C Fossils allow scientists to have an idea of the time scale that traits evolved.
a polyphyletic genus of chlorophyte green algae in the family Volvocaceae.
Bacteria are single celled prokaryotic organisms. Prokaryotic means that they do not contain membrane-bound organelles. In simpler terms, they don't have cell parts within their cytoplasm. Bacteria are classified by their shape- round or cocci, rod or bacilli, and spiral or spirilla. Bacteria may also have long whip-like tails called flagella or be covered with small hair-like projections called cilia. Both structures are used for movement. Bacteria may have a cluster of free floating DNA in its cytoplasm called a nucleoid or they may have additional small rings of DNA called plasmids. Lastly, a bacterium have a cell wall made of a special compound called peptidoglycan which can provide an extra layer of protection from many environmental conditions.
Answer:
The diagram is depicting that light energy from the sun, carbon dioxide from air and water from soil are required for producing sugars and oxygen by the plant. The sugars produced by the process of photosynthesis is glucose. Oxygen is produced as by-product of this reaction. The glucose produced by the plant cells is utilized to carry out essential functions whereas the oxygen is mostly released into the air and it is also used for cellular respiration.
