Food is transported in both upward and downward directions.
Answer:
Peroxidase activity increases and then decreases.
Explanation:
Peroxidase activity is greatly affected by the pH factor. Peroxidase works best at the pH of 7 while decrease or increase in pH will adversely affected its activity. So when change occurs from a moderately acidic environment having pH near 6 to a basic environment, the peroxidase activity increases when reach to neutral but decreases when go further to basic environment so we can say that peroxidase activity greatly affected on the pH of the solution.

DNA mutations create genetic variation.
They could have no visible effect, no affect at all or cause something to happen, e.g cancer, or genetic mutations in the gametes lead to genetic variation in offspring. They can also lead to genetic diseases, for example cystic fibrosis or Huntingtons disease
