The difference between pH 3 and pH 4 is a 10 fold difference in the concentration of H+
Of the following given choices;
A. glacial erratics B. U-shaped valleys C. unusually shaped rocks D. mudslides.
The answer is; C.
The wind carries soil particles is it blows. These soil particle hit on rocks in their path and over time gradually erode the rocks. An example of this type of erosion is the aeolian process. Usually the bottom o the rock is eroded more than the top. This is because the bottom is hit by larger soil particles that are heavier to carry by the wind. An example of rock formed in this process is attached in the picture below.
The answer is B
A keystone predator would increase niche diversity and help reduce niche competition <span />
Answer:
Red allele frequency will be highest in population II
Population III can undergo bottleneck effect
The frequency of the brown allele will least likely be altered in the population I
Explanation:
Population I -
Total population -
Brown birds -
Red birds -
Population II
Total population -
Brown birds -
Red birds -
Population III
Total population -
Brown birds -
Red birds -
Frequency of red birds in population I
Frequency of red birds in population II
Frequency of red birds in population III
Red allele frequency will be highest in population II and it will be equal to as compared to in case of population I and III
Population III can undergo bottleneck effect because of smaller population size
The frequency of the brown allele will least likely be altered in the population that has highest brown individual , i.e population I
