Which statement best describes what would happen to a sample of red blood cells if they were placed in a hypotonic solution? a. nothing would happen, your cell is in homeostasis, so functions would continue as normal. b. the cells would swell and possibly burst (lyse) because a build up of sugar and oxygen inside the cell would occur. more and more sugar and oxygen would be added to the cell until it pops. c. the cells would swell and possibly burst (lyse) because there is more water than solutes in the hypotonic solution compared to the cell, so the water would move in to the cell to reach equilibrium. d. the cells would shrivel up because there is more water than solutes in the cells, so the water would leave the cell to create equilibrium.

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
