Answer:
Electrons Can Donate - 0
Electrons Can Receive- 2
Valence - 2
Explanation:
The electronic configuration of oxygen is 
. Thus in the p-orbital there is deficiency of two electrons. Hence, it can receive/share electron but it cannot donate electrons. This makes oxygen as a good electron acceptor. Since there is a deficiency of two electrons in the outermost shell of oxygen, the valence of oxygen in thus -2
Variations in evolution usually refers to variation of genes at a particular loci. This differs from diversity which is the total of genetic differences within a population. Speciation is the reproductive isolation of a subset of a population.

Adhesion is the force of attraction between two dissimilar molecules or substances, and Cohesion is the force of attraction between two similar substances or molecules. An example for adhesion is the force of attraction lying between the walls of xylem vessels and the water molecules, and an <span>example for the cohesion forces is the force of attraction between the water molecules.</span>
Answer:
The bedbugs began to die, but then they mutated to become immune to the chemical being used on them, so then they were able to regain their population. Most of the time, in order to get rid of bedbugs, people just burn their mattress' because bedbugs mutate and become immune fast becase their life cycle is so short.
