With regard to the tube with no sucrose, how would you classify the situation in terms of a solvent movement ( isotonic, hypotonic, or hypertonic)? Explain

Consider the two solutions separated by an ideal semipermeable membrane (permeable to water but impermeable to solute).  Assuming complete dissociation of all the salts you can expect: a.) net water movement from side 1 to side 2 b.) net water movement from side 2 to side 1 c.) no net water movement

Which Which of the following is ABSENT in a Gram-positive cell envelope? O plasma membrane O phospholipids O LPS layer glycan chains lipoteichoic acids all of these are PRESENT in a Gram-positive cell envelope Question 4 Which of the following is ABSENT in a Gram-negative cell envelope? O lipoteichoic acids plasma membrane O peptidoglycan- lipapolysaccharides all of these are PRESENT in a Gram-negative cell

Your team suggests changing the temperature of the oil spill site in order to enhance the bioremediation process. Do you consider this decision effective? Why and why not? Explain, in your answer, the effect of changing the zone tension on the homeostasis capacity of the bacteria you use and their ability to withstand the osmotic pressure of the new surrounding solvent. In your answer, state how osmosis works and state the degree of tension of the solution (isotonic, hypertonic or hypotonic). Explain why osmosis is really just a special case of facilitated diffusion
