Subatomic particles include electrons, the negatively charged, almost massless particles that nevertheless account for most of the size of the atom, and they include the heavier building blocks of the small but very dense nucleus of the atom, the positively charged protons and the electrically neutral neutrons.
And I don't see any of the particles. so I can only answer the first one.
The term, selectively permeable, refers to the fact that the membrane allows some substances or molecules to enter the cells, and others to be prevented from entering. It also allows substances to leave the cell. All of this is dependent on the size of the molecule and the concentrations on either side of the membrane.
Selectively permeable membranes are important in maintaining homeostasis, fluid and electrolyte balance, and cellular health. Cells need to receive glucose and other nutrients in order to carry on normal cellular processes, and eliminate waste products of metabolism to avoid the accumulation of cellular toxins which can disrupt cellular processes and lead to cellular death.
P.s this is not my answer
Answer:
A substance that is dissolved in a solution is called a solute
Explanation:
Solute is the substance which is dissolved
Solvent is where you dissolve the solute (usually liquids)
Solution = Solute + solvent
Nitric oxide is a colorless gas with the formula NO. It is one of the principal oxides of nitrogen. Nitric oxide is a free radical, i.e., it has an unpaired electron, which is sometimes denoted by a dot in its chemical formula
