Can proteins diffuse through the cell membrane? Although ions and most polar molecules cannot diffuse across a lipid bilayer, many such molecules (such as glucose) are able to cross cell membranes. Channel proteins form open pores through the membrane, allowing the free passage of any molecule of the appropriate size. How do proteins pass through […]

What happens to the frequency detected by the observer as the source of the sound moves farther away? A higher frequency is received by the observer moving toward the source, and a lower frequency is received by an observer moving away from the source. In general, then, relative motion of source and observer toward one […]

Does number of moles change with temperature? 1 Answer. Well, your equation contains the same number of moles either side, so temperature does not matter. So, if the reactant side has more moles than product side, the number of moles will be increased. What happens when you have a change in moles of gas? Avogadro […]

What are your weaknesses as a CNA? My strengths are focus and drive. Though my patient load can get heavy sometimes I still get all my work done with all my patients well cared for and happy. My weakness is that I get quite attached to my patients and find it difficult to deal with […]

What is the best name for CaF2? CALCIUM FLUORIDE What is the name for a compound formed between calcium and fluorine? This insoluble solid adopts a cubic structure wherein calcium is coordinated to eight fluoride anions and each F− ion is surrounded by four Ca2+ ions (Fig….Calcium Fluoride. CAS number 7789-75-5 Molecular formula CaF2 Molecular […]

Which type of force is nuclear force? Nuclear forces (also known as nuclear interactions or strong forces) are the forces that act between two or more nucleons. They bind protons and neutrons (“nucleons”) into atomic nuclei. The nuclear force is about 10 millions times stronger than the chemical binding that holds atoms together in molecules. […]

Why is carbon monoxide removed? Carbon monoxide (CO) is a colorless, odorless gas that is emitted from combustion processes. 1 Thus, the removal of CO may also contribute to a more stable climate by helping to reduce the amount of greenhouse gases in the atmosphere. How Carbon monoxide can be removed from a mixture of […]

What is definition of equilibrium? Equilibrium is the state in which market supply and demand balance each other, and as a result prices become stable. The balancing effect of supply and demand results in a state of equilibrium. What is the best definition of equilibrium? 1 : a state of balance between opposing forces or […]

How does an enzyme perform catalytic activity with substrate molecule? Enzyme Function An enzyme can perform catalytic activity on the substrate by either arranging the substrate in a manner that is favorable for reaction, separate charge across a molecule, or induce strain to force the molecule to react with another in the active site. What […]

What elements are most likely to form anions? Halogens always form anions, alkali metals and alkaline earth metals always form cations. Most other metals form cations (e.g. iron, silver, nickel), whilst most other nonmetals typically form anions (e.g. oxygen, carbon, sulfur). Which atom is an anion? Anions. Anions are the negative ions formed from the […]
