Possible contaminate will be Proteus or Salmonella. To differentiate the two genera urease test can be accomplished. However, urease test, Proteus will produce a positive test result.
This test can be done to determine the ability of an organism to split urea. The principle of urease test is that urea is the product of decarboxylation of amino acid. Splitting of urea via hydrolysis will produce ammnonia and CO2. The CO2 produce allows the formation of bubbles.
Answer:
Aa, bb
Explanation:
Recall that this question calls our attention to the theory of evolution as postulated by Charles Darwin. Species that are well adapted to their environment are more likely to survive, reproduce and pass on these favourable characteristics to their offspring.
In this case, the coral reefs are pink and pink Isopod species with small bodies are likely to escape the predators. Hence the genetic combination Aa(pink body) and bb(small body) are more likely to survive and reproduce.

The answer is B. Antidiuretic
hormone is the major hormone that regulates the amount of water in the body
which is based on electrolyte balance. The high-salt diet will increase the
electrolyte concentration in the blood hence ADH hormone will increase to
enable increased re-absorption of water in the kidneys. This is achieved by increasing aquaporin 2 channels in the
distal tubule and collecting tubes of the
nephrons that are responsible for water reabsorption. ADH acts in conjunction with aldosterone that regulates the
concentration of sodium ions in the blood.

The presence of cell wall, and large central vacuoles differentiate a plant cell and animal cell. Animal cell doesn't have those
