Answer:
D. Because it contains membrane-bound organelles
Explanation:
One of the defining features that separates eukaryotic cells from prokaryotic cells would be the organelles, specifically they are membrane-bound. Although prokaryotes also hve organelles, they are not enclosed. This is why they say that eukaryotes have a TRUE NUCLEUS because it is well defined by the membrane that encloses it.
Prokayotic cell organelles are kind of like floating around within its cytoplasm.
Answer:
This is because cell walls protect the cells and allow plants to grow to great heights.
Explanation:
Cells walls are made of a cellulose are only found in plant cells.
Quadrat method is used for estimating the number of individuals in an area. In this method, a large square area on the ground or water surface is marked, call it an enclave. The number of animals present in this enclave is counted. Then by assuming that the animals are less migratory and are uniformly distributed, their number for a large area is estimated by the use of unitary method of calculation. Example a 4 square feet area has 2 snails, then a 1000 square feet area will have (1000 x 2)/4, i.e, 500 snails in it. Fishes can be counted using this method only if they are confined in a small water body like a lake or a pond. Rivers are flowing so the fishes may move along its length which can give us an underestimate or an overestimate of their numbers. Sea has its depth and huge area, and fishes can be moving randomly in it. Hence this method will not work for river and sea fishes.
<span>Cell membrane plays an important role in maintaining the homeostasis by controlling the substances that penetrate the cell, either entering the cell, or leaving the cell. Since the cell membrane is a phospholipid bilayer, it can control the transition of water and ions.</span>
Answer:
Answer is C.
Explanation:
Electrophoresis describes the movement of particles in a gel, influenced by an electric charge.
It is use to separate DNA particles based on their charge and size. Some of its types are native or buffer gels, gradient gels among others.
