Correct Answer: A. 2/11

Correct Answer: D. population increases much faster than food supply

Explanation

The Malthusian theory of population is best illustrated when population increases much faster than food supply. This is because the Malthusian theory argues that population growth is exponential, while food supply growth is linear. This means that the population will eventually outgrow the food supply, leading to famine, disease, and war

Correct Answer: C. secondary production

Correct Answer: D) Sweat

Explanation

Plants, like animals, produce waste materials that need to be eliminated from their systems. This process is known as excretion. The question asks which of the given options is not an excretory product of a plant. Option A states tannin, which is a bitter-tasting compound found in many plants. Tannins are excreted by plants to eliminate excess or unwanted materials. Option B states gum, which is a sticky substance that is excreted by certain plants to seal wounds or protect against predators. Option C states alkaloid, which is a group of nitrogenous compounds that are produced by plants as a defense mechanism against herbivores. Option D states sweat, which is the correct answer as it is not an excretory product of plants. Sweat is a fluid produced by human sweat glands and is used for thermoregulation. Plants do not have sweat glands and do not produce sweat. In summary, the correct answer to the question is Option D (Sweat), as it is not an excretory product of plants.

Explanation

The poem depicts a boy swinging to and fro on a swing. The emphasis is on the activity and it seems he is enjoying himself immensely as the swing moves " faster and faster".

More gets known about the boy as the poem progresses. Reference is made to his "blue shirt" billowing "in the breeze", and its comparison with "a tattered kite". What is here revealed is his background and his poverty which the words "blue" and "tattered" suggest.

As the boy's movement on the swing intensifies, more is suggested about the happenings on the swing. Now its rapid motion becomes disorienting as the boy loses bearing in the metaphor of "east becomes west". "north turns to south" and "the four cardinal points/ meet in his head". At this point, it is suggested, confusion sets in and.the boy is no longer at ease in his former state where he seems to be at home in familiar poverty and class.

The crisis of identity is then reached in the final stanza in the cry of "Mother!", in the one and only first line, to be followed by the series of rhetorical questions in the succeeding lines. These questions allude to the boy's origin and aspiration ending in the profundity of the line - "Why was my father jailed?" It seems that at this point the veil has been removed from the boy's face and, like a clairvoyant, he can see the unacceptable situation in which he and his race find themselves. The poignancy of the revelation is felt, rather than said, as a world of innocence crashes before the boy's eyes.

Correct Answer: C. arms and ammunition

Correct Answer: C. Crystallization would be efficient in separating out a salt whose solubility increases considerably with temperature

Explanation

Crystallization is based on the principles of solubility: compounds (solutes) tend to be more soluble in hot liquids (solvents) than they are in cold liquids. If a saturated hot solution is allowed to cool, the solute is no longer soluble in the solvent and forms crystals of pure compound.
