Biological structures like DNA, proteins and cells all depend on molecules. ... Neurotransmitters like epinephrine are pretty simple molecules, but without them our nervous system couldn't work. Oxygen, containing just two oxygen atoms, is a very simple molecule, and it is certainly essential to living things.
The amino acid sequence in protein from the gene fragment for botana curus
is the same with species Z that is valine, histidine, leucine, threonine, proline,
glutamine and glutamine. Meanwhile, species X and species Y has different amino
acid sequence compared to botana curus. Therefore, species Z is most closely
related to botana curus because both species has the same amino acid sequence
and has similar sized DNA fragments.
Answer:
The used up all their resources too fast and weren't able to regrow them in time; they eventually basically killed each other off.
Explanation:
A genus is composed of a number of similar SPECIES.
The animals who live in those habitats have adjusted to the local temperature so changing the climate drastically, may upset the living organisms there:)
