Explanation:
The polar nature of the membrane’s surface can attract polar molecules, where they can later be transported through various mechanisms. Also, the non-polar region of the membrane allows for the movement of small non-polar molecules across the membrane’s interior, while preventing the movement of polar molecules, thus maintaining the cell’s composition of solutes and other substances by limiting their movement.
Further explanation:
Lipids are composed of fatty acids which form the hydrophobic tail and glycerol which forms the hydrophilic head; glycerol is a 3-Carbon alcohol which is water soluble, while the fatty acid tail is a long chain hydrocarbon (hydrogens attached to a carbon backbone) with up to 36 carbons. Their polarity or arrangement can give these non-polar macromolecules hydrophilic and hydrophobic properties i.e. they are amphiphilic. Via diffusion, small water molecules can move across the phospholipid bilayer acts as a semi-permeable membrane into the extracellular fluid or the cytoplasm which are both hydrophilic and contain large concentrations of polar water molecules or other water-soluble compounds.
Similarly via osmosis, the water passes through the membrane due to the difference in osmotic pressure on either side of the phospholipid bilayer, this means that the water moves from regions of high osmotic pressure/concentration to regions of low pressure/ concentration to a steady state.
Transmembrane proteins are embedded within the membrane from the extracellular fluid to the cytoplasm, and are sometimes attached to glycoproteins (proteins attached to carbohydrates) which function as cell surface markers. Carrier proteins and channel proteins are the two major classes of membrane transport proteins; these allow large molecules called solutes (including essential biomolecules) to cross the membrane.

Kesav will Planting nitrogen-fixing crops, such as peas, in rotation with wheat crops can dramatically reduce the variability of farmers' income with a high-yield, high-protein harvest. ... Instead, they depend on the presence of nitrogen as ammonium or nitrate ions in the soil.
B) A node would be introduced.
This would be used to help provide distinctions to these species
1) Eat to get nutrients (plants undergo photosynthesis)
2) Cell division was observed.
3) They infect cells to reproduce
4) In the lytic cycle the viral DNA incorporates into the host DNA
5) It gets your body ready to fight a specific virus (i.e. flu shots)
6) prokaryotic (although some are capable of forming an envelope made of proteins)
7) Archebacteria, Eubacteria
8) stimulus
9) DNA or RNA and a protein coat
10) One kingdom has different chemicals that make up the cell wall. (Archea lack peptidoglycan)
11) Many archebacteria live in harsh environments. (halophiles, thermophiles, etc.)
12) cholera
13) poultry
14) asexual reproduction (self replicating)
15) the ability of an organism to keep its internal conditions suitable for life
16) photosynthesis (get glucose from water and CO2)
17) virus (question #9)
18) Wendell Stanley
19) flat pentagons (they're not cubes but rods)
20) cholera (cause by Vibrio cholerae)
21) influenza
22) acidic lemon juice (all other methods kill bacteria).
