Answer:
When there are 5 molecules of fructose on each side of the membrane.
Explanation:
The solution will reach equilibrium fro fructose when there are 5 molecules of fructose on each side of the membrane.
A membranous system is said to be at equilibrium when there are equal concentration of a particular molecule on both sides of the membrane.
<em>Hence, for a membranous system with 10 molecules of fructose on one side, an equilibrium can only be reached for fructose when there are 5 molecules on one side and the remaining 5 molecules on the other side. </em>
Answer: Meselson & Stahl reasoned that these experiments showed that DNA replication was semi-conservative: the DNA strands separate and each makes a copy of itself, so that each daughter molecule comprises one "old" and one "new" strand. The semi-conservative model, in which each strand of DNA serves as a template to make a new, complementary strand, seemed most likely based on DNA's structure. ... From the patterns of DNA labeling they saw, Meselson and Stahl confirmed that DNA is replicated semi-conservatively.
Explanation:
Answer:
The correct answer is A from an area of higher concentration to an area of lower concentration
Explanation:
Diffusion is one of the most important membrane transport process which helps in the transport of small molecules and gases across the plasma membrane from higher concentration region to the region of low concentration until the concentration of the transported molecule becomes equal at both sides.
As the molecule move along the concentration gradient no external energy is needed to carry out simple diffusion.
