Answer:
Instead of oxygen a creature would also need nutrients. Simple everyday things like water and food.
Explanation:
Although it is kind of impossible to live without oxygen. There are organisms on the earth who do not need it and can survive. They metabolize hydrogen or methane or a number of other compounds.
It will affect the wind in the future because most wind currents will converge into multiple distinct locations like windfarms. This will make wind less prominent in other locations without wind farms
Answer:
The reason why there is so much diversity of life, despite the fact that DNA is the same for all living things, the pairings are always the same and there are only six components that make up the DNA, is that sequences of base pairs are different.
Explanation:
DNA is the molecule that contains all the genetic information, whose structure consists of four nitrogenous bases, adenine, guanine, thymine and cytosine, plus deoxyribose and a phosphate group. This DNA molecule constitutes the basis of life and inheritance of all living beings.
The nitrogenous bases of DNA are found in a number and specific sequences, which determine the proteins and biomolecules that must be synthesized in the cells.
What makes different types of living beings and diversity of life is the length of the DNA and the sequence of bases that form part of each molecule.
The other options are not correct because:
- <em>The sugar component of DNA is always the same, not different.
</em>
- <em>Organisms always use DNA in the same way.
</em>
- <em>The DNA molecule is always the same.</em>
