Explanation

Bioremediation is the use of living organisms like bacteria and plants to remove or neutralize pollutants from the environment.

It is an eco-friendly method to clean up contaminated soil, water, or air.

Deductive reasoning: General to specific.

Inductive reasoning: Specific to general.

Explanation

Silicon has the highest melting point among the given elements due to its giant covalent structure.

It requires more energy to break the strong covalent bonds.

Explanation

The pressure of oxygen in the lungs is 104 torr. 

The partial pressure of oxygen in the lungs, also known as the alveolar partial pressure of oxygen (PaO2),

It is the pressure exerted by oxygen within the alveoli.

At sea level, atmospheric pressure is 760 mmHg.

Since oxygen makes up approximately 21% of air,

The partial pressure of oxygen in atmospheric air is 0.21 x 760 mmHg = 159.6 torr

However, as air enters the alveoli, it mixes with water vapor and carbon dioxide, which slightly reduces the oxygen partial pressure.

Therefore, the actual partial pressure of oxygen in the alveoli is around 104 torr. 

Explanation

 Human tissues, particularly in organs like the brain and kidneys, can contain approximately 85% water.

The exact percentage varies by tissue type, but many, especially soft tissues, are largely composed of water.

Explanation

Meiosis reduces the chromosome number by half, forming haploid cells (e.g., gametes).

This ensures that during fertilization, the diploid number is restored in the offspring.

Explanation

The frog eats the caterpillar (a primary consumer), making the frog a secondary consumer.

It occupies the third trophic level in the food chain: Producer → Primary → Secondary → Tertiary.

Explanation

Carbohydrates are the body’s primary and quickest source of energy, especially glucose.

They are broken down during cellular respiration to release ATP (energy).

Explanation

Blood group A can have genotypes IAIA (homozygous) or IAi (heterozygous).

Since IAIA is one valid genotype for blood group A.

Explanation

Trypsin works best in a basic (alkaline) environment like the small intestine.

The stomach is highly acidic, which inhibits trypsin’s activity.
