Secondary succession generally takes place faster in comparison to primary succession as the substrate is already present. In the case of primary succession, there is no soil and it consumes much time to form.

Primary succession takes place in mainly lifeless regions, that is, the regions in which the soil does not possess the tendency of sustaining life as an outcome of various factors.

On the other hand, secondary succession takes place in the regions where a community that previously prevailed have been eradicated and is epitomized by smaller scale turbulence, which do not eradicate all the forms of life and nutrients from the environment.

Organic molecules derived from vitamins that act as helpers are called

AysviL [449]

Coenzymes

Coenzymes are small organic molecules that, themselves, do not function as catalysts (i.e. enzymes) but aid the latter in carrying out their functions. Enzymes are biological catalysts, which means that they allow reactions to occur at lower activation energies. In a way, enzymes help to "speed up" chemical reactions.

Coenzymes are mostly derived from vitamins. Examples include TPP from Vitamin B1 (thiamine), FAD from Vitamin B2 (Riboflavin), and NAD+ from Niacin.

A researcher recorded that a chemical reaction required 2.90 gal water and raised the temperature of the reaction vessel by 57 F

Bess [88]

A. 11.0 L is the researcher's volume measurement to the SL units of liter

Explanation:

Given that a researcher recorded that the chemical reaction has water = 2.90 gallon.

We have to convert the researcher's volume into the SL units of liter.

So, we know that 1 gallon = 3.875 liters.

Then we have to convert 2.90 gallons of water in to liters.

Then , volume in L = $(volume\ in \ gal) \times (3.875 L/1 gal)$ = $(2.90) \times (3.875L/1 gal)$
