Aresearcher studying a line of cancer cells notices that cellular content of rhobtb3 and cyclin e1 increase and decrease through the cell cycle.
he hypothesizes that rhobtb3 signaling regulates the production of cyclin e1 and the entry of the cell into mitosis. based on the data below, explain why his results do not support this hypothesis. identify what conclusions are supported by this data.
suppose that the researcher can engineer a cell line in which rhobtb3 expression can be induced by the addition of a drug. design an experiment using this cell line to test whether rhobtb3 regulates the production of cyclin e1. describe what results he can expect if his hypothesis is correct.

What is used to keep track of the gamates and possible offsprings combination

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

Astudent completed a lab report. which correctly describes the difference between the “question” and “hypothesis” sections of her report? “question” states what she is asking, and “hypothesis” states the result of her experiment. “question” states what she is asking, and “hypothesis” states what she thinks the answer to that question is in “if . . then . . because” format. “question” describes what she is trying to find out, and "hypothesis" states the procedures and methods of data collection. “question” describes what she is trying to find out, and “hypothesis” states any additional information or prior knowledge about the question.
