BIOL 133 Week 4 Chapter 6 Study Questions Researchers are working to develop biofuels to free us from dependence on fossil fuels. Based on what you know about cellulose, what do you predict are the major advantage and disadvantage of using cellulose-rich plant material as biofuel? What examples describe the second law of thermodynamics? Select all that apply. Neostigmine is a drug used to treat the disease myasthenia gravis.

BIOL 133 Chapter 18 Week 14 Study Questions 10.0/ 10.0 Points Reproductive barriers increasing over time would lead to ________. At a family get-together, your uncle says “I don’t believe in that evolution stuff. Scientists are always saying that something evolved because of ‘a gene for eyes’ or ‘a gene for wings’. Well, that’s crazy – how can one single gene build an eye or a wing?” How do you reply? In the process of adaptive radiation, there is usually one species fr...

BIOL 133 Week 13 Chapter 17 Study Questions An individual may have a mutation that causes them to break down a drug much more quickly than normal people. They were then provided with a higher dose, which was effective in treating the disease. This is an example of ________. Isolating all of the RNA out of an organism, subjecting it to reverse transcriptase, and then cloning all of the resulting DNA into plasmids is the process of creating A change in the level of an individual protein in a ...

BIOL 133 Chapter 16-wk 12 Study Questions A gene is made up of three exons (numbered consecutively) with two introns (intron 1 between exons 1 and 2 and intron 2 between exons 2 and 3). What would happen if there were a mutation at the 3’ splice site of intron 1? _________ is the first protein to bind to mRNA to being the initiation of translation. In eukaryotes, where would a protective modification be found on mRNA? The portions of the mature mRNA where RNA-binding proteins can attach ...
