Answer:
There are two types of ecological succession:
Primary succession:
Primary succession occurs in areas which were previously devoid of life. There were no organisms living in this area before. For example, lands after new glaciers or volcano eruptions. Firstly, microorganisms begin to habitat this land, followed by plants like lichens, shrubs etc. Finally, complex life evolved from these.
Secondary succession:
Secondary succession arises in areas where life existed before but was destroyed due to natural circumstances like flood, fire etc. Small grasses inhabit this land first which are taken over by trees over period of time.
Answer:
CGTCATC
Explanation:
In a DNA double helix, the complementary bases of two strands of DNA are paired by hydrogen bonds. Adenine of one DNA strand is paired with the thymine of the other strand. Similarly, the guanine of one DNA strand is paired with the cytosine of the other DNA strand. If a portion of one of the two strands of a DNA molecule has the sequence GCAGTAG. The sequence of the other strand would be as following:
One DNA strand: GCAGTAG
Other DNA strand: CGTCATC
I believe passive transport is a form of diffusion. And it doesn't require any energy unlike active transport.
