The switching from lysogenic to the lytic cycle, also called lysogenic induction, can be caused by a double-stranded break in the prophage or can be caused by a mutagen. These factors could cause disruption of the cI & cro genes that are responsible for regulating the lytic-lysogenic cycles of bacteriophages..
The rain gauge is an instrument used by meteorologists to measure the amount of precipitation in a particular region in a particular amount of time.
The rain gauge is placed on the ground in order to collect the rain or the precipitation sample. The rain gauge is labelled with the quantities, which can be used to measure the amount of precipitation.
So, the correct answer is option (a). on or near the ground.
Answer:
The correct answers are A. "crenation", B. "hemolysis", C. "hemolysis", D. "crenation" and E. "neither will occur".
Explanation:
0.9% (m/v) NaCl or 5.0% (m/v) glucose are isotonic solutions at which the cells will not suffer any harmful consequence. A solution with a higher concentration than the isotonic conditions would result in the cells crenation, while a solution with a lower concentration would result in the cells hemolysis. Therefore the consequences of putting the red cells to the solutions stated in the question are as following:
A: 3.21% (m/v) NaCl Solution = crenation (higher than 0.9% (m/v) NaCl)
B: 1.65% (m/v) glucose Solution = hemolysis (lower than 5.0% (m/v) glucose)
C: distilled H2O Solution = hemolysis (lower than 0.9% (m/v) NaCl or 5.0% (m/v) glucose)
D: 6.97% (m/v) glucose Solution = crenation (higher than 5.0% (m/v) glucose)
E: 5.0% (m/v) glucose and 0.9%(m/v) NaCl = neither will occur (equal to 5.0% (m/v) glucose and 0.9% (m/v) NaCl)
