GAMSAT GAMSAT Biological Sciences and Chemistry 2

Question 1

Which law states that the pressure of a gas is inversely proportional to its volume at constant temperature, relevant to GAMSAT chemistry?

Accepted Answer

Boyle's Law

Answer

Boyle's Law states that at constant temperature, pressure and volume of a gas are inversely proportional (P₁V₁ = P₂V₂).

Question 2

In GAMSAT biology, which phase of mitosis involves chromosomes aligning at the cell's equatorial plate?

Accepted Answer

Metaphase

Answer

During metaphase, chromosomes align along the metaphase plate (cell's equator), maximizing visibility under a microscope.

Question 3

A GAMSAT question asks about enzymes: which term describes the specific molecule an enzyme acts upon?

Accepted Answer

Substrate

Answer

The substrate is the specific molecule that binds to an enzyme's active site and undergoes a chemical reaction.

Question 4

Which type of reaction involves the gain of electrons, a concept commonly tested in GAMSAT redox chemistry?

Accepted Answer

Reduction

Answer

Reduction is the gain of electrons, remembered by the mnemonic OIL RIG (Oxidation Is Loss, Reduction Is Gain).

Question 5

In the context of GAMSAT genetics, which term describes alternate forms of a gene found at the same locus on homologous chromosomes?

Accepted Answer

Alleles

Answer

Alleles are different versions of the same gene occupying the same position (locus) on homologous chromosomes.
