Answer:
Option b. Lowering the pH to kill pathogenic bacteria is correct answer.
Explanation:
bacterial motors are sensitive to pH. By decreasing the pH bacterial motors stops working. This was identified in a new research. But, with the weak acids and a lower internal pH they slow and ultimately stop moving (became dead).

Answer:
Poor drainage or improper watering
Explanation:
Water issues — either too much or too little — are the leading reason behind yellow leaves. In overly wet soil, roots can't breathe. They suffocate, shut down and stop delivering the water and nutrients plants need. Underwatering, or drought, has a similar effect.
Store and transmit genetic information: nucleic acid
Are primarily used to store energy: lipids
Help regulate cell processes: proteins
Are used for main source of energy: carbohydrates
Answer:
Genetic code
Cadons
Explanation:
genetic code is the code that allows an organism read the information in it genes. The information provide instructions for building and operating a living organism.
The genetic code is a combination of sequential nitrogen base A, G, U, C formed in the mRNA chain. These four bases is what make of the letters of the genetic code which combine together to form the cadons
