Interkinesis is brief intra meiotic interphase, which is found in some cases in order to synthesize deficient biochemicals. DNA synthesis does not occur in this phase of the cell cycle.

Hence, the correct option is (C).

Conditional differentiation (sometimes called temporal niche partitioning) occurs when species differ in their competitive abilities based on varying environmental conditions. For example, in the Sonoran Desert, some annual plants are more successful during wet years, while others are more successful during dry years.

Hence, the correct option is (A).

In Kranz anatomy, the bundle sheath cells have thick walls, no intercellular spaces and a large number of chloroplasts.

Kranz anatomy occurs in the chloroplast of C₄ plants such as sugarcane, maize (Zea mays), sorghum etc. It has two types of the photosynthetic cell arranged in a specific manner. These are bundle sheath cells that surround the vascular centres, and mesophyll cells that, in turn, surround the bundle sheath cells. Rubisco is localised only within internalised bundle sheath cells which helps in fixation of carbon dioxide. The bundle sheath cells have thick walls, no intercellular spaces and a large number of chloroplasts.

Hence, the correct option is (B).

As given, in the hydrogen atom jumps from the third orbit to the second orbit

From Archimedes' principle this apparent loss in weight is equal to the weight of the liquid displaced by the body.

rRNA is most abundant in the cell. It constitutes 80% of the total RNA of the cell. Ribosomes are composed of approximately 60% rRNA and 40% ribosomal proteins. rRNA is a type of non-coding RNA.

Hence, the correct option is (B).

Tendons connect the bone to muscle.

A tendon is a fibrous connective tissue which attaches bone to muscle. Tendons may also attach muscles to structures such as the eyeball. A tendon serves to move the bone or structure. A ligament is a fibrous connective tissue which attaches bone to bone, and usually serves to hold structures together and keep them stable.

Hence, the correct option is (D).

Very simple, as +I groups are attached to a carboxylic acid, the acidic nature decreases. As the size of +I groups increases, the acidity decreases proportionally. Whereas the -I groups enhance the acidity. As in alcohols, the acidity is dependent on the same factors in the same way but compared to carboxylic acids, alcohols are less acidic due to their weak alkoxide ion (RO-). As the aromatic groups are connected, the acidic nature is enhanced due to resonance. So an aromatic carboxylic acid is more acidic than its aliphatic counterpart.

The order of acidity therefore is,

4 > 3 > 1 > 5 > 2

Hence, the correct option is (C).
