I believe it is its reproduction rate
a. the production of bubbles by the plant when it is in darkness
Explanation:
The indirect observation that will show that the gas produced in this experiment is oxygen is by observing the bubbles on the surface of water in darkness.
Oxygen gas is a by product of photosynthesis. Photosynthesis occurs in the dark and when there is light.
If we observed the bubbles over water, it shows that oxygen gas is given off and the water plant is photosynthesizing. This is a good way to observe the oxygen gas indirectly.

Algae grow when they have the right conditions such as adequate nutrients (mostly phosphorus but nitrogen is important too), light levels, pH, temperature, etc. Generally the amount of phosphorus controls the amount of algae found in a freshwater lake or water body. The more nutrient-enriched a lake is, typically the more algae in the lake.

well just do it i belive in you dont try to act all diffrent or cool that makes people not like u just be yourself
For both actin and microtubule polymerization, nucleotide hydrolysis is important for controlling the growth of a microtubule.
Polymerization dynamics enable microtubules to adopt rapidly changing spatial arrangements and, in some cases, perform mechanical tasks according to cellular needs. Microtubules harness the energy of GTP hydrolysis to drive a unique polymerization mechanism called dynamic instability.
Microtubules are one of the main components of the cytoskeleton and are rigid hollow rods approximately 25 nm in diameter. microtubules. are made up of dimers of α- and β-tubulin which polymerize to form microtubules, which are composed of 13 protofilaments assembled around a hollow core.
