The solutions in the two arms of this U-tube are separated by a membrane that is permeable to water and glucose but not to sucro
DaniilM [7]

Answer:

The correct answer to the question is: the level of liquid in Side A will rise.

Explanation:

  • Sucrose is formed of two molecules of glucose but the membrane is impermeable to it.
  • The given membrane is said to be permeable to water and glucose.
  • Through a semi-permeable membrane, molecules tend to move from a region where its concentration is high to another region where its concentration is low by the process of diffusion until its concentration in the two regions becomes equal. This phenomenon is known as Osmosis.
  • Concentration gradient of a molecule can be defined as the difference in the concentration of the molecule in two different regions separated by a semi-permeable membrane.
  • Considering glucose, the concentration of glucose is low in side A (1M) and high in side B (2M), so it will tend to move from side B to side A down its concentration gradient.
  • Considering sucrose, although its concentration is high in side A (2M) but low in side B (1M), it is unable to move as the membrane is impermeable to it.
  • Water tend to move from a region where the concentration of solute is low (or water concentration is high) to a region where the concentration of solute is high (or water concentration is low).
  • Due to the movement of glucose from side B to side A, the concentration of total solute concentration becomes high in side A as compared to side B. Therefore, water would move from side B to side A.
  • Hence the level of liquid in Side A will rise after sometime.

Answer questions about aspects of Watson-Crick model of DNA structure
tino4ka555 [31]

Answer:

a. The directionality of the complementary strand is antiparallel. The double-stranded DNA is antiparallel comprising two strands, which run alongside each other, however, point in reverse directions. In a double-stranded molecule of DNA, the 5 prime ends of one strand align with the 3 prime ends of the other strand, and vice versa.  

b. The mediation of base pairing is done by non-covalent hydrogen bonds. It is reversible, that is, the strands can separate and can come combined again without any chemical modification.  

The specificity of base pairing is illustrated by hydrogen bonds that is, the first strand produces hydrogen bonds only with a particular base in the second strand, and these two bases produce a base-pair.  

c. The interaction or association of non-covalent type, that is, hydrophobic interaction and hydrogen bonding. Collectively, they both are strong. In the process, one base associate with the other base on the complementary strand.  

d. The phosphate backbone possesses the tendency to associate with water on the outside of the molecule, and this is favorable chemically as both the strands are held together by hydrogen bond and hydrophobic interaction.  

The polar molecules of sugar can produce hydrogen bonds with the surrounding molecules of water. The negatively charged phosphate group associate with the positively charged ions. The nonpolar nitrogen bases are found within the molecule and associate favorably through stacking interactions.

In noncyclic photophosphorylation, O2 is released from
jonny [76]

The correct answer is: B) H2O

Non-cyclic photophosphorylation is a light reaction and it occurs in the thylakoid membrane and it involves two different chlorophyll photosystem.

Non-cyclic photophosphorylation is a reaction where a water molecule is broken down into 2H+ + 1/2 O2 + 2e− . This process is called photolysis. The  2H+ and 1/2O2 from the water are left out for further use, while two electrons are kept in photosystem II.
