Explanation

Carnivores have very large canine teeth for tearing flesh.

In herbivores, canines are reduced or absent.

Omnivores have moderate-sized canines.

Explanation

Lack of insulin causes diabetes.

Diabetes is a condition that happens when your blood sugar (glucose) is too high.

It develops when your pancreas doesn't make enough insulin.

Explanation

The term fluids refers to both liquids and gases, as they can flow.

Liquids specifically are also classified under fluids because of their ability to take the shape of a container.

Explanation

A red object reflects only red light.

A blue glass absorbs red light, so no light passes through → the object looks black.

Explanation

Displacement is the change in position of a body in a specific direction (a vector quantity).

Distance is the total path covered without considering direction.

Explanation

A liquid boils at its boiling point, where its vapor pressure equals the external atmospheric pressure.

Melting point is for solid → liquid change, not boiling.

Explanation

In a neutral atom, the number of protons = electrons, ensuring electrical neutrality.

Protons are not always equal to neutrons or nucleons (protons + neutrons).

Explanation

Boyle’s Law: At constant temperature, pressure is directly proportional to density (P ∝ ρ).

This is because P ∝ 1/V, and since ρ = m/V, higher pressure means higher density for a fixed mass.

Explanation

The SI unit of impedance is the ohm (Ω).

Impedance, like resistance, is measured in ohms.

It can be represented as a complex number.
