Answer:
Sharing electrons occurs when atoms have a covalent bond. Covalent bonds occur between non-metals and there are two types of covalent bonds: Polar and Nonpolar Covalent bonds. Polar covalent bonds are when there is an unequal sharing of electrons which causes the atom that occupies the electron(s) more to have a slightly negative charge while the atom that occupies the electron(s) less has a slightly positive charge. Nonpolar covalent bonds basically have equal sharing of the electron(s).
Atoms bond because they need to become stable like the noble gases.
Explanation:
Prevent loss of Genetic Diversity and Inbreeding
The knowledge of parentage provides one with information about the origin and identity of the parents.
The variations and changes in the genes of the progeny of the parents can also be understood by the knowledge of the parentage.
Population of wild endangered species can benefit from the knowledge of parentage as this can help in prioritizing original gene material, avoid inbreeding incidents , important tool to manage cross between species hence aiding in the prevention of genetic diversity and loss of population.
In zoos, inbreeding is very common due to small populations which can lead to an increase in homozygous populations instead of heterozygous ones. Decrease in heterozygous populations implies decrease in genetic variability.
∴ Knowledge of parentage in zoos can help with that.

The Golgi Vesicles provides the instructions.
Primary producers make their own food for example plants. As you go into the upper levels of the food chain the energy gets distributed to each level, but they lose some of their energy. Without primary producers alligators will not be able to obtain the energy they need for themselves to survive.
