They protect the skin from attacks by predators, parasites and other injuries.
The answer is <span>There will be a shift toward the reactants.
</span>To solve this problem, it is necessary to understand Le Chatelier's principle. According to the principle, if a chemical reaction undergoes changes in conditions, the chemical equilibrium will shift in order to undo the effects. In the reaction <span>N2 (g) + 3H2 (g) </span>⇄<span> 2NH3 (g), when hydrogen gas is added to the reaction mixture, the concentration of chemicals will increase in the mixture. The system will try to decrease the concentration by removing H2, so the equilibrium will be shifted toward the reactants.</span>
Answer:
Octopuses are really strong swimmers and can get about quickly, but some species have been found to 'walk' along the seabed instead. Although octopuses need water to breathe, they can survive on land for a few minutes.

Chromium is already being used in the medicine industry to treat cancer (ovarian cancer in the form of chromium phosphate). So chromium may be used to build the efficiency of cancer treatment and make it more cost-efficient.

Replication occurs in three major steps: the opening of the double helix and separation of the DNA strands, the priming of the template strand, and the assembly of the new DNA segment. During separation, the two strands of the DNA double helix uncoil at a specific location called the origin.
