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: Stratum Corneum
Epidermis. The epidermis is the thin outer layer of the skin. It consists of 3 types of cells: Squamous cells. The outermost layer is continuously shed is called the stratum corneum
Explanation:
stratum corneum
The epidermis has no blood supply and depends on diffusion from the dermal cells for its metabolic needs. The dead-cell layer of the stratum corneum provides the protection from water loss that allows vertebrates to dwell on land
The cell cycle is important because without it we wouldn’t get new cells
for growth and repair. Humans would not survive without the cell cycle.
Interphase has the cells carry out the functions that are needed to
survive and the cells that divide prepare for reproduction. Mitosis has
the cell’s nucleus divide. Cytokinesis is when the duplicated contents
of mitosis are made into two daughter cells. Without these three things
we would not be able to survive.
Answer:
The answer is- A bundling relationship
Explanation:
Bundling is defined as when a company packages some of their products or services together as a single combined unit, often for a lower price than they would charge the customers if the items are sold independently or separately. This helps to facilitate the convenient sale of products or services from one company.
An example could be if Oral-B decides to sell both their toothpaste and toothbrush together as a single combined unit at a lower price than if selling the toothpaste or toothbrush separately.
BioMark Lifesystems' arrangement with the producer of syringes and test tubes to have diagnostic substances sold to laboratories in a package along with the syringes and tubes is called bundling relationship.
