Prior to a fatty acid (FA) being used as the input for beta-oxidation, it is activated and transitions from cytosol to mitochondria.
How is the FA activated and how is the activated FA is sent to the mitochondria matrix. Also explain how the breaking down of the FA in B-oxidation ends up producing big amounts of ATP (need to describe multiple metabolic reactions here)

How is the dn/ds ratio used when testing whether allele frequency change resulted from selection vs drift?

A key understanding of how synapses work is that they must be able to 1. Turn a signal on, 2. Turn a signal off again. Explain why two neurons, one dopaminergic, one glutergic demonstrate this principle in Cocaine addition. In Nicotine addiction, the pathway is reversed, a Cholinergic neuron is followed by a Dopaminergic neuron. The same logic applies. Explain.
I am an addict. Which is my best excuse? 'It’s my genes'. 'It’s my mates'. 'It’s down-regulation of my receptors'. The excuse must be accompanied by an explanation.

make a table of important vitamin facts. At the top of the document list your demographic (age/sex) category. In the table, include the following information for all vitamins (there are 13 - see Chapter 9 & 10)
FORMAT - choose a format that works for you. You may use either of the vitamin table templates (one is an excel file, one is a word doc) provided on the Chapter 9 page as a guide for what information to include in your table or make your own.

what would happen to the cells of a plant if it was watered with salt water from the ocean.( the cells of the plant would end up being surrounded by saltwater)
a. the amount of water in the plant cell would not
change.
b. the plant cells would gain water .
c. the plant cells would lose water.
d. osmosis will cause water to flow from the hypertonic plant cell
to the hypotonic solution surrounding the cells.
e. osmosis would change the plant cells such as the plant is now
adapted for a salt water environment.
