- <em>the plant body is un</em><em>i</em><em>cellular </em><em>and</em><em> </em><em>biflagellate</em><em>.</em><em> </em>
- <em>the cell is </em><em>spheric</em><em>a</em><em>l</em><em> </em><em>or cylindrical in shape</em><em> </em><em>.</em>
- <em>the Protoplasm of the cell is always surrounded by a thin </em><em>cellulose</em><em> wall</em><em> </em><em>.</em>
- <em>a pair of </em><em>flagella</em><em> </em><em>of</em><em> </em><em>equal</em><em> </em><em>size</em><em> </em><em> </em><em>is present at the anterior </em><em>end</em><em>.</em><em> </em><em>it moves by the lashing actions of the </em><em>flagella</em><em>.</em><em> </em>

Pork and beef insulins are similar to human insulin, differing only in one or a few amino acids. However, even a slight difference is enough to elicit an allergic response in some people. To overcome this problem, researchers looked for ways to make insulin that would more closely resemble human insulin.
Answer and explanation;
Nucleus; houses a cell's DNA and its processes include protein, replication and packaging for cell division. It is also the site for transcription.
Cytosol; coordinates a responsible to the environment, metabolism and motor proteins.
Endomembrane system; includes the nuclear envelope (surrounds nucleus), rough and smooth ER, golgi body, lysosomes?vacuoles, peroxisome and plasma membrane.
Semiautonomous organelles; mitochondria (animals) and chloroplast (plants) which provide energy for the cell.
Answer:
Plasmolysis
Explanation:
In the image 1 the cell is having sufficient quantity of water leading to a turgid cell.
The image 1 plant cell is in a dilute solution in which water enters into cell from external medium.
The image 2 plant cell is exposed to a solution which is high concentrated solution.
Due to this high concentrated solution the water present in the cell is send out by exosmosis.
Due to loss of water from plant cells the protoplasm in plant cell shrinks in which cell membrane gets separated from cell wall.
This shrinkage of protoplasm by loss of water is called plasmolysis.
The similarities between bones of humans and other animals shows that every living creature on earth has a common ancestor, even if that common ancestor is as simple as a sing-celled organism.
