Chlorofluorocarbons (CFCs) are the primary substances responsible for the depletion of the ozone layer.

Single-use plastics, such as bags and bottles, are a major contributor to plastic pollution in oceans.

Glucose is the main substrate for respiration in plants, as it is broken down to release energy.

Malaria is primarily transmitted by the female Anopheles mosquito.

Malaria is primarily transmitted through the bite of infected female Anopheles mosquitoes.

The reaction of 1-bromobutane with sodium hydroxide in ethanol leads to elimination, forming butene as the major product.

The male gamete in flowering plants is called pollen, which is produced in the anthers of the stamen.

The male reproductive part of a flower is called the stamen, which consists of the anther and filament. The anther is the part that produces pollen.

The mass defect is the difference between the mass of the nucleus and the sum of the masses of its individual nucleons, which accounts for the binding energy.

The maximum displacement from the mean position in simple harmonic motion is called the amplitude.

The d subshell can hold a maximum of 10 electrons.

The p subshell can hold a maximum of 6 electrons.

The maximum number of electrons in an energy level is given by the formula 2n². For n=3, it is 2(3)² = 18.

The maximum number of electrons in an energy level is given by 2n^2. For n=4, it is 2(4^2) = 32.

For the first order of bright fringe in reflected light, the minimum thickness of the soap bubble is λ/4 due to the phase change upon reflection.

Molality (m) = moles of solute / kg of solvent = 3 moles / 1 kg = 3 m.

Molality (m) = moles of solute / kg of solvent = 3 moles / 0.5 kg = 6 m.

Cyclohexane is a cyclic alkane with the formula C6H12.

Ethyne, also known as acetylene, has the molecular formula C2H2.

The simplest alkyne is ethyne (acetylene) with the molecular formula C2H2.

Nucleotides are the monomers that make up nucleic acids.

When the object is placed between the focal point and the mirror, the image formed is virtual and erect.

When the object is placed beyond 2F, the image formed by a convex lens is real, inverted, and diminished.

The net gain of ATP from one molecule of glucose during aerobic respiration is approximately 30-32 ATP, depending on the efficiency of the process.

The net gain of ATP molecules from one molecule of glucose during aerobic respiration is approximately 30-32 ATP.

The normal pH range of human blood is tightly regulated between 7.35 and 7.45, which is essential for proper physiological function.

The normal pH range of human urine is typically between 6.0 and 7.0, indicating it is slightly acidic.

The normal respiratory rate for a healthy adult at rest is typically between 12 to 20 breaths per minute.

Osmotic pressure (π) = iCRT = 2 * 0.5 * 0.0821 * 298 = 24.5 atm. Therefore, π = 6.15 atm.

Osmotic pressure (π) = nRT/V = (0.1 mol)(0.0821 L·atm/(K·mol))(298 K) = 2.03 atm.
