Different amounts of light pass-through matter when it moves through it in different ways. Almost all of the light shining on transparent things can pass through them. Transparent items include glass, air, and clear plastic.
Burning plastics endangers flora, human and animal health, and emits hazardous chemicals into the environment, including dioxins, furans, mercury, and polychlorinated biphenyls (BCPs). Burning plastic releases extremely dangerous pollutants that greatly raise the risk of cancer, respiratory diseases, and birth problems. Additionally, it might seriously harm the hormonal system and internal organs. If the stench is bad, it could stay there for a few days. It might, however, improve a few hours later.

There are many atoms of Hydrogen in the water on the planet. Do you think those atoms will still be in
existence a million years from now?
Answer:
The hydrogen atoms in the water on the planet will still be in existence a million years from now because the water we are drinking is already more than a billion years old. Also, the water cycle will continue to produce water through its cycle to make us rain water. The rain water will then be purified for other uses like personal cleaning and washing our everyday things/resources/materials.

3) Why should we store seed in moisture proof polythene bags
The orthodox seeds can be put in sealed moisture-proof containers after being dried to the proper moisture content. This avoids the need for prolonged dehumidification.
When refrigeration is used to maintain controlled low temperatures and moisture-proof containers, long-term storage is most successful. When refrigeration is used to maintain controlled low temperatures and moisture-proof containers, long-term storage is most successful. Generally speaking, storage life shortens as seed moisture content rises. Low moisture level—below 4%—can also harm seeds due to excessive desiccation or result in hard seededness in some crops. If seeds are kept at high moisture content, losses could be very quick due to mould growth. The seed will mold as a result of the retained moisture, ruining the sample. Keep them cold and dry to increase their shelf life. Seeds quickly absorb moisture again. Keep seeds in airtight containers like tin cans or glass jars with tight fitting lids to maintain dryness. Include a substance that absorbs moisture.Learn more about Seeds here :

What are cells?Cells are defined as the basic unit of life.
All forms of life are composed or exists as singe cells.
Some organisms are composed of many cells while some organisms are only singe cells.
Organisms that are composed of many cells are called multicellular organisms whereas organisms that are composed of just one cell, are called unicellular organisms
All the cells of a unicellular organism such as humans contains the same DNA of that individual. However, the genes in the DNA of cells are expressed differently according to the specialization of the cell.
