What characteristic do viruses share with all living organisms?
Replicate Viruses are simple, and not cells, they attach to a cell infect it with viral RNA than disperse. They dont metbolize, use respiration, and not all living organisms move (plant cells) but they can move depending one what virus it is Viruses evolve, mutate and replicate at an alarming rates. Its to the point where you have to get newer shots more often because the virus changes or replicates so much
How is modern genetics evidence of evolution?
Evolution is the change in allele frequency over time in a population of organisms. One of the most important things modern genetics can do is observe this fact of nature by modern evolutionary genetic sequencing of many population genomes.
What do it means When biologists speak of a universal genetic code they are referring to the fact that in nearly all organisms?
RNA specifies proteins the same way.
For what reason is evolution false?
There is no such reason. Evolution, the change in allele frequency over time in a population of organisms, is a fact and as much a fact as the sun rising in the East every day. The theory of evolution explains much about the fact of evolution and is supported by more evidence that the fact that the sun seems to rise in the East is explained by the theory of heliocenterism.
Why is genetic recombination important?
Since it's sexual two organisms give a part of their DNA to put together and so the resulting organism gets some, not all, of the traits from both starting organism. This means that after sexual reproduction the new organism will always be different from others, but have some characteristics that are the same. The new combination of characteristics can either be bad or good and this will determine survival and weather or not the combination will be passed down.
What pieces of evidence most strongly supports the common origin of all life on Earth?
Simularities in DNA sequence
Wha is the difference between relevant and material in evidence?
Relevant Fact is a fact that logically supports a proposition, Material Fact is a fact that relates to any matter in dispute between parties.
Does asexual reproduction incress or decress diversity?
Decreases diversity because asexual reproduction is almost a cloning process and the progenitor organism transmits 100% of it's genetic endowment to it's off spring while sexually reproducing organisms contribute 50% each in genetic material and, with independent assortment, crossing over a random fertilization, sexually reproducing organisms posses much more genetic diversity that asexual reproducers. In fact some biologists think that when more complex organisms go this route that they are headed for extinction. Less complex asexual reproducers have a high mutation rate and have mechanisms for exchanging genetic material laterally.
Is gay a genetic mutation?
No, in fact its not any kind of problem. It is a natural, sexual orientation.

What is and egg cell?
Gametes! They contain half the amount of genetic material that body (somatic) cells contain. BAsed on this fact, they are called haploid.
What are the differences between the fact and evidence?
Fact is something that you can prove with evidence. Evidence is what you use yo prove something is a fact.
Why is it all living things originated from a common or universal ancestor?
Because we can trace the genetic trail back that far and the fossil trail almost back that far. One genetic code shared by all organisms is rather good implicating evidence for universal common ancestor.
Which of the following is correct about eukaryotic cells?
they have a nucleus, they have a cell membrane, they are not found in plants.
