Fossil Record - Provides proof by exposing the details of a ancestor for compared to the living one.
Geographical Distribution of Living Things - a pattern of the ancient existing species, isolated land and islands have their own species of plants and even some animals.
Similarities in Development - Charles Darwin used the science of embryology to test many species within a class to find out that they are similar even if the adult version looks completely different.
Molecular Similarities - its believed that natural selections isn’t the reason for evolution actually its the genetic drift of mutant alleles that are neutral.
I hope this is good
It's natural from the sun and it doesn't use any of the earths resources therefore saving the environment
I think that the best answer is first one:
a) Trace the path that the sound waves travel as they enter the ear and proceed to the receptor cells for hearing, making sure to explain the process of transduction.
I think the answer would be because if there is an error in the DNA replication, it would affect one generation of cells. if the error would fall in the transcription or translation, there would only be one cell affected.
Cation-exchange chromatography is used when the molecule of interest is positively charged, the stationary phase is negatively charged and positively charged molecules are loaded to be attracted to it. So, the amino acids with negative charge will elute the first. Glutamate, leucin, arginine is the order of elution because of their pI values ~3, ~6 ~10.
