Symbiosis is the relationship of 2 organisms. The 3 major types are commensalism, mutalism, and parasitism. Hope that this helps!

Symbiosis is close relationships between species.
The three types are Mutualism, Commensalism, and Parasitism.

Mutualism is a symbiotic relationship in which both organisms are helped.
For example, butterflies and flowers. The butterflies get food and the flowers get pollinated.

Commensalism is a symbiotic relationship where one organism benefits whilst the other remains unaffected.
An example of this is remora and sharks. Remora attach themselves to the sharks to protect itself and to get food by eating the leftovers of what the shark has eaten. Meanwhile, the shark doesn't care. It isn't hurt but it isn't harmed.

Parasitism is a symbiotic relationship in which one of the organisms benefits by harming the other.
An example of this is ticks and dogs. The ticks gain nutrients by taking nutrients from dogs (and other animals). The ticks are helped and the dogs are harmed.

Mutation is the source of differences in the dna code.

What is Mutation?

A mutation is a permanent change in the DNA sequence of an organism.Errors in DNA replication during cell division, exposure to mutagens, or viral infection can all cause mutations.
Somatic mutations (which happen in body cells) cannot be passed on to offspring, whereas germline mutations (which happen in eggs and sperm) can.
Damaged DNA can change by base pair replacement, deletion, or insertion. The majority of the time, mutations are benign, unless they result in tumor growth or cell death. Cells have developed systems for repairing damaged DNA due to the deadly potential of DNA mutations.

Need help ASAP:( What is the relationship among evolutionary mechanisms and genetic diversity?

marishachu [46]

Answer:Evolution and diversity result from the interactions between organisms and their environments and the consequences of these interactions over long periods of time. Organisms continually adapt to their environments, and the diversity of environments that exists promotes a diversity of organisms adapted to them.
