The likely use of coating fish with salt is to stop the growth of bacteria by reducing the moisture content (option B).
<h3>What is preservation?</h3>
Preservation is the judicious and wise use of resources to prevent them from spoilage or harm caused by pests and diseases.
According to this question, Ridha observed that fishes were coated with salt and kept in tray in the fish market.
Based on the above description, the method of preservation used is salting, which is act of sprinkling salt, either on food, or on an icy road to reduce moisture content of the substance.
Therefore, the likely use of coating fish with salt is to stop the growth of bacteria by reducing the moisture content.

Answer:
The electrical and diffusion potentials for K+ will be equal in magnitude and opposite in direction.
Explanation:
The cell potential may be defined as the potential difference between the inside of the cell and outside the cell. This difference is important for the transmission of nerve impulse.
The equilibrium condition may be defined as the condition at which the exit and the entrance of the ions will be equal. As the information in the question, Only potassium ions will move inward and outward of the cell. The potassium ions will move in opposite direction since the equilibrium has been reached.
Thus, the correct answer is option (D).
The sample that is being discussed in the problem can be either DNA or RNA.
DNA and RNA are both very important molecules. Both of these hold immense value in biology since they store all the vital information required for living. The basic structures of the two are quite similar; the only difference is that DNA is double-stranded while RNA has a single strand.
DNA and RNA molecules both contain a five-carbon sugar (ribose), a phosphate group, and a nitrogenous base. Except for cytosine, guanine, and adenine, the fourth part is the phosphate group that exists in both. RNA has Uracil while DNA has Thymine.
Since it has not been mentioned here what the fourth part might be, the sample might be a DNA or an RNA molecule.

They both are heterotrophs. Both are multicellular eukaryotes. Both reproduce sexually. Both have mitotic and meiotic cell division. Hope this helped=)
A theory of evolution that states that a species evolves in spurts of rapid change and then goes through periods of no change is known as <span>punctuated equilibrium.</span>
