The answer to your question is B.Chromatin
Electric cars and the renewable energy that create the electricity to charge
them protects environmental quality.
Renewable energy arise from renewable sources such as sunlight, wind etc
and they are always replenished from time to time. This form of energy
doesn't emit compounds such as greenhouse gases thus helping to protect
environmental quality.
Non renewable energy is mostly gotten from fossil fuels which emits carbon
and other compounds . These compounds pollute and reduces
environmental quality.

The three types of point mutations that can occur during replication/protein synthesis such as Insertion, Deletion, and Frameshift.
Answer:
D
Explanation:
Methanogens are prokaryotes and therefore have prokaryotic cells. They are single-celled archaea. They are found in hypoxic conditions like the first stomach of ruminants where they digest molecules like cellulose and produce methane as a byproduct. The rest are composed of eukaryotic cells which are much larger than prokaryotic cells and their organelles are membrane-bound (unlike prokaryotes).
Answer:
- <u>Eukaryotes</u> are organisms that contain more than one cell with membrane-bound organelles and a nucleus.
- Organisms that contain only one cell and do not contain a nucleus or membrane-bound organelles are known as <u>prokaryotes</u>.
Explanation:
According to their structural and functional complexity, organisms can be classified into eukaryotes and prokaryotes.
- <em><u>Eukaryotic organisms</u></em><em> are formed by cells that have a true nucleus -where DNA is located- and specialized structures called organelles, with a system of endomembranes that compartmentalize the intracellular space. These organisms are usually pluricellular, given the ability of eukaryotic cells to group together to form tissues.
</em>
- <em><u>Prokaryotic organisms</u></em><em> are single cells, lacking a nucleus - genetic material is scattered in the cytoplasm - and do not possess organelles. The prokaryotic cells that form these organisms are incapable of binding together, so they do not form tissues.</em>
Some unicellular organisms are prokaryotic cells, like some parasitic microorganisms, such as amoebas.
