Reading

1. 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.

2. Which of the following is NOT a type of antibody?

Correct answer: C

Rationale: Rationale: A) IgA: This is a type of antibody found in mucosal areas such as the gut, respiratory tract, and genitourinary tract. B) IgM: This is a type of antibody produced during the primary immune response and is the first antibody to be produced in response to an infection. C) Interferon: Interferons are signaling proteins produced by cells in response to viral infections. They play a role in the immune response but are not antibodies. D) IgG: This is the most abundant type of antibody in the bloodstream and is involved in long-term immunity. Therefore, the correct answer is C) Interferon, as it is not a type of antibody.

3. What happens to the acceleration of an object when the force acting on it is increased, assuming the mass remains constant?

Correct answer: a

Rationale: According to Newton's second law (F = ma), if mass is constant and force increases, acceleration also increases.

4. The rigid structure that provides shape and support to plant cells is called the:

Correct answer: A

Rationale: The correct answer is A: Cell wall. The cell wall is a rigid structure found in plant cells, providing support and shape to the cell. It is composed mainly of cellulose, a tough and fibrous substance that helps plants maintain their structure. The plasma membrane, option B, is a semi-permeable membrane that surrounds the cell and regulates the passage of substances in and out of the cell. The nucleus, option C, is the control center of the cell that contains genetic material. Cytoplasm, option D, is the jelly-like substance that fills the cell and houses organelles. In this context, the function of providing shape and support points specifically to the cell wall, making it the correct choice.

5. Autoimmune diseases occur when the immune system mistakenly attacks healthy body tissues. What is a potential cause of autoimmune diseases?

Correct answer: C

Rationale: The correct answer is C. Autoimmune diseases are triggered by a breakdown in immune cell self-tolerance mechanisms, where the immune system fails to recognize 'self' from 'non-self' cells, leading to attacks on healthy tissues. While deficiencies in essential vitamins and minerals or exposure to environmental toxins can impact immune function, the root cause of autoimmune diseases is primarily attributed to the breakdown in self-tolerance mechanisms. This breakdown can be influenced by genetic predisposition, environmental factors, and other triggers, leading to the development of autoimmune conditions.

6. Electrons occupy specific energy levels around the nucleus with varying probabilities. The electron cloud model depicts electrons existing in distinct energy levels, not fixed orbits, with probabilities of finding them in specific regions.

Correct answer: B

Rationale: 2 filled s orbitals and 6 filled p orbitals. This notation indicates two electrons in the 2s orbital and six electrons in the 2p orbitals.
