Answer:
7 hours
Explanation:
Given, generation time of the species is 1 hour which means that after every 1 hour the cells double in number.
At 0 time = 100 cells/ml
After 1 hours = 200 cells/ml
After 2 hours = 400 cells/ml
After 3 hours = 800 cells/ml
After 4 hours = 1600 cells/ml
After 5 hours = 3200 cells/ml
After 6 hours = 6400 cells/ml
After 7 hours = 12800 cells/ml
Thus, after 7 hours the culture will contain approximately 10000 cells/ml.
Answer;
Plants control solute concentration in their bodies by regulating uptake from the soil.
Explanation;
Uptake of water from the roots is undertaken by process called osmosis. Solute concentrations increase going from soil to root cells to leaf cells. The resulting differences in osmotic pressure helps to push water upward in the plant. This helps the plant control solute concentrations.
