Small population usually cant find a mate or be able to continue a species.
Answer:
Why is internal Fertilisation important to animals?
Internal fertilization has the advantage of protecting the fertilized egg from dehydration on land. The embryo is isolated within the female, which limits predation on the young.

Explanation:
Helium is the second most abundant element in the universe, but here on earth, it's rather rare. Most people guess that we extract helium from the air, but actually we dig it out of the ground. Helium can be found in certain parts of the world, notably in Texas, as a minor component in some sources of natural gas.
Helium is generated underground by the radioactive decay of heavy elements such as uranium and thorium. Part of the radiation from these elements consists of alpha particles, which form the nuclei of helium atoms. ... Helium can also be produced by liquefying air and separating the component gases
When the gas contains more than about 0.4% helium by volume, a cryogenic distillation method is often used in order to recover the helium content. Once the helium has been separated from the natural gas, it undergoes further refining to bring it to 99.99+% purity for commercial use.
The true statements are:
1) Catabolism is the process in which complex substances are broken down, yielding a net output of energy.
Catabolism reactions break down macromolecules (lipids, proteins, nucleic acids and sugar) into smaller units that can be used for further reactions, for energy, for the synthesis of new polymer molecules or be simple waste products.
2) Metabolism is an integrated system in which many of the same reactions participate in degradative (catabolic) and biosynthetic (anabolic) pathways.
Metabolism combine all chemical reactions of an organism. Functions of metabolism include: providing energy form food molecules, synthesis of building blocks of the cell, elimination of the waste products.
3) Anabolism involves the synthesis of polymeric biomolecules and complex lipids from monomers such as fatty acids and nucleotides.
Anabolic reactions are opposite of those in catabolism: these reactions require energy (endergonic processes) for the synthesis of necessary molecules for the cells. That energy is the product of catabolic reactions.
