The answer is oil.
The United States' fossil shortage of oil makes the country dependent on outside sources. Mineral oil such as crude oil or commonly known as petroleum came from the ancient fossilized organic materials. This resource is limited. The US is now facing a shortage in oil and becoming dependent to some countries such as middle-east countries.

Autotrophs, by definition, are organisms that are able to internally manufacture their own food. Autotrophs, also known as producers, are organisms that obtain their energy by converting light energy into chemical energy, via photosynthesis. Photosynthesizing plants are an example of autotrophs.
Heterotrophs, by definition, are organisms that are unable to internally manufacture their own food. Heterotrophs, also known as consumers, are organisms that obtain their energy by consuming other organisms. Humans are an example of heterotrophs.
Answer:
8 chromosomes
Explanation:
Mitosis is the process whereby a cell divides into two identical copies of itself. This genetical identity emanates from the fact that the daughter cells possess the same kind and number of chromosomes as the parent cell.
Hence, a nucleus that has eight (8) chromosomes during interphase will possess 8 chromosome in each daughter cell at the end of mitosis. Mitosis, which consists of stages, duplicate its DNA at the interphase stage but do not increase the chromosome number. Sister chromatids are formed for each chromosome, which separate during anaphase stage, and become individual chromosome in each daughter cell.
In this case, 8 chromosome are still formed at interphase but 16 sister chromatids. These chromatids separate equally into each daughter cell i.e 8 in each cell to become individual chromosomes.
