Explanation

(a) Location:Tropical grasslands are located in the tropics while temperate grasslands are located in temperate latitude. Again tropical grasslands are found between 10° and 30° North and South while temperate grassland are found between 30° and 40° North and South of the Equator

(b) Climate:Tropical grassland has moderate rainfall (25-150cm) while temperate grassland has lower rainfall (40-50cm) Tropical grassland is not all the year round but temperate grassland has cold winter and warm summers. In tropical grassland, summer temperature is 32°C and 21°C while temperate grassland has 18°C in summer and —19°C in winter.

(c) Characteristics:Tropical grassland contains scattered trees while temperate grassland is almost treeless. Trees in the tropical grassland are bigger than those of temperate-grassland.jropical grasses are tough while temperate grasses are succulent. Example of tropical grass is elephant grass while temperate grass is willow.

Correct Answer: A. Interpretation of law

Correct Answer: B. \(\frac{2}{5}\)

Explanation

\(A = {3, \sqrt{2}, 2\sqrt{3}, \sqrt{9}, \sqrt{7}}\)

n(A) = 5

Let the rational nos = R

n(R) = 2 (3, \(\sqrt{9}\))

P(R) = 2/5

Correct Answer: D. Ismail (A.S).

Correct Answer: C. stable in value

Correct Answer: B) improvement of the variety of crops

Explanation

Artificial pollination is a technique used in plant breeding to cross two different plants with desirable traits to produce offspring with even better traits. This technique involves manually transferring pollen from the male reproductive organ of one plant to the female reproductive organ of another. The question is asking about the effect of using artificial pollination in plant breeding. From the options given, the correct answer is option B which states that artificial pollination improves the variety of crops. This is because it allows breeders to control which plants are used in the breeding process, resulting in offspring with desirable traits such as increased yield, disease resistance, or better taste. Option A, production of healthy crops, is not necessarily the direct effect of artificial pollination, although it could be a secondary effect. Option C, lengthening the maturity time, is not a desirable effect in plant breeding as it would mean that the crops would take longer to mature, resulting in a longer time to harvest. Option D, making crops susceptible to diseases, is also not a desirable effect as it would mean that the crops would be more vulnerable to diseases, resulting in lower yields. In conclusion, the effect of using artificial pollination in plant breeding is the improvement of the variety of crops. This technique allows breeders to control the traits of the offspring, resulting in plants with desirable traits such as increased yield, disease resistance, or better taste.

Correct Answer: B. Clans

Explanation

The Ijaw people of pre-colonial Nigeria were organized into clans. A clan is a group of people united by actual or perceived kinship and descent. In the case of the Ijaw people, these clans were often made up of several villages and communities that shared common ancestry.
