Correct Answer: A. Adjectival phrase

Correct Answer: C. forgiveness would demonstrate Christian love

Correct Answer: D. the law and the prophets

Explanation

Paul says, But now the righteousness of God has been manifested apart from the law, although the Law and the Prophets bear witness to it . See romance3 :21 - 31

Correct Answer: C. Derived demand

Correct Answer: C. 13 protons and 14 neutrons

Explanation

Here's how to determine the composition of the nucleus:

1. Atomic Number (Z): This tells us the number of protons in the nucleus.

Given: Atomic number = 13

Therefore, the atom has 13 protons.

2. Mass Number (A): This tells us the total number of protons and neutrons in the nucleus.

Given: Mass of an element (mass number) = 27

The relationship is A = Z + N (where N is the number of neutrons).

3. Number of Neutrons (N): We can find the number of neutrons by subtracting the atomic number from the mass number.

N = A - Z

N = 27 - 13

N = 14 neutrons

4. Electrons: Electrons orbit the nucleus and are *not* part of the nucleus itself. The question specifically asks for the composition *of the nucleus*.

Therefore, the nucleus of this atom is composed of 13 protons and 14 neutrons.

Let's check the options:

A. 13 electrons and 14 protons - Incorrect (electrons are not in the nucleus).

B. 13 neutrons and 14 protons - Incorrect (the numbers are swapped compared to our calculation: 13 protons, 14 neutrons).

C. 13 protons and 14 neutrons - Correct.

D. 13 electrons and 14 neutrons - Incorrect (electrons are not in the nucleus).

The final answer is C

Correct Answer: A. Sex-linked traits are located on the sex chromosomes

Correct Answer: D) +5

Correct Answer: C. Gas molecules colliding in a flask

Explanation

The correct answer is C. Gas molecules colliding in a flask.

• Random motion (often associated with Brownian motion) refers to a movement where particles travel in unpredictable, zig-zag paths in all directions at various speeds without a fixed pattern. Gas molecules inside a container exhibit this kind of motion due to continuous collisions with one another and the container walls.

• A and B describe linear/translational motion.

• D describes periodic/orbital circular motion.

Correct Answer: D) relative density of a liquid

Explanation

(a)(1) Voluntary action - involves the response to a stimulus that is controlled at will by the brain. in this action, an impulse is carried from a sensory neurone via the spinal cord to the brain which interprets and sends the message back through the motor neurone to effector organ. The action is not automatic. e.g. running, writing, jumping, laughing, reading, smiling.

(II) Involuntary action or reflex action-It is a rapid or automatic response to a stimulus. It does not involve the brain for initiation. Therefore, the action is not under the control of the will, e.g. sneezing, coughing, knee jerk, salivation, secretion of grand, blinking

(b)(i) Functions of insulin: (1) Assists in oxidation of glucose to produce energy (2) regulates the amount or level of glucose in the blood (3) assists in protein synthesis in some cells

(ii) Functions of auxin.

(1) Promotes lateral bud development.

(2) promotes reproduction, flowering and fruit formation in plants.

(3) promotes the production of adventitious roots

(c) Experiment to show that plant roots respond positively to gravity:

Aim - To demonstrate that plant roots respond positively to gravity. Apparatus: A bean seedling, Wet blotting paper, damp saw dust, cupboard.

Procedure: Put some dust on a wet blotting paper and place the bean seedling on the saw dust horizontally. Carry the set up and place it inside a dark cupboard to eliminate light for few days.

Observation: When observed after few days, one will discover that the root has curved and growing downwards while the shoot grow upward. Conclusion: Since the root has grown downwards and the shoot upwards, we can say that roots respond to gravity, showing positive geotropism while the shoot shows negative geotropism.
