Explanation

The molar mass of water (H₂O) is 18 grams per mole (H = 1g × 2, O = 16g).

So, 1 mole of water weighs 18 grams.

Explanation

• BCG (Bacille Calmette-Guerin) vaccine is primarily used to protect against Tuberculosis (TB).
• It is typically administered to infants and children in countries with high TB prevalence.

Explanation

 Lenz's law is a consequence of the law of conservation of energy. 

Lenz's law states that the induced current in a conductor always opposes the change in magnetic flux that caused it, which is essentially a way of ensuring that energy is conserved.

Explanation

Pyridine has a lone pair on nitrogen that is not involved in resonance, making it readily available for donation.

In aniline and phenol, lone pairs are delocalized into the aromatic ring, reducing basicity.

Explanation

Meiosis is a specialized type of cell division that produces gametes (sperm and egg cells).

It reduces the number of chromosomes in the daughter cells by half, ensuring that each gamete has only one copy of each chromosome.

This is crucial for sexual reproduction, as the fusion of two haploid gametes during fertilization restores the diploid chromosome number in the zygote. 

Explanation

The energy equivalent of 1 atomic mass unit (a.m.u) is given by Einstein's mass-energy equivalence formula E = mc².

1 a.m.u = 931 MeV/c², so the energy equivalent is 931 MeV.

Explanation

Photosynthesis is the process by which green plants use sunlight, carbon dioxide, and water to produce glucose (a chemical energy source) and oxygen.

It occurs mainly in the chloroplasts of plant cells, which contain chlorophyll.
