Which statements accurately reflect the permeability of the cell membrane? choose all that apply. the hydrophilic part of the cell membrane is a, the phosphate head. the lipid tails are hydrophobic and will only allow molecules which are small and polar to pass through. molecules that are large or charged must use a channel protein, such as d, to cross the cell membrane. molecules using membrane proteins, such as e, for transport require energy. charged molecules, such as k+ or ca++ are unable to pass through the lipid bilayer because of their charge and must use a membrane protein to cross the cell membrane. c, the lipid tails, are hydrophobic and repel water.

liquid crystals are matters in a state which have properties between those of conventional liquids and those of solid crystals[1]. liquid crystal is partially ordered and anisotropic. in terms of molecular order, liquid crystal molecules have one-dimensional or two-dimensional long - range order.

lysosomes contain a variety of enzymes, enabling the cell to break down various biomolecules it engulfs, including peptides, nucleic acids, carbohydrates, and lipids (lysosomal lipase). the enzymes responsible for this hydrolysis require an acidic environment for optimal activity. hope i !

enzyme speed up the reactions

enhanced global partnerships and exploration capabilities may advance international preparedness for protecting the earth from catastrophic events such as some asteroid strikes, advancing collaborative research on space weather and protecting spacecraft by developing new means for space debris removal.
