Which is more likely to develop adaptations to a changing ecosystem a population that often has many mutation or a population that has few mutations?
A population with many mutations.
Can mutations be beneficial?
They can certainly be either. When researching it closely scientists have found a lot of mutations which don't seem to have any influence. "Bad" mutations tends not to be functional, and often disappear pretty much by themselves one way or another.
How can mutations be detrimental to an organism?
They are not always harmful. in fact, often they are not. There are many different mutations, but genetic mutations can occur and be harmful to humans. it is important to understand that Genes are not there to cause diseases or be harmful. if a gene is transcribed incorrectly or copied incorrectly, this can result in a single letter of DNA ommitted in a chain. This is harmful because the different parts of the body that transcribe DNA or RNA will not be able to transcribe it as it was intended to be transcribed.
Which in DNA often occur during replication. During which phase of the cells cycle do such mutations occur?
Interphase
Mutations that cause dramatic changes in protein structure are often?
your mom is what causes the answer, Frameshift mutation.
Does dried blood contain microorganism?
Dried blood can contain microorganisms. However, these organisms that can be found in dried blood are most often no longer living.
What are some characteristics of the Drosophila Melanogaster?
Drosophila melanogaster is a small fly that is often found near fruit. They are often know as fruit or vinegar flies. The flies have red eyes and are a yellowish color.
What microorganism often causes disease on the skin or nail?
Bacteria!!
Mutations in DNA often occur during replication During which phase of the cell cycle do such mutations occur?
Interphase
How often do mutation occur?
Mutations are constantly happening.
What is parasitic microorganism?
Parasitic organisms are those that live at the expense of other organisms. Often, parasites feed on other animals. For example, mosquitos are parasites because they feed on the blood of other living things. Mosquitoes sometimes carry parasitic microorganisms too, like plasmodium falciparum, which is the protozoan that causes malaria.

What is auxotrophy?
Auxotrophy is the inability of a microorganism to synthesize an organic compound required for its growth, often as the result of a mutation.
People who have been exposed to excessive radiation often experience mutations If these mutations only occur in somatic body cells these people may?
experience an increased risk of cancer
Effects of uv light on growth of organisms?
As ultraviolet rays are mutative i e they cause a cell to change its inherited status so they are most harmful next to the anihilation of the cell and organisms are bunches of cells
