Hello! i think the answer is possibly a? ? , you so !
which of the following best explains a way that a molecular clock can be used?

the number of dna mutations in an organism is measured over time to determine how long it will take for a new species to evolve.

the number of dna mutations in a species is compared to the number of dna mutations in another species to determine the relative amount of time each species has been evolving.

the number of differences in a specific dna sequence of two species is multiplied by a known mutation rate to determine the number of years of evolution that separate the two species.

the number of differences in the dna sequences of two organisms of the same species is averaged to determine how many years of evolution have occurred.

Which of the following scenarios is an example of the bottleneck effect? answers a in south africa, much of the afrikaner population is descended from a small number of dutch colonists. in this population, this is an unusually high frequency of pseudoxanthoma elasticum (pxe), an elastic tissue disorder. b four white-tailed deer are introduced to a park in finland. thirty years after their introduction scientists compare the genes in the population and find that there is no variation. c during the industrial revolution, london's air became filled with soot. as a result, birds started eating more of the lighter moths because they were easier to spot than their darker counterparts. over time, the moth population changed so that there were more darker moths than lighter ones. d 10% of the population of american alligators in an area have the recessive trait albinism. a massive flood results in the death of 80% of the population. of the remaining population, 60% have the recessive trait of albinism.

Protein synthesis actually begins in the nucleus when transcribes a single gene on the dna molecule is copied. the process of copying this gene is called this copy is known as and contains the protein building instructions. this copy is sent out into the cytoplasm to the part of the cell known as the the of the ribosome will join together to form a functional ribosome when they attach to the mrna. as the mrna moves through the ribosome, the message is read by transfer rna brings the correct back to the ribosome. the amino acids are placed in the correct order and are hitched together by

What is the relationship between absorbance of light and the rate of photosynthesis?
