The roots are z = ±i.

The roots of the polynomial can be found by factoring it as (x-2)(x-3) = 0, giving roots 2 and 3.

A number is divisible by 11 if the difference between the sum of the digits in odd positions and the sum of the digits in even positions is 0 or a multiple of 11.

Hexanoic acid is a saturated carboxylic acid.

Stearic acid is a saturated fatty acid, meaning it has no double bonds between carbon atoms.

Cyclohexane is a saturated hydrocarbon, containing only single bonds.

Temperature is a scalar quantity as it has magnitude but no direction.

2-pentanol has the hydroxyl group on the second carbon, making it a secondary alcohol.

2-Pentanol has the hydroxyl group attached to a secondary carbon, making it a secondary alcohol.

Dimethylamine is a secondary amine as it has two alkyl groups attached to the nitrogen.

Excessive caffeine can lead to insomnia and disrupt sleep patterns.

Potassium deficiency often results in leaf curling and marginal leaf scorch, indicating poor water regulation.

Genetic modification of crops is a significant application of biotechnology in agriculture, allowing for enhanced traits such as pest resistance and increased yield.

Overregulation and bureaucratic hurdles pose significant challenges for NGOs in India, affecting their operational efficiency.

Deforestation leads to soil erosion as the protective cover of trees is removed, making the soil more susceptible to being washed away by rain.

A singular matrix is one that does not have an inverse, which occurs when its determinant is zero. The matrix [[2, 3], [4, 6]] is singular.

To solve for x, add 9 to both sides and then divide by 3: 3x = 9, thus x = 3.

Solving the inequality gives 3x < 9, thus x < 3.

Both mutation and gene flow contribute to genetic variation in a population, providing the raw material for evolution.

All of the options listed (mutation, gene flow, and sexual reproduction) are sources of genetic variation in populations.

A square matrix is one where the number of rows is equal to the number of columns. Among the options, only 3x3 has equal rows and columns.

Enthalpy is a state function, while work and heat are not state functions as they depend on the path taken.

Glycogen is the storage form of glucose in animals, while starch serves this role in plants.

The -CH3 group is a strong +I effect group as it donates electron density through the inductive effect.

-NO2 is a strong -M group as it withdraws electron density through resonance.

HCl (hydrochloric acid) is a strong acid that completely dissociates in water.
