Which hypothesis provides the best explanation as to why the moth population change over time?
The hypothesis that the moth population change is due to natural selection favoring moths with traits that provide better camouflage against a changing environment is the best explanation. This is supported by the observation that moth coloration has shifted over time to match industrial pollution levels, showing adaptation to survive predation.

What does hypothesis mean on changing double color flowers?
A hypothesis on changing double color flowers could be a proposed explanation or prediction about how altering growing conditions, genetics, or environment may impact the color expression of the flowers. It serves as a basis for experimentation to test the theory behind the change in color.
Why is evolution considerd a theory?
Evolution, the change in allele frequency over time in a population of organisms, is a fact. The theory of evolution by natural selection explains much of this fact. That is what a theory is. A consistent explanation of a phenomenon, or a series of phenomenon, that is supported by massive amounts of evidence, containing both facts and laws and is able to make predictions that generate testable hypothesis. A theory, in the scientific sense, is not a guess.
What is genetic equilibrium and how does it describe a population in which the allele frequencies remain constant and do not change over time?
Genetic equilibrium is a state in which the allele frequencies in a population remain constant and do not change over time. This means that the population is not evolving and there is no change in the genetic makeup of the population.
How are a theory and a set of hypotheses related?
As long as you haven't scientifically proven that a statement you make or a phenomenon you describe is actually true and repeatable all over the world, then you may call this statement a hypothesis. It is something you personally believe in, but the rest of the world will not believe you unless you test your hypothesis and prove it right. (Needless to say, if your test results prove your hypothesis wrong, then you need to start over and rephrase the hypothesis.) After repeated empirical testing with getting the same results every time, and when you believe your hypothesis is right, then you might announce your findings to the world by presenting a theory. This theory is accepted by your peers, but only if they get the same results under similar conditions in their own labs. And if your theory is truly revolutionary, resulting in a so-called change of paradigm, then you may expect a Nobel prize at some point.Answer 2:A hypothesis is a guess or proposed explanation for an observed phenomenon. It's a starting point for further investigation. A theory is much more substantial. To become a theory, after the hypothesis is proposed it is tested in various ways. For example, theories can be used to make predictions which can then be tested. And, a after testing a theory has not been contradicted by these tests.
What describes the transformation hypothesis of evolution?
Answer 1Transformation hypothesis:Evolution is the change in allele frequency over time in a population of organisms.This is an observed and observable fact.Natural selection is the nonrandom survival and reproductive success of randomly varying organisms. This is a theory, not a hypothesis.Natural selection is the adaptive change driver of evolution by adapting individuals to their environment so they are reproductively more successful than their con-specifics and their genes are more frequently represented in the next generations of the population; evolution.Answer 2To my knowledge, there is no such thing as the "transformation hypothesis of evolution". Especially note that evolution does not describe any kind of transformation, but a process of undirected, gradual change over generations. Using the term 'transformation' might instil inaccurate ideas about what evolution is, and what evolutionary theory states about it.
Explain null hypothesis versus alternative hypothesis?
The null hypothesis is that there is no change in the population mean while the alternative hypothesis is that there is a change in the mean. The null hypothesis is stated as Ho:Mu=? in statistics while the alternative hypothesis is stated as Ho:Mu(<,>,≠)? depending on whether you are looking for mu to be greater, less than, or not equal to population mean.
How do you revise a hypothesis?
you change the hypothesis.
What do scientist do when their data does not support their hypothesis?
Discard or change the hypothesis.
What happens when the data doesn't support the hypothesis?
Change or abandon your hypothesis.
What does it means when scientist develop a theory?
'law' is an observation about how things behave, or tend to behave, without an explanatory framework. i.e., Newton's laws of gravity, Kepler's laws of planetary motion, the laws of thermodynamics. These are essentially factual observations about how the universe behaves. A hypothesis is a proposition that forms an explanatory framework about the phenomena. It must explain observations, and provide a testable, falsifiable explanation for why the phenomena exist. For example the theory of stellar evolution started out as a hypothesis that explained how stars form, change over time, and how they die, and it provides specific testable predictions for future observations. A theory is a hypothesis that has gathered supporting evidence, and has been accepted as a valid explanation for phenomena. It's a hypothesis, all grown up. The key is the difference between the use of the word 'theory' in science and common language. 'Theory' does not mean 'guess' or 'supposition' in science. A valid theory is a widely accepted explanation of phenomena. In the example above, the hypothesis of stellar evolution gathered sufficient supporting evidence for it to be considered a valid theory.
What type of hypothesis for the effects would change in the ozone layer have on Antarctican's penguins population?
A hypothesis could be: "A decrease in the ozone layer leads to increased ultraviolet radiation exposure in Antarctica, which negatively impacts the food sources of penguins, ultimately reducing their population size."
Can a hypothesis change?
No, because it is a statement with a history, if it is wrong it is superseded by a new hypothesis.

What options does a scientist have if experiment does not support hypothesis?
a scientist can do another experiment or change their hypothesis.
