Answer:
1). Renewable energy resources include: solar, wind, water (hydro), biomass, and
2). Nonrenewable energy resources include: coal, nuclear, oil, and natural gas.
Explanation:
Renewable energy resources are replenished naturally and over relatively short periods of time while Nonrenewable energy resources as their name applies are limited in their quantity and supplies too.
These forms of energy are primary formed when fossil fuels are destroyed by use, i.e they are not been recovered(nonrenewables); which brings in alternative sources(renewables).
Human supplies of fossil fuels and minerals are dwindled fast. These are nonrenewable resources as we cannot produce them by any process. Our demand for these limited resources, however, is constantly increasing. So we to cut down their wastages, find acceptable alternatives and also recycle them where possible.
Both mitochondria and ribosome are so tiny structure, it can not be seen under light microscope. It needs more magnification to study the detail structure, hence electron microscope is best to use.
<h3>What is ribosome ?</h3>
Ribosomes are small membrane less organelles and are the sites of protein synthesis.
It is present in are found in both eukaryotic and prokaryotic cells.
Ribosomes can either be present alone or in groups in cytoplasm while some ribosomes are attached to the endoplasmic reticulum called as rough endoplasmic reticulum.
These are composed of ribosomal protein and RNA, have two subunit larger and smaller subunit.
