Two selectively permeable sacs A and B were submerged in a 45% glucose solution that was contained in a beaker. Sac A contained

a 15% glucose solution and Sac contained a 15% sucrose solution. In which direction did net movement of water molecules occur? a. Only from Sac A to the beaker b. Only from Sac B to the beaker c. From the beaker to both sacs d. From both sacs to the beaker

Answer:

Option a. Only from Sac A to the beaker is correct.

Explanation:

As beaker contains glucose which is a monosaccharide and Sac A also have glucose in it, So, therefore glucose from sac A will move into beaker through the process of OSMOSIS.

Sac A (15% glucose) is less concentrated as compared to beaker (45% glucose) therefore this phenomenon will occur. (See attached image for more detailed and graphical explanation)

AnnyKZ [126]

Answer:

gene flow

Explanation:

Gene flow, in simple terms, is a transfer of gene from one population to another. Also called as migration, where there is movement of individuals, and the genetic material they carry from one population to another. It also involves successful breeding of these individuals in their new locations. When people with sickle cell anemia were brought into the US, transfer of the gene responsible for sickle cell disease changed the frequency of the sickle cell allele in overall US population.

4a) From the sequence below, identify which portion could be a transmembrane helix. Please underline the portion you select in y
arlik [135]

Answer:

FRYVNGPVLIRKLYSWWNLIMILLQYFAIMGNLVMNLVMNTGDVNELTANTITT

The bold region of the above sequence will be in the transmembrane region.

4.b) To predict the helix we need to know the propensity of each amino acid in the amino acid sequence to form an alpha helix of the protein. Not only the propensity of a single amino acid will dictate that but also other amino acids in its vicinity will have an effect on it. More importantly, that should follow the Ramachandran plot.

4.c) I chosen that region based on the hydropathy index of the stretch of amino acids. The region of amino acids should have hydrophobic side chain because they will interact with the hydrophobic tail of the lipids in the cell membrane. So this region has higher hydropathy index than others. This lead me to choose that region.
