Explanation

Glucose is NOT an example of amorphous solids; it is a crystalline solid.

In contrast, glass, plastic, and rubber are amorphous solids.

It lacking a well-defined crystalline structure.

Explanation

Polysaccharides in plants are synthesized by the process of condensation.

During this process, monosaccharides are joined together through glycosidic bonds.

It releasing water molecules and forming complex carbohydrates like starch and cellulose.

Explanation

During light reactions, PS II receives electrons from the splitting of water.

This process, known as photolysis, generates oxygen, protons, and electrons.

It replenishing the electron supply in Photosystem II.

Explanation

A sarcomere is part of a myofibril between two Z lines.

It is the basic contractile unit of muscle fibers.

It responsible for muscle contraction through the sliding filament mechanism.

Explanation

Mesosomes are the invagination of bacterial cell structure cell membrane.

They are thought to play a role in cellular processes such as cell division and respiration in prokaryotic cells.

Explanation

The component of electronics that acts as a rectifier is a diode.

Diodes allow current to flow in one direction only.

It enabling the conversion of alternating current (A.C.) into direct current (D.C.) by blocking the reverse flow.

Explanation

The example of viruses having a polyhedral capsid with 252 capsomeres is adenovirus.

Adenoviruses are known for their icosahedral structure.

It containing exactly 252 protein subunits called capsomeres.

Explanation

The statement "It is selected by a breeder" is not true about natural selection.

Natural selection occurs in nature without human intervention.

Unlike artificial selection, where breeders select traits.

Explanation

Statement I, which indicates that taxes on all businesses have increased, is likely to lead to Statement II, where many small businesses will have to close their operations due to the higher tax burden.

Explanation

The centripetal acceleration of an object moving along a circle of radius 𝑟 with an angular speed 𝜔 is given by the formula 𝑎 = 𝑟 ⋅ 𝜔^2.

This formula indicates that the centripetal acceleration is directly proportional to the radius and the square of the angular speed.
