Answer is D. The phosphate group of membrane lipids are negatively charged.
The cell or plasma membrane is a bilayer of phospholipids. The two phospholipids layers are opposite to each other. Each phospholipid molecule consists of a phosphate group and a lipid. The phosphate form inner and outer layers of hydorphilic and are negatively charged 'heads' and lipid forms the tail, hydrophobic and non-polar. Since phosphate is negatively charged it repels negatively charged molecules and do allow them to pass through it.
A chemical that is used only on inanimate objects and cannot be safely ingested as antimicrobial is sanitizer
Sanitizers are the chemicals used to destroy the disease causing pathogens from the inanimate objects. These substances are generally bleach like or different proportion alcohol solutions. The basic way they work is by dissolving the protein layer of the microbe and exposing its content leading to its death.
These sanitizers may also contain some essential oils to aid the skin in staying hydrated and not dry when used. During the corona times it helped to prevent the spread of virus as people regularly used it to get rid of any germs.

Answer:
I think how species are related is because of their blood and how they are alike from other breeds
Explanation:
Answer:
The pumping method of sodium-potassium pushes sodium and potassium ions against elevated concentration levels. It transfers two potassium ions into the cell where the levels of potassium are high, and pumps three sodium ions into the extracellular fluid and out of the cell.
Explanation:
ATP's hydrolysis is an active transport mechanism by the passage of sodium and potassium ions across the cell membrane to provide the required energy.
