C. Temperature and pH can affect how enzymes work
Enzymes show a maximum activity at an optimum pH and temperature. Changes in the pH or the temperature can cause damage in the structure of the enzymes, if the structure changes the substrate can no longer bind to the enzyme, which is why the activity of the enzymes starts to slow down.
All choices correctly describes physical barriers. Physical barriers after composed of tight junctions wherein it is difficult for the bacteria and viruses to penetrate. Examples of these physical barriers are the skin and the mucous membranes and these work in conjunction with secretions like tears and mucus (as tears and mucus contain IgA, a special type of immunoglobulin that is secreted to fight harmful organisms).
Answer:
E. none of the above i think
Explanation:
Answer:
1 We can infer that when permeable channels are added to the peptides and a cell is incorporated in water, the concentration of peptides and water will change, generating an equilibrium causing an equivalence of equal intracellular and extracellular concentration
2. If there is no alteration and the environment is in equilibrium, we can say that there will be an equal concentration of petids and water in the intracellular and extracellular space. If we have 40 peptides on the left side, the right side will move looking for a balance and that both environments are the same, becoming 60 for each of the spaces
