Answer:
This question is asking to fill in the blank spaces with the correct terms. The correct terms to the four blank spaces are:
1) GEL
2) DYE
3) DNA MARKER
4) LID
Explanation:
This question is describing the Gel electrophoresis technique which is used to separate DNA fragments using electric current. The DNA fragments of different sizes migrate through a GEL which serves as the matrix made from Agarose.
In order to physically see the samples that we put in the gel, we first have to add DYE to each sample of DNA. After loading the samples to be separated, a substance made up of DNA fragments of known sizes referred to as DNA MARKER, which acts as the standard curve in a tube is used.
Before running the gel, it's important to make sure that there is LID covering the gel in the gel rig. This will make sure that the electrical current runs through the gel and the gel stays cool.
The cornea is a transparent membrane which bends or retracts the light to focus the light through the pupil
The second refraction occurs in the lens which help focus the image on the retina
The retina is light sensitive cells that lines the inside of your eyes it contains cells called rods and cones. Rods are sensitive and detect dim light while cones detect brighter light and colors
All cells of multicellular organisms have similar needs. The similarity in the needs of these cells have resulted to the similarity in the structure and organelles of the cells. The general structure is that there is a surrounding membrane around a solution containing enclosed genetic material, a powerhouse, and a protein synthesis area (animal cells).

Answer:
To eliminate alternative explanations for the results of an experiment.
Explanation:
The scientific experiments include all the procedure and observations that are observed during the experiments. The scientific experiments explain about the correct scientific information.
The particular hypothesis is tested by the scientific experiments. The experiments include controls and the variables. The variable that are used as hypothesis is not controlled and the results are matched directly. The other variables are controlled as this includes the other alternative explanation of the particular result.
Thus, the correct answer is option (C).
