The one-time pad (OTP) is a theoretically unbreakable cipher. However, in practice it is of limited usability because it requires a pre-shared key of at least the same length as the message. This tool helps you encode or decode one-time pads if you have the key.

After Mendel’s discoveries were
accepted, scientists realized that traits passed to offspring were the result
of genes being passed from parents to offspring. This is an example of the law
of inheritance. The genes that are passed down from the parents are being
shared by the offspring. It can be shown if the trait is recessive or dominant
from the parents’ gene.
Coevolution is the method by which two or extra kinds emerge in tandem by exercising selection forces on each other. Coevolution happens when two or more species reciprocally influence each other's development.
