PLEASE HELP ASAP IN A RUSH!!!!What do osmosis and diffusion have in common? A. Both are the net movement of randomly moving mole

cules that makes concentration nearty equal on both sides of a bilayer membrane. B. Both processes occur through a semipermeable membrane called a concentration gradient C. Both require the additional energy provided by an energy-carrying molecule, like ATP, to allow molecules to pass through the membrane. D. Both permit molecules of any kind, whether solute or solvent, to cross the bilayer membrane.

The right answer is A.

Osmosis is a phenomenon that considers only the exchanges between two liquid solutions of different concentrations in liquid phases separated by a semi-permeable wall. Osmosis is a phenomenon of diffusion of matter, demonstrated when solvent molecules pass through a semi-permeable membrane separating two solutions whose solute concentrations are different; the overall transfer of solvent is then from the least concentrated solution (hypotonic medium) to the most concentrated solution (hypertonic medium) to equilibrium (isotonic media).

The diffusion of matter, or chemical diffusion, refers to the natural tendency of a system to render uniform the chemical potential of each of the chemical species it contains.

Chemical diffusion is an irreversible transport phenomenon that tends to homogenize the composition of the medium.

During diffusion, when the concentration of molecules on both sides of a membrane is the same, the molecules will stop moving across the membrane

Further Explanation:

The transport of molecules can either be active or passive transport. Passive transport refers to the movement of the ions or other molecules across the membrane without any input of the energy.

Passive transport can be of 3 types:

  • Simple diffusion
  • Facilitated diffusion
  • Osmosis

The process of diffusion is movement of a molecule or substance from higher concentration of an area to lower concentration area. Mostly diffusion occurs in gases and liquid. This process is very important for living things. The concentration gradient is referred as difference in the concentration of substance. The process of Diffusion cease when the concentration of molecule or substance is equal in both region.

Osmosis refers to the spontaneous movement of the solvent particles via a semi-permeable membrane from a lower to the higher region of concentration, in the direction which tends to maintain equilibrium onto both sides.  

For a cell to live, the ion concentrations outside and inside the cell should be same. Also, the water content is limited because higher concentration of water can burst and swell the cell. Osmosis is crucial in the biological systems as the membranes are semi permeable. Also, focus on maintaining the equilibrium on both sides and prevent bursting of the cell.

Similarity between both the processes is that they allow the movement of solution or gases from high to low concentration. The concentration gradient acts in both processes to maintain equilibrium.

Based on the definitions of pharmacophore and privileged structure, outline essential structural features a 1,4-dihyrdopyridine
stiv31 [10]

Answer:

Explanation:

Pharmacophore (pharmacology) - The molecular framework responsible for a drug's biological activity. According to IUPAC — A pharmacophore is the ensemble of steric and electronic features that is necessary to ensure the optimal supramolecular interactions with a specific biological target structure and to trigger (or to block) its biological response.

Privileged structures are defined as molecular frameworks which are able of providing useful ligands for more than one type of receptor or enzyme target by judicious structural modifications.

1) The 1,4-dihydropyridine ring is present in many biologically important molecules that acts as an important scaffold for cardiovascular drug - a calcium antagonists and although it is technically not considered as a pharmacophore, it is considered as a privileged structure.

1,4-Dihydropyridine (DHP), belongs to the class of calcium antagonist that inhibits the influx of extracellular Ca+2 through the L-type voltage-dependent calcium channels.

A positional substitution in the 4-position is feasible in the heterocyclic ring which in turn culminates in various calcium channel antagonist activities and this heterocyclic ring is the common feature for various pharmacological activities such as anti-inflammatory activity, analgesic activity,

antihypertensive, antianginal, antitumor, antitubercular activity and antithrombotic .

Position on the heterocyclic ring binds to the L-type channel and also to N-type channel on membranes.

2.) The bioisosteres are not a suitable bioisostere for the traditional C-4 aryl or heteroaryl substitution which is necessary for calcium ion blockage thereby inhibiting it to function with the mechanism shared above.

Which cell is unspecialized? blood cell stem cell epithelial cell gamete
Free_Kalibri [48]
<span>Stem cells. There are two types of stem cells: adult stem cells - these are unspecialised cells that can develop into many (but not all) types of cells. Embryonic stem cells - these are unspecialised cells that can develop into any type of cell. And that's all! ;)

Hope this is useful !!!^_~!!!</span>
