Carbon shares 4 electrons to complete its valence shell
Answer:
No, since DNA does code for certain traits, others are introduced or changed by the environment. For example, some adaptations are not coded in DNA, such as dying hair. According to the gene, hair is to be black, for example, but it can be changed to look pink. Another example is when a person is first born. When they are, some bacteria enter the system of the baby --- mostly good. Then the baby's gut will be different, and the bacteria in the gut are not coded by the DNA. So, living things are not only the product of DNA, as there are extraneous factors that affect living things as well.

Answer:
phytoplankton
Explanation:
Phytoplankton can be defined as a set of photosynthesizing microorganisms that live floating on the water surface. It is composed of microscopic algae and cyanobacteria, which can be unicellular, colonial or filamentous. These microorganisms are defined as the primary producers of an ocean grazing food network.
Because phytoplankton live in aquatic environments - both in limic (eg lakes) and marine environments - they have a number of adaptations that guarantee their survival in the water column. Some of these microorganisms, for example, have flagella that aid locomotion; others, in turn, have gas vacuoles that aid in flotation, while some of them have mucilage, which surrounds the cells and ensures protection, flotation and locomotion.
