Explanation:
1)The cell membrane functions as a semi-permeable barrier, allowing a very few molecules across it while fencing the majority of organically produced chemicals inside the cell. Electron microscopic examinations of cell membranes have led to the development of the lipid bilayer model (also referred to as the fluid-mosaic model). The most common molecule in the model is the phospholipid, which has a polar (hydrophilic) head and two nonpolar (hydrophobic) tails.
2) simple diffusion across the cell plasma membrane. The structure of the lipid bilayer allows small, uncharged substances such as oxygen and carbon dioxide, and hydrophobic molecules such as lipids, to pass through the cell membrane, down the concentration gradient is , by simple diffusion.
3) some molecules, such as carbon dioxide and oxygen, can diffuse across the plasma membrane directly, but others need help to cross its hydrophobic or however, because they are charged the polar, they can't cross the phospholipid part of the membrane without help .
4) during fission a copy of the DNA is made and attached to the cell membrane as well. As this cell elongate in preparation for fission, the two DNA copies are pulled apart two opposite ends of the cell. New membrane material is deposited between the two ends of the cell, and a new wall grows between them .

6) example of passive transport and active transport across a cell membrane so, cell membranes are semipermeable meaning they have control over what molecules can or cannot pass through. Some molecules can just drift Inn.
Vegetation controls water and nutrient loss from ecological lesson can we learn from the controlled experiment on the clearing of forests.
<h3>
What about clearing of forest?</h3>
- Deforestation is the intentional clearing of wooded land.
- Forests have been cleared throughout history and into the present era to make room for agriculture and animal grazing as well as to obtain wood for fuel, manufacture, and construction.
- Deforestation has dramatically altered the landscape all around the planet.
- The process of permanently removing vegetation, such as trees and bushes, together with their roots, is known as clearing woods and forests.
- There are both direct and indirect causes of deforestation.
- Natural factors including storms, fires, parasites, and floods are among the direct culprits.
- Human activities include the extension of agriculture, the raising of livestock, the extraction of timber, oil, and minerals, the building of dams, and the development of infrastructure.

Answer:
I think the difference between Charophyta and Chlorophyta is that Charophyta forms a paraphyletic group.
Explanation:
<span>As per studies about anorexia nervosa and bulimia nervosa, the following similar characteristics include being fearful of becoming obese, substance abuse and low self-esteem. Low self-esteem can result in suicide attempts, therefore; the only dissimilarity among the four choices is “that they are both sexually experienced.” No report is found to match this claim, at the same time, the typical onset of both diseases occur during early teens and late teen years, so they are far from being sexually experienced. </span>
