Answer:
1. Are usually single-celled.
2. Do not contain membrane-bound organelles
3. Have DNA located in cytoplasm
Explanation:
Prokaryotic cells are single-celled organisms which have the following characters:
1. They lack a true nucleus and hence, they do not have their genetic material enclosed in a nuclear membrane-bound nucleus, rather it is present in the cytoplasm.
2. They lack all the membrane-bound organelles such as mitochondria, endoplasmic reticulum, etc.
3. They are usually. very small in size and hence are microscopic.
Examples include all the bacterias.
Nonrenewable sources deal with fossil fuels (coal, petroleum, etc) so renewable would be the sun, water, wind, things that can be replaced
Lithosphere (or geosphere) describes all the rocks, minerals and molten magma found on or in the Earth
The hydrosphere describes all the water on Earth – including liquid water (oceans, etc.) and vapour (precipitation)
The atmosphere describes the layer of gases surrounding the Earth and is divided into sections (stratosphere, etc.)
The biosphere is composed of all the living organisms on the planet (including plants, animals, bacteria, etc.)
The four spheres are interconnected, so human impact on one sphere will potentially effect other spheres
The release of plastic pollution into the oceans (hydrosphere) will impact on marine life (biosphere)
The production and release of CFCs into the atmosphere will effect the impact of UV radiation on the biosphere
