Scientists have genetically-engineered some strains of bacteria to consume toxins, such as oil, and to excrete the toxins as harmless substances. How might these bacteria most likely impact society? A. They will cause more bacterial infections in people. B. They will grow out of control and consume the world's oil supply. C. They will cause people to become more careless about polluting the environment. D. They will enable people to easily clean up spilled pollutants in the environment.

Several bodily responses are described below. for each response, determine what caused the change in homeostasis. body starts to sweat breathing rate increases amount of saliva produced changes body starts to shiver

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
