Answer:
Homologous structures provide evidence for common ancestry analogous structures show that similar selective pressures can produce similar adaptations beneficial features Similarities and differences among biological molecules in the DNA sequence of genes can be used to determine species relatedness
The effect is due to static electricity when Lucas rubbed plastic ruler on the sweater he caused the ruler to become negatively charged due to rubbing creating a negative charge that is carried by electrons so when he waved above pieces of paper positive charges present in the atoms of paper became attracted to negatively charged ruler.
Answer:
it includes geological processes that slowly alter the layout of the physical enviroment and human activity such as land conversion which can help and alter much faster and causes the extinction of many species
Explanation:
Abiotic limiting factors restrict the growth of populations. They help determine the types and numbers of organisms able to exist within an environment. Biotic factors are living things that directly or indirectly affect organisms within an environment.
<span>Technically, a scientific theory can never be irrefutably proven. Observations that corroborate a theory and increase its credence, but can never prove it. Contradictory evidence can confute a theory, and if such a case happens, then the theory will have to be modified or replaced so that it accounts for the evidence.
The meaning of theory in a scientific sense is a little different than what is used in the common vernacular. While theory to a layman may mean little more than speculation, in scientific terminology, a theory is an explanation of the natural world that can be used in a predictive capacity and thus tested rigorously and repeatedly.
Evolution will ever remain a theory, as any theory that can be considered scientific has to be testable and refutable. However, as science has matured in the "down to earth" fields, I do not think that evolutionary theory will ever be disproven in whole, though it might be modified to account for new discoveries. These modifications will probably be very specific modifications and the general theory would still stand.</span><span>
