Answer:
The correct answer is - 1990.
Explanation:
From the graph and year - population size table it is clearly understood that the population of grizzly bear is reduced by 39 number from year 1988 to 1989.
But after 1989 from 1990 onwards population of grizzly bear is consistently rising.
Now, let us analyse the data given in question number 2 .
No. of grizzly bear deaths in Alberta from 1976 to 1988 = 581
No. of grizzly bear deaths in Alberta from 1988 to 2000 = 281
From the above data we can clearly say now that the grizzly bear population deaths starts increasing from 1990.
So, the prediction made in question no. 1 that " the government of Alberta introduced the hunting lottery award in 1990 because in 1989 it decreases and then it starts to go up again in 1990",
Answer: from 30% sucrose solution to the 40% sucrose solution
Explanation:
From the definition of osmosis is the movement of water molecules through a selectively permeable membrane from a region of lower solute into a region of higher solute concentration, until the solute concentrations on the two sides is equal.
Therefore the net movement of water molecules will move from 30% sucrose solution to the 40% sucrose solution until the concentration of sucrose on both sides of the impermeable membrane is equal 35% each.
