Answer:

C. The offspring are genetically distinct from the parents because they are produced by sexual reproduction.

Explanation:

Producing gametes like egg and sperm is a characteristic feature of organisms who reproduce sexually. Sexual reproduction is much more advantageous than asexual reproduction because in sexual reproduction variations are generated due to a phenomenon known as crossing over. Crossing over is the reason why progeny are not exact replica of their parents and have variations. Variations are very important because if all the members of a particular species are exactly the same then during sudden climate change they all may be wiped -off because they all being exactly the same have same tolerance power. But if members of a population have variations then some of them may have ability to withstand extreme climatic conditions and even if suddenly climate changes or a natural calamity occurs then at least some of the members of that species will survive and will be able to continue their generations.

Asbestos : substance known to cause lung cancer; found in older landfills

A renewable energy source implies energy that is feasible, that can't run out, or is unending, similar to the sun. It is additionally named 'alternative energy'. These assets are fit for recovery. The recovery of these sources includes a few biological cycles on a time scale. Sun, water, air, and heat from the earth are sustainable sources that we can use to make solar-based, tidal, wind, and geothermal energy. Renewable energy is additionally called green or eco energy.
