9 Which process is an example of facilitated transport?
AA carrier protein moves water across the cell membrane against the concentration gradient.
B A protein embedded in the cell membrane allows glucose to move to a region of lower concentration.
Waste materials from cellular processes are moved to a region of higher concentration outside the cell.
The cell membrane wraps around a large molecule and forms a a vesicle that takes the molecule into the cytoplasm.

The fauces connects which of th following structures to the oropharynx

What term describes a doctor who becomes a specialist by meeting standards beyond those of getting a license and passing a test in the specialty area?

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
