, the most appropriate answer to the ques

2. Nervous tissue is responsible for

Correct answer: C

Rationale: Nervous tissue is responsible for communication and coordination within the body. This tissue includes neurons and supporting cells, which work together to transmit electrical signals and information throughout the body. Movement is primarily controlled by the muscular system, protection is the role of the immune system and skin, while nutrient transport is primarily handled by the circulatory system. Therefore, the correct answer is C: 'Communication and coordination.'

3. What can be inferred about the water management systems in Petra?

Correct answer: C

Rationale: The passage highlights the "elaborate" water systems, suggesting their complexity and importance.

4. Which of the following is a risk factor for developing kidney stones?

Correct answer: C

Rationale: Having a family history of kidney stones is a risk factor for developing them because genetics play a role in kidney stone formation. Individuals with a family history are more likely to inherit genetic factors that increase the likelihood of developing kidney stones. While consuming a diet rich in fruits and vegetables, maintaining adequate hydration with water, and regularly engaging in moderate exercise are generally healthy habits that can help prevent kidney stones, they are not direct risk factors for developing them. Therefore, option C, having a family history of kidney stones, is the correct answer.

5. The number of protons in the nucleus of an atom determines its:

Correct answer: B

Rationale: The atomic number (Z) equals the number of protons in the nucleus and uniquely identifies an element. Mass number (A) includes both protons and neutrons, isotopes have different neutron numbers, and valence electrons are involved in bonding, not atomic identity.

6. The muscular tube that connects the mouth to the stomach is called the:

Correct answer: B

Rationale: The correct answer is B: Esophagus. The esophagus is the muscular tube that connects the mouth to the stomach. It plays a crucial role in transporting food from the mouth to the stomach through peristaltic movements. The pharynx is the part of the throat that connects the mouth and nasal cavity to the esophagus and trachea. The trachea, also known as the windpipe, is responsible for carrying air to and from the lungs. The larynx, commonly known as the voice box, is involved in producing sound and protecting the trachea during swallowing. Therefore, the esophagus is specifically responsible for food transport from the mouth to the stomach.
