Explanation

2 is the smallest and the only even prime number.

A prime number has exactly two distinct factors: 1 and itself; 1 does not meet this condition.

Explanation

Lipid-rich components of bacterial cells present in the bacterial membrane.

Bacterial membranes present a large diversity of amphiphilic lipids.

Explanation

Ammonia (NH₃) has a trigonal pyramidal shape due to one lone pair on the nitrogen atom.

The molecular geometry results from sp³ hybridization and lone pair-bond pair repulsion.

Explanation

Explanation

"Percent" means per hundred, so 1% = 1 ÷ 100

It can also be written as a decimal: 0.01.

Explanation

Explanation

Gravitational force (F) is given by:

F ∝ (m1 * m2) / r²

If both masses (m1 and m2) are halved:

New force F' ∝ ((m1/2) * (m2/2)) / r²

F' ∝ (m1 * m2) / (4 * r²)

F' = F / 4

The gravitational force becomes one fourth.

Explanation

Temperature increases kinetic energy, speeding up diffusion.

Intermolecular forces affect how easily gas particles move past each other.

Molecular mass affects rate inversely — lighter gases diffuse faster (Graham's Law).

Explanation

"Say to us" changes to "tell us", and present tense remains as it's a universal statement.

"You" changes to we, and "our" to their to match the speaker and listener perspective.
