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:
Explanation: The possible genotypes from this cross are Rr, rr, Rr, and rr. So, that means two offspring will be red and two will be white. The percentage chance for each phenotype is: 50% chance for red flowers and 50% chance for white flowers.
Answer:
In the organism matter and energy also follows the law of conversion which means energy or matter can not be created or destroyed, it just changes its form in any system.
Cellular respiration is a catabolic reaction that converts chemical energy in the form of the energy that is used by the cell by breaking the complex sugar and other macromolecules into simple and smaller components and release waste products with the energy in ATP (a useable form of energy for the cell).
The energy stored in the bonds of the sugar and other organic molecules take place in this process converted into the chemical bond formed in ATP, is exactly the same only changed its form.
