Answer:
B. plasma membrane
Explanation:
Both plants and animals are eukaryotic organisms, it means that their cells contain 1-a nucleus that has linear chromosomes and 2-membrane-bound organelles such as mitochondria and endoplasmic reticulum. Moreover, chloroplasts are organelles found in the cells of plants and algae. On the other hand, bacteria are prokaryotic unicellular organisms that have neither an envelope-enclosed nucleus nor other specialized organelles. Most bacteria contain a genome composed of a single DNA molecule (i.e., one circular chromosome).
The answer is estuary. An estuary is a mostly encased seaside assemblage of bitter water with at least one waterways or streams streaming into it, and with a free association with the vast ocean. Estuaries shape a move zone between stream conditions and oceanic situations.
For photosynthesis to occur, plants need sunlight, water, carbon dioxide and chlorophyll. Through the process of photosynthesis plants convert light energy into chemical energy. They use this energy to make food which they store as sugars.
The correct answer is: reduce the loss of body heat to the environment. A <span>countercurrent heat exchanger works by transferring heat from one part of the body to another that has cooled down. For example, in dolphins, body parts of a high surface area such as flippers are rich in veins. Blood running through these veins that is cooled down is run close to arteries containing warmed-up blood, and some of the heat energy from the arteries is transferred to the veins, thereby allowing the dolphin to conserve heat energy. </span>
