This chart shows the types of ground tissue and their functions. Parenchyma is labeled 1, Collenchyma is labeled 2, and Sclerenchyma is labeled 3.A 4-column table has 4 rows. The first column has entries A, B, C, D. The second column is labeled 1 with entries for food production and storage, for secretion of substances like nectar, for strength and support, for healing of plant parts. The third column is labeled 2 with entries for strength and support, for conduction of materials throughout the plant, for protection and support, for protection and support. The fourth column is labeled 3 with entries for protection and support, for healing of plant parts, for food production and storage, for strength and support.

Which row (A, B, C, or D) best matches each ground tissue with its function?

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
