Think about the actual physical process happening in the cell - the allele (or versions of a gene) are literally physical pieces of DNA strung together into chromosomes. And as the cell divides to form gametes, those chromosomes randomly assort themselves into the two new cells (conditional that each new cell gets one copy of each chromosome, in the case of gametes)...<span>

Selective permeability is when a cell membrane allows some molecules or ions to pass through it, but not others.
The trees that are most likely to avoid extinction in such an environment
have seeds that are easily dispersed by wind or animals .
Trees which are easily dispersed by wind or animals have a very high chance of survival because the seeds dispersed will grow to form trees and if there is death of some they will still be present due to the continuous seed dispersal.
This is the main reason why the seeds with more dispersal means will not
become extinct.

Enzymes are known as catalysts in a chemical reaction, as they can reduce the time it takes for the reaction to occur by breaking things down. Enzymes are important to living things, because they can be found throughout the body to aid in things like digestion and fighting illnesses. A good example would be putting a Ritz cracker in your mouth and letting it dissolve. This happens because your mouth is full of enzymes that help break food down before entering the digestive system. Hope this helps! :)
