4. look at the graph below which shows the results of a drugs trial with 6000 patients. 3000 patients were
riven a tablet containing statins, 3000 were not. both groups were given advice on changing their lifestyle
and diet
without
statins
with statins
a) describe the two conclusions that can be made from the results
b) what is the name given to the group that were not given statins?
c) what would they have been given instead?
d) give one reason that the results of this trial would be considered to be reliable
5. look at the graph below.
compare the incidence of disease for the different weight groups. don't forget to include data.

Which is true of transition metals when moving from left to right on the periodic table? the d sublevels are not filled across the period. the cation radii become larger across the period. atomic radii increase slightly and then start to decrease. atomic radii decrease slightly and then start to increase. o

Calculate the change in entropy if br2(l) is converted to br2(g). s° for br2(l) = 152.2 j/(mol•k) s° for br2(g) = 245.5 j/(mol•k) s° for br(g) = 175.0 j/(mol•k)

Hannah is writing a report on how albedo affects the global climate. she’s proofreading her passage for any factual errors. which sentence must hannah correct before submitting her report? earth receives energy from the sun. this energy drives many of the processes on earth, including its climate. some part of this energy is reflected by earth’s surface. we use the term albedo to describe the reflected energy. albedo of an object is the ratio of the reflected radiation to the total radiation reaching the object. a value of 0 means no energy is absorbed by the object, whereas a value of 1 means that all of the energy is absorbed. in this way, the albedo of an object can influence earth’s atmospheric temperature.
