Explanation

Creeping animals (such as snakes, lizards, and turtles) are typically classified under the class Reptiles.

Reptiles are cold-blooded and move by creeping or slithering on land.

Explanation

The breakdown of proteins results in the production of ammonia, which is then converted into urea in the liver.

Urea is excreted from the body through the kidneys in the urine.

Explanation

6CO₂ + 6H₂O → C₆H₁₂O₆ + 7O₂

The given reaction is the photosynthesis equation, where carbon dioxide and water form glucose and oxygen.

To balance oxygen atoms, the reaction requires 6 oxygen molecules (O₂), which contain 12 oxygen atoms on both sides.

Explanation

The calyx is the outermost whorl of a flower, consisting of sepals, which are usually green and leaf-like.

It protects the inner parts of the flower, especially in the bud stage, before blooming.

Explanation

When the thoracic cavity expands, lung pressure decreases, causing air to flow in (inhalation).

This follows Boyle’s Law, where increased volume leads to decreased pressure.

Explanation

Sphingomonas is a genus of bacteria being studied for its ability to biodegrade polythene and other plastics efficiently.

Scientists are exploring its potential to shorten plastic degradation from hundreds of years to just a few months.

Explanation

Passive immunity is provided to the fetus when maternal antibodies (especially IgG) cross the placenta.

This protection is temporary.

It helps the baby fight infections until its own immune system develops.

Explanation

Electrons involved in bond formation are in the valence shell, the outermost electron shell.

These electrons participate in chemical bonding between atoms.

Explanation

Explanation

Cobalt chloride paper is used to detect moisture; it turns from blue to pink in the presence of water vapor.

This change helps demonstrate transpiration as water evaporates from the leaf surface.
