Answer:
A, B, E
Explanation:
The guard cells block water loss (transpiration) when the cells are turgid. To become flaccid, the cells must lose water. This is accomplished when the surrounding cells accumulate K+ making them hypertonic compared to the guard cells. The guard cells then lose water via osmosis.
Answer:
New cells are spontaneously created from existing cells
Explanation:
In the 1830's, three scientists namely: Matthias Schleiden (a botanist), Theodor Schwann (a zoologist) and Rudolf Virchow proposed the Unified cell theory. In this theory, three parts were universally accepted and they are as follows:
1) Cells are the fundamental and basic unit of all life and structure.
2) All living organisms are made up of one or more of these cells.
3) New cells arise from already pre-existing cells.
These three parts are the widely accepted parts of the cell theory. Although, it was once believed that new cells arose from inorganic matter. This theory, called spontaneous generation or abiogenesis was later disapproved.
Therefore, the statement that, "new cells are spontaneously created from existing cells" is not a part of the CELL THEORY.
The answer is-Hydroelectric Hope this help
<span>An example of an epithelial tissue where gases are exchanged is alveolar epithelium, which can be found in the lungs. This tissue is simple epithelial tissue. This is to be expected because the cell layer needs to be thin enough for the gasses like carbon dioxide and oxygen to diffuse or pass through. Stratified epithelial tissue contains several cell layers that would impair the exchange of gasses.</span>
you got this i believe in you
