Answer:

This way, for 20^2.55 = 2109 amino acids are require to have 2*1056 number different sequences.

Explanation:

How much oxygen is produced (the units are milliliters of oxygen per hour) when light intensity is 0%. How do you explain these
katovenus [111]

Answer:

As light intensity increases (distance between lamp and plant decreases) the volume of oxygen (or the rate of bubble production) increases. This indicates that the rate of photosynthesis increases with light intensity. However, at sufficiently high levels of light intensity, the rate oxygen evolution remains constant.
