Alex787 [66]

Answer:

They will have a large amount of genetic variation.

Explanation:

Scrapping pollens obtained from one plant to the flower of another plant (different variety but same species) would lead to increase in the genetic pool. The new hybrid plant would carry genetic features from both plants varieties. This process is also used to develop new varieties and have been recognized as cross-pollination. This process is generally preferred over genetic modification (GM) because of more nature friendly.

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.
