Answer:
1- A species can migrate over long distances because they have metabolisms suitable for that, adaptation mechanisms to withstand different adversities. They usually do it to be able to reproduce in ideal climaxes or feed on certain living things or plant species.
2-The existence of oil fields, or oil towers for the manufacture of fuel.
3-Implement electric cars or batteries that do not depend on fuels such as diesel, naphtha.
Explanation:
In this exercise it is good to highlight that during the migration of animals of different species their numbers decreased both to reach the territory to which they migrate and by human intervention in nature in a harmful way.
Answer:
A. 1' ... 5'
Explanation:
The pentose sugars present in nucleotides have five-carbon structures. Other components of a nucleotide are a phosphate group and a nitrogenous base. The nitrogenous base in a nucleotide can be a purine or pyrimidine. The purine bases are covalently joined to the 1' carbon atom of the pentose sugar at their N-9. The bond between the nitrogenous base and a pentose sugar is called the N-beta glycosyl bond.
Similarly, N-1 of a pyrimidine base is covalently linked to the 1' carbon of the pentose sugar. The phosphate group of a nucleotide is bonded to the 5' carbon of the pentose sugar.

Glucoza poate fi transformată în amidon, grăsimi și uleiuri din motive de depozitare. Se intenționează să se creeze celuloză pentru pereții celulari și diverse contraens pentru reparații.</span>
Answer: The nervous system acts like a highway that transmits information to and from the brain. It communicates what parts of the body might need or not need certain things so that they can be sent to their respective destinations.
These are all digestive enzymes.
