3. Which of the following statements indicate why the cell theory is a theory instead of a law?
A. The cell theory is the result of explanations of scientists' observations and not a
description of the cell structure as it relates to the function.
B. The cell theory is the result of the accumulation of much empirical scientific data, which
is not required for a scientific law.
C. The theory explains what happens to cells under certain conditions while laws are proven
hypotheses.
D. The theory has not been supported by enough scientists to become a law.

You will create a molecular clock model for an arthropod gene. follow these guidelines to make your model: . your timeline will span from 90 million years ago to the present. the common ancestor in your model is an arthropod that lived 90 million years ago. the gene that you'll track codes for a protein in the species venom . the dna sequence youll track contains 10 nitrogen bases. you can choose the order of the bases and where the mutations occur. this gene mutates at a rate of approximately 0.76 base pairs every 17.1 million years. to build your model,/ calculate the estimated time period it takes for 1 base pair to mutate. the first time period will only show the common ancestor. at the beginning of the second time period, three lineages will diverge from the common ancestor, each with a different mutation in their gene sequences. the first and third descendant species will survive for the rest of the timeline. the second descendant species was extinct 50 million years ago. calculate how long it will take for one full base pair mutation to occur. explain your reasoning by constructing a mathematical equation
