Answer
When testing the effect of temperature on pepsin enzyme activity, the results showed that pepsin worked best at the temperature 30 °C. When the temperature decreased to 22 °C, the enzyme activity decreased sharply. Turbot and redfish retained almost half of the activity at low temperatures (5 °C).
Answer: the genes that produce the enzymes needed to break down lactose are not expressed
Explanation:
The lac operon is a series of genes used in digestion the sugar lactose. The operon is controlled by a promoter that regulates all of the genes
See full answer below.
The rapid depolarization phase
of myocardial contractile cells is due to the Na+ ions. Sodium ions are essential
for regulation of blood and body fluids, communication of nerve impulses, heart
activity, and metabolic purposes. Physiologically, it survives as an ion in the
body. Sodium is needed by
animals but is not needed by plants. The human prerequisite for sodium<span> must be less
than 500 mg per day. </span>
