Explanation

Let A and B denote the events that the man wins contracts X and Y respectively.

Then P(A) = 0.5

P(A') = 1 - 0.5 = 0.5

P(B') = 0.3

P(B) = 1 - 0.3 = 0.7

(a) The probability that the man wins both contracts = \(0.5 \times 0.7 = 0.35\).

(b) The probability that the man wins exactly one of the contracts is \(P(A) \times P(B') + P(B) \times P(A')\)

= \(0.5 \times 0.3 + 0.7 \times 0.5\)

= \(0.15 + 0.35\)

= \(0.50\)

(c) Neither of the contracts (i.e not X, not Y) = \(P(A') \times P(B')\)

= \(0.5 \times 0.3\)

= \(0.15\)

Explanation

(a) Highlight Peter's advice to Christians living among non-Christians: 1 Peter 2:9— 25:

(i) Peter advised that Christians should abstain from the passion of the flesh .

(ii) Maintain good conduct among the Gentiles.

(v) By doing right, they would silence the ignorance of foolish-men.

(vi) They should live as free men but do not use their freedom as pretext for evil.

(vii) They should live as servants of God.

(viii) Honour all men

(ix) Love the brotherhood

(x) Fear God.

(xi) Honour the Emperor.

(b) Three ways to promote good relationship:

(i) Participation in community development projects with non Christians.

(ii) Contribution towards the needs of non-Christians.

(iii) Participation in social activities with non-Christians.

(iv)Accommodation of programmes and activities of non-Christians.

(v) Acceptance of non-Christians in Christian institution e.g. schools.

(vi) Attendance at programmes of non-Christians.

(vii) Educative interaction about other religions.

(viii) Religious tolerance.

Correct Answer: C) microchondrion

Explanation

The question is asking about where oxidative phosphorylation occurs in aerobic respiration. Aerobic respiration is a process by which cells convert glucose and oxygen into energy, carbon dioxide, and water. Oxidative phosphorylation is the final step of aerobic respiration, where the most ATP (adenosine triphosphate) is produced. ATP is the molecule that provides energy for cellular activities. Option A suggests that oxidative phosphorylation occurs in the cytoplasm, which is incorrect. Cytoplasm is where glycolysis takes place, the first step in aerobic respiration. Option B suggests that lysosomes are involved in oxidative phosphorylation, which is also incorrect. Lysosomes are involved in the breakdown of cellular waste. Option D suggests ribosomes are involved in oxidative phosphorylation, which is incorrect. Ribosomes are involved in protein synthesis. Option C is correct. Oxidative phosphorylation takes place in the mitochondria. Mitochondria are organelles that are involved in cellular respiration, which includes aerobic respiration. Within the mitochondria, there are two membrane systems: the outer mitochondrial membrane and the inner mitochondrial membrane. The inner membrane is where oxidative phosphorylation occurs. In summary, the correct answer to this question is Option C: mitochondrion. Oxidative phosphorylation, the final step of aerobic respiration, takes place in the inner mitochondrial membrane.

Correct Answer: A. \(11.6cm^2\)

Explanation

\(\theta = 115° , radius = 3.4cm^2\)

Area of a sector = \(\frac{\theta}{360} \times \pi r^2\)

= \(\frac{115}{360} \times \frac{22}{7} \times 3.4\times 3.4\)

= \(\frac{29246.4}{2520}\)

= \(11.6cm^2\)

Correct Answer: A. a gradual increase in the average kinetic energy of the particles

Correct Answer: A. Ezra
