Correct Answer: C. 7.5m

Explanation

By similar triangles, \(\frac{8}{3}\) = \(\frac{8 + 12}{h}\)

\(\frac{8}{3} = \frac{20}{h}\)

h = \(\frac{3 \times 20}{8}\)

= 7.5m

Explanation

Features to be identified include:

(i) Continental shelf

(ii) Continental slope

(iii) Ocean deep

(iv) Continental edge Land

(v) Minor trench

(vi) Ocean ridge

(b)(i) Continental shelf: It has shallow, gentle slope with gradient of 1/500 and it is a continuation of the land to the sea. It occupies about 7% of the total area of the oceans. It is the richest fishing ground, allows ships to move inland and also allows recreational facilities e.g New found land

(ii) Continental slope: It is steep of depth up to 1801 5401 metres. It joins the continental shelf with the deep sea plain. It is located near the continent.

Correct Answer: D) antennae

Explanation

Prawns are a type of crustacean that have several body parts serving different functions. The question is asking which specific part of the prawn is used for sensory purposes. The options listed are carapace, mandible, tracheae, proboscis, and antennae. To answer the question correctly, we need to know what each of these body parts does. The carapace is the hard, protective covering over the prawn's body. It does not have any sensory function. The mandibles are the prawn's mouthparts that help it to crush and grind its food. The tracheae are the tubes that allow the prawn to breathe, and they do not have any sensory function. The proboscis is a long, flexible tube-like structure that some animals use to suck up their food. However, prawns do not have a proboscis. That leaves us with the antennae, which are the correct answer. Prawns have two pairs of antennae, and they are used for touch, taste, and smell. The antennae are sensitive to chemicals in the water, which allows the prawn to locate food and avoid danger. In summary, the correct answer to the question is option E: antennae. The antennae are the part of the prawn that is used specifically for sensory purposes, including touch, taste, and smell.

Correct Answer: A. be nursing a hidden a last agenda

Correct Answer: B. \(\gamma\)=3\(\alpha\)

Explanation

cubic and linear expansivity are related by this equation. γ=3α.

Explanation

(a)

(b)(i) 80th percentile = \(\frac{80 \times 60th}{100} = \text{48th mark}\).

= 31.5.

(ii) Median = \(\frac{60th}{2} = \text{30th mark} = 32.3\)

(iii) Upper quartile = \(\frac{3 \times 60th}{4} = \text{45th mark} = 35.1\)

Lower quartile = \(\frac{60th}{4} = \text{15th mark} = 29.7\)

Semi-interquartile range = \(\frac{35.1 - 29.7}{2} = 2.7\)
