Thank You So muchhhhhhhhhhhhhhhhh!
Answer:
Soap solution functions to dissolve the cell membranes, alcohol is used to precipitate DNA, and Gatorade is a isotonic solution.
Explanation:
In the DNA extraction protocols, the cell membranes that are formed by lipidic bilayers can be dissolved by using detergent solutions that are functionally analog to soap solution, shampoo, etc. On the other hand, alcohol enables to precipitate DNA (because DNA is not soluble in alcohol), while proteins and other cellular components remain in the extraction solution. Finally, Gatorade is a isotonic solution that may be used to prevent the cells from lysing.
The labeled anatomical features of the muscle filament are attached as an image.
Muscle filament or Myofilaments are the two protein filaments of myofibrils in muscle cells. The two proteins are myosin and actin and are the contractile proteins involved in muscle contraction.
- It has two filaments, a thick one made up mostly of myosin, and a thin one composed mostly of actin
- Actin is a filament made up of protein that contributes to the contractile property of muscle. It is found in two forms, G-actin (monomeric globular actin) and F-actin (polymeric fibrous actin)
- Tropomyosins are contractile proteins that regulate contraction in both muscle and non-muscle cells with help of myosin and actin filaments. It is present in animal cells.
- A troponin complex is a group of three proteins, troponin T, troponin I, and troponin C, subunits located on the thin filament of the contractile apparatus.
Thus, the correct labeled anatomical features of the muscle filament is attached as an image.

The gaps (approximately 1 micrometer wide) formed between myelin sheath cells long the axons are called Nodes of Ranvier. Since fat serves as a good insulator, the myelin sheaths speed the rate of transmission of an electrical impulse along the axon.
