Explanation

• Decreased industrial activity can lead to a reduction in pollution levels.
• As fewer pollutants are released into the environment.

Explanation

• Osmosis is the process where a solvent, typically water.
• It moves through a porous membrane from an area of lower solute concentration to an area of higher solute concentration.

Explanation

• Distillation is a process that removes dissolved physical and chemical impurities from water.
• By boiling the water and then collecting the condensed steam, which is free from many impurities.

Explanation

• Chlorination is the process of adding disinfectants, such as chlorine, to water to kill harmful microorganisms.
• It prevent the spread of waterborne diseases.

Explanation

• Filtration is a process that removes suspended sand particles and insoluble physical impurities from water.
• By passing it through a filter medium, such as sand, gravel, or a membrane.

Explanation

• An ecosystem includes all the living components (biotic factors) like plants, animals, and microorganisms, and non-living components (abiotic factors).
• Like soil, water, air, and sunlight, interacting with each other.

Explanation

• Sperms fuse with eggs to form a zygote, which is the single cell that results from fertilization.
• The zygote then develops into an embryo, and later a fetus, as it grows and matures.

Explanation

• Fertilization is the process where a male gamete (pollen) fuses with a female gamete (ovule) to form a zygote.
• It develops into a seed and eventually a new plant.

Explanation

• Roots, stems, and leaves of plants can produce offspring through asexual reproduction.
• It involves the growth of new individuals from vegetative parts of the parent plant.

This can occur through:

• Roots: adventitious roots, root cuttings
• Stems: stem cuttings, runners
• Leaves: leaf cuttings, leaf propagation

Explanation

• Asexual reproduction is a type of reproduction where only one parent is involved, and offspring are produced without the fusion of gametes (sex cells).
• This means that the offspring are genetically identical to the parent.
