Answer:
The structure shown by the red arrow is cell membrane.
In biology, cell membrane refers to the thin layer, which develops the external boundary of a living cell. It has three primary functions, which are as follows:
1. It comprises channels and receptors, which permits particular molecules like nutrients, ions, metabolic components, and wastes to pass between the cell and the outside environment.
2. It prevents toxic components from entering the cell.
3. They distinguish essential but incompatible metabolic procedures conducted within the cell.
Explanation:
<span>In dna fingerprinting, the dna probe that is used is complementary to the dna sequence of the repeats.

It depends if you're talking about Physical Science or Physics/Biology -- so, I'll give both definitions (:
Physical Science: the positively charged central core of an atom, consisting of protons and neutrons and containing nearly all its mass.
Physics/Biology: a dense organelle present in most eukaryotic cells, typically a single rounded structure bounded by a double membrane, containing the genetic material.
Hope that helped! (:
The scientist is examining a disaccharide molecule.
Disaccharide is a form of sugar or carbohydrates or is an organic molecule that contains two simple sugars linked together. Like monosaccharides, disaccharides are the sugars soluble in water. Maltose, lactose, and sucrose are some examples.
Monosaccharides are joined to form disaccharide sugars through a condensation reaction, which requires the removal of a water molecule from the functional groups. A type of enzyme called a disaccharidase is used in the process of hydrolysis to separate a double sugar into its two monosaccharides.

The answer would be B. Abiotic Factors. The prefix a means not, so a biotic means not alive. Hope that helped :D
