Correct Answer: D. silt and clay

Explanation

Both silt and clay particles have very small pores, which contribute to higher capillarity. When combined, the silt and clay would likely result in a soil with relatively high capillarity.

Correct Answer: C. astigmatism

Explanation

Astigmatism is a common refractive error of the eye that occurs when the cornea or lens has an irregular shape. In a normal eye, the cornea and lens have a smooth, evenly curved surface, similar to a sphere. However, in astigmatism, the cornea or lens may be more curved in one direction than the other, resulting in a refractive error.

Correct Answer: B. axial skeleton

Explanation

The skull is part of the axial skeleton. It is the bony structure that forms the head and encloses and protects the brain. The skull is located along the central axis of the body, and it is one of the key components of the axial skeleton.

Correct Answer: A. Colour of flower

Explanation

Colour of flower: The colour of flowers in plants typically shows discontinuous variation. Flowers can have specific colors like red, blue, yellow, or white, and individuals within a population will usually exhibit one of these distinct flower colors. There are no intermediate or blending colors between the different categories.

Correct Answer: B. holozoic

Explanation

Holozoic nutrition is a type of nutrition in which organisms consume solid organic materials. This is the type of nutrition seen in most animals, where food is ingested and then broken down through digestion. This is different from symbiotic (where two organisms live together and benefit from each other), saprophytic (where organisms feed on dead and decaying matter), and parasitic (where one organism benefits at the expense of another) nutrition.

Correct Answer: B. Eye, cerebellum and ear

Explanation

An individual was involved in a car accident and the illustrated structure was badly injured. Which of the following structures would most likely be affected?

Explanation

a.

b. -Carbohydrate;

-Protein;

-Lipids/fats and oil

-Vitamin.

c(i)-Takes in/receives food;

-Contains the teeth that chew/masticate the food;to increase the surface area of food particles;

-Contains salivary gland that secretes saliva that moistens the food;

-it also secretes the enzyme ptyalin which breaks down starch to maltose;

-Contains the tongue which tastes/rolls the food into bolus for swallowing.

c(ii). -Receives the food as chyme from the stomach;

-Receives pancreatic juice from pancreas

-Receives bile from the liver which reduces surface tension/emulsifies fats and oil;

-Contains amylase in pancreatic juice which hydrolyses starch to maltose;

-Contains trypsin which breaks down proteins to polypeptides;

-Contains lipase which breaks down fats and oil to carboxyl acid and glycerol;

-Provides large surface area for absorption of some digested food/vitamins and nutrients.

c(iii). -Temporarily stores food;

-Secretes dilute HCI/hydrochloric acid which destroys bacteria;

-Churns food;

-Contains enzymes which start the digestion of protein

d. Glucose and fructose are produced.

Correct Answer: B. mollusca

Explanation

The organism labelled IV is a Snail. Snails belong to the Phylum Mollusca. This phylum is characterized by soft-bodied animals that usually have an external shell, like snails, clams, and squids.

Correct Answer: D. pollination

Explanation

Pollination is not an activity associated with termites. Pollination is primarily carried out by various animals, such as bees, butterflies, birds, and bats, which transfer pollen from one flower to another, leading to fertilization and seed production. While some insects, like bees, are important pollinators, termites are not known for their role in pollination.

Correct Answer: C. adrenalin and kidney

Explanation

Adrenalin, also known as epinephrine, is not secreted by the kidney. It is secreted by the adrenal glands, specifically the adrenal medulla. The adrenal glands are small, triangular glands located on top of both kidneys. Therefore, the option 'Adrenalin and kidney' is incorrect
