Answer:
C, the specimen will appear fuzzy and have poor resolution
Explanation:
Immersion oil is used in a microscope to improve image quality. The oil has a high refractive index that allows light concentrate on the specimen (prevent light from away from the specimen).
Russia's population density is 8.4 people per square kilometre (22 per square mile), making it one of the most sparsely populated countries in the world.
The presence of the gauze, or lack thereof. (Independent Variable)
Also technically the the Dependent Variable, which is whether or not maggots appeared.
He also did a second experiment; the independent variables were the open jar (often called the control nowadays), the jar covered with gauze, and the jar covered with cork.
The dependent variables would be again, the appearance of maggots. They appeared in the uncovered one, appeared on the gauze covered one, but did not survive, and were absent on the cork covered one.
Answer:
DNA is essentially a storage molecule. It contains all of the instructions a cell needs to sustain itself. These instructions are found within genes, which are sections of DNA made up of specific sequences of nucleotides. In order to be implemented, the instructions contained within genes must be expressed, or copied into a form that can be used by cells to produce the proteins needed to support life.
The instructions stored within DNA are read and processed by a cell in two steps: transcription and translation. Each of these steps is a separate biochemical process involving multiple molecules. During transcription, a portion of the cell's DNA serves as a template for creation of an RNA molecule. (RNA, or ribonucleic acid, is chemically similar to DNA, except for three main differences described later on in this concept page.) In some cases, the newly created RNA molecule is itself a finished product, and it serves an important function within the cell. In other cases, the RNA molecule carries messages from the DNA to other parts of the cell for processing. Most often, this information is used to manufacture proteins. The specific type of RNA that carries the information stored in DNA to other areas of the cell is called messenger RNA, or mRNA
