Answer: The earth provides natural resources, such as water, wood, arable land, fossil fuels, oil, minerals, vegetation, and air. These are all used by human societies, with many of them being vital for human life and the lives of all organisms.
Answer:
3'-TTACGATG-5'
Explanation:
The DNA sequence is in couples where A is united T and G is united C, so what we do is replace in the complementary sequence the original nucleic acids, remember A-T, G-C.
5'-AATGCTAC-3'
3'-TTACGATG-5'
To remember: the DNA sequence is 5'-3' in one sequence and its complementary is inverse, what means it goes 3'-5'.
Also the T-A is united by 2 hydrogen bonds, and G-C is united by 3 hydrogen bonds.
An ecological niche refers to an organism's specific behavior in its specific ecosystem.
There are many things that fall under this description. For example, by specifying an ecological niche, we could be talking about the behavior an organism is exhibiting when there is plenty of resources or when the resources in a certain ecosystem are scarce. This has to be taken in account together with the question whether he has to compete with other organisms in his ecosystem for those resources.
Hope this helps :)
