What is the best definition of mutation?
A mutation is a change in the DNA sequence of an organism, which can result in alterations to the characteristics or traits of the organism. Mutations can occur spontaneously or be induced by various factors such as chemicals or radiation.
What is a mutation and explain when a mutation is beneficial?
A mutation is a permanent change in the DNA sequence of a gene. This can be beneficial if the change gives a new function to or improves the function of that gene. The above is a definition. But one must really define "beneficial". Some regard it as beneficial if it helps the specific individual who has it. Others would think it beneficial if it produced some survival advantage that insured more descendents for that individual. It is the difference between a mutation that allowed for greater athletic ability, but a decreased desire for offspring, versus a more moderate athletic enhancement, but a greater desire for offspring. The small percentage of ways to improve an organism, versus the near infinite ways of harming the organism, mean that most mutations are not going to be beneficial. At best, they will be "inconsequential" - such as a new shade of eye color, or a mole on a section of your skin. The populist notion of "powers" that can come from mutations is wildly inaccurate. Even assuming a minor power like the ability to see infra red radiation would take thousands upon thousands of mutations over vast amounts of time. A mutation for blindness is far more likely. It should also be noted that the traditional model of evolutionary theory no longer applies to man. We don't allow changes in our environment, and without such changes, there is no need for one trait more than another to predominate. After all, it is irrelevent that a mutation might allow for greater speed in running, when everyone drives a car.
What best describes symbiosis?
Symbiosis is a close and long-term interaction between two different species. It can be mutualistic (beneficial to both species), commensalistic (beneficial to one species, neutral to the other), or parasitic (beneficial to one species, harmful to the other). Symbiotic relationships can involve various forms of interaction, such as mutualistic co-dependence or one organism living on or inside another organism.
What best explains why a living organism in a wet mount slide moves into and out of focus within the field of view with a microscope?
The movement of a living organism in a wet mount slide into and out of focus within the field of view is due to the organism shifting its position vertically in the water droplet. As it moves up and down, it comes into and goes out of focus at different depths of the water droplet. Adjusting the fine focus knob on the microscope helps bring the organism back into focus as it moves.

What is the importance of mutations to life on earth?
Mutation in it self, serves as the way a species adapts. Mutations can be natural or man-made/influenced. "The strong survive" that is the most important thing about mutation. But for a species to adapt it is necessary to have a diverse genetic population. When the environment changes the part of the population best adapted to the new circumstances propagate and survive best. But in general a member of a species is often able to adapt its genetics to an environmental situation. For example when people who live on sea level move to higher regions, then in a few generations the people adapt to the new environment (thinner air, less oxygen). These changes can be genetic, but not necessarily the product of evolution.
Which statement best explains the observation that clones produced from the same organism may not be identical?
gene expression can be influed by the environment
What law best explains why an organism with Tt will show only dominant phenotypic?
The law that best explains why an organism with the genotype Tt will exhibit only the dominant phenotype is the Law of Dominance. This principle, established by Gregor Mendel, states that in a heterozygous genotype, the dominant allele (T) masks the expression of the recessive allele (t). Consequently, the presence of one dominant allele is sufficient to produce the dominant phenotype, resulting in the organism displaying that trait.

How did unicellular organisms evolve on earth?
My best guess is when anything reproduces mutations may occur in the DNA. Some mutation happened in the DNA and the unicellular organism to start replicating itself. (We see call this mitosis) The mutation turned out to be a good thing and helped the organism survive, later generations through more mutations started orientating the cells into a specific shape... making a whip like tail so it could propel itself forward and so on and so on
