When gaining biodiversity, occurs when a new resource is introduced to a species and individual members of that species begin to specialize in the resources that are available.

a.) geographical isolation
b.) polyploidy
c.) bottlenecking
d.) competition

Answer;

C.) Bottlenecking

-When gaining biodiversity, bottlenecking occurs when a new resource is introduced to a species and individual members of that species begin to specialize in the resources that are available.

Explanation;

-The Bottleneck Effect occurs when there is a disaster of some sort that reduces a population to a small handful, which rarely represents the actual genetic makeup of the initial population. This leaves smaller variation among the surviving individuals.

-Genetic drift can cause big losses of genetic variation for small populations. Population bottlenecks occur when a population's size is reduced for at least one generation.

The correct answer is D.) competition

Explanation:

When any new resource is introduced into the habitat of a species and each single members of that species begin to specialize in that resource than competition will start between the members of species because as the number of individuals that utilize the new resource increase the amount of new resource availability per individual will decrease.

So as the availability of the new resource decrease per individual of species more intra-species competition will occur between them to get the resource for their survival. Therefore the right answer is D. competition.

water is a polar molecule. a chemical bond is a force of attraction between atoms or ions. bonds form when atoms share or transfer valence electrons. atoms form chemical bonds to achieve a full outer energy level, which is the most stable arrangement of electrons. so, false

explanation:

in h2o molecule, two water molecules are bonded by a hydrogen bond but the bond between two h - o bonds within a water molecule are covalent. the greater the electronegativity difference, the more ionic the bond is. bonds that are partly ionic are called polar covalent bonds. nonpolar covalent bonds, with equal sharing of the bond electrons, arise when the electronegativities of the two atoms are equal.
