Answer:
Water molecules
Explanation: 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 their concentration gradient, by simple diffusion. Small nonpolar molecules, such as O2 and CO2, are soluble in the lipid bilayer and therefore can readily cross cell membranes. Small uncharged polar molecules, such as H2O, also can diffuse through membranes, but larger uncharged polar molecules, such as glucose, cannot.
Answer:
<em>Asexual Reproduction</em>
Explanation:
Reproduction is the process of producing new offspring by the parents. Reproduction is of two types namely, the sexual or asexual type. This is a character only possessed by living things.
Asexual reproduction is the type of reproduction that occurs with a single reproductive cell. The offspring produced in this type of reproduction looks the same as the single parent. Asexual reproduction comes in many forms namely;
- Binary fission
- Budding and;
- Fragmentation
Answer:
results in an even distribution of molecules
It's false. the runoff will increase the fertilizers in the stream, because it takes whatever is siting on the surface.
Answer:
The cell membrane would keep expanding in a way that could lead into a process called apoptosis.
Explanation:
As said on the question, in secretion, the same amount of membrane must return to the cell, because, when a cell wants to send something to outside of it, it needs to have a membrane involving it for protection, and the organelle that does that is the Golgi Apparatus.
Once it involves this thing that needs to go outside the cell, this Golgi will be less larger than before, and the plasmatic membrane will be bigger once the exocytosis happen, and if it keeps expanding and not going back, the golgi apparatus would stop working and this cell would program its own death by the apoptosis process.
