Answer:
Mutation is important as the first step of evolution because it creates a new DNA sequence for a particular gene, creating a new allele.
Explanation:
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",
The answer is C, DNA sequences of populations that are closely realted
Answer:
<h2>a rift valley is forming</h2>
Explanation:
Answer: A
The cells would lose water and shrink. In a hypertonic solution, the
concentration of solute is higher than water in a cell. With this, there is a
net movement of water from inside to outside initiating water to lose from the
cytoplasm and vacuole causing the cell to shrink due to osmosis and achieve
equilibrium.
This process is applied in food preservation where microbial cells will
be dehydrated in a hypertonic environment, making them malfunction and preventing
them to cause food spoilage.
