Precambrian time, the Paleozoic era, the Mesozoic era, and the Cenozoic era
The correct answer is - increased resource supply.
The resource extraction is a process though which the supply of resources on the market is achieved. In the past century, the extraction has been increasing constantly, thus the supply of resources on the market increased significantly because the demand for the same increased significantly.
On the other hand, the extraction of resources, very often, has very bad impact on the environment. The soils are destroyed, which is especially concerning considering the fact that fertile soils are desperately needed. The vegetation is cleared or polluted to a degree where it dies out, and the water also gets contaminated. Lot of this issues are extremely serious, and urgent measures have to be taken in order for such damage to be stopped.
Explanation:
You didn't attach a picture so i'll just explain how to find the number of stomatas/mm^2.
first you find the surface by multiplying the length by the width
0.1*0.1=0.01mm^2
now you count the numer of stomatas in the picture
in0.01mm^2 you have.........................x stomatas
in 1mm you have ...............................y stomatas
y=100x
Answer:
All you have to do is list the sources you used to answer the last 8 questions, and if you did no use any, leave it blank.
Explanation:
Answer: .374 and .626
Explanation:
5. total number of alleles = 4712 + 2816 = 7528
frequencey of B allele = B allele / total number of alleles --> 2816/7528 = 0.374
6. total number of alleles = 4712 + 2816 = 7528
freq of b allele = b allele/total number of alleles --> 4712/7528 = 0.626
We can confirm our answer as correct because if we add up the answers to 5 and 6 we should get one:
0.374 + 0.626 = 1
