Nucleotides in DNA contain four different nitrogenous bases: Thymine, Cytosine, Adenine, or Guanine.
Pyrimidines: Cytosine and Thymine each have a single six-member ring. Purines: Guanine and Adenine each have a double ring made up of a five-atom ring attached by one side to a six-atom ring.
Substrate concentration affect enzyme activity -
1. There is more enzyme activity at higher substrate concentrations due to more collisions between enzyme and substrate until a maximum rate is reached
2 Once the maximum reaction rate for the enzyme is reached, the reaction rate levels off.
The enzymatic reaction depends on various factors including temperature, substrate concentration, concentration enzyme, and other factors. The rate of a chemical reaction is affected by the total number of enzymes as well as the concentration of substrate
- Increasing substrate concentration increases the activity of a corresponding enzyme
- After a certain point, the rate of activity will cease to rise regardless of any further increases in substrate levels as the environment is saturated with substrate and all enzymes are bound and reacting to the maximum limit.
- A high concentration of substrate causes increases in a collision between enzyme and substrate.
- Collisions bring substrate molecules and enzymes together and increase enzymatic activity.
Thus, Substrate concentration affect enzyme activity -
1. There is more enzyme activity at higher substrate concentrations due to more collisions between enzyme and substrate until a maximum rate is reached
2 Once the maximum reaction rate for the enzyme is reached, the reaction rate levels off.

Answer:
Convection
Explanation:
The process where molten magma rises and sinks due to the temperature difference is known as CONVECTION.
This occurs when the hot magma moves upward and is cooled and moves downward again to be heated due to temperature difference, and similarly when cold magma moves upward and is heated and moves downward again to be cooled due to temperature difference.
Hence, in this case, the correct answer is CONVECTION
Answer:
While epidermal tissue mediates most of the interactions between a plant and its environment, ground tissue conducts the basic functions of photosynthesis, food storage, and support.
