The answer would be B as penicillin is derived from Penicillium fungi.
WATER WILL MOVE OUT OF THE CELL CAUSING IT TO SHRIVEL. This is because, the more solute a solution contain, the less its probability of crossing a semi permeable membrane into another compartment, this then result in the net flow of water from the region of lower solute concentration to the region of higher solute concentration. Thus, water will flow out of the cell which has lower solute concentration into the surrounding solution which has higher concentration. The outflow of water will make the cell to shrivel.
Answer:
The correct answer is option A) "0.0 mM sucrose".
Explanation:
Since single-celled Paramecium use their contractile vacuole to osmoregulate upon hypotonic environments, it is expected that a condition where no sucrose or salt is added is the condition where the contractile vacuole would be most active. In this extremely hypotonic condition cells tend to absorb high quantities of water, the contractile vacuole pumps water out of the cell to regulate its osmotic pressure.
Answer:
The mutated protein would be the target for the new drug therapy.
Explanation:
Cancer occur due to mutation in some important genes that regulate cell cycle as well as cell division.The mutation of tumor suppressor gene such as retinoblastoma,p53,PTEN etc also leads to the onset of cancer.
Now the most important point to note that mutation in the these particular genes result in the formation of abnormal proteins or disease causing proteins.These mutated proteins are the principle cause for the occurrence of cancer.
As a result the mutated protein would be appropriate target for the new drug therapy .The drug will interact with the mutated protein and blocks the toxic activity of the later.
