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.

Answer:
4 red : 0 white
Explanation:
R R
r Rr Rr
r Rr Rr
Since the dominant allele is RR this means that it will always be red

The ground is hard because it is frozen
The air is cold
B is your answer hope this helps
Answer:
Chloroplast is the organells for photosynthesis in plants and algea.It contains the pigments chlorophyll.which is made up of photosystems.The major functions of chloroplast therefore is to serve as solar energy trapping center for fixing of CO2 for CHO productions. It also serve as the center of generation ATPs through chemiosmosis for Calvin Cycle.
2.True. The lysosomes - bag, contain some digestive enzymes for braking down organic materials,wornout organelles, and even the whole cells in a process called autolysis. This explains the reason why it is called the .
3.True.This is autolysis, or cell death.It occurred when the lysosomes burst and releases the hydrolytic enzymes which digested the entire cellular structure.This may me be responsible for the decay of organisms at death.
