9) Which line from the passage best supports the idea that the genome
of other animals, in addition to the platypus' genome, can help
scientists learn to improve human health and resistance to disease?
A)
omparing genomes of similar species may point to
new strategies for conserving rare and endangered
species of animals.
B)
Australian scientists got platypus DNA from a female
named Glennie, from the Glenrock Station region of
New South Wales.
More generally, though, studying how nature cuts
and pastes gene modules gives scientists an inside
scoop on how genetic changes relate to health and
disease risk
D)
Although lactation is an ancient reproductive trait,
mammals - including the platypus - are unique in
their ability to produce milk that is extraordinarily
nutritious, containing a rich blend of sugars, fats, and
proteins

3one of the biggest impacts a building has on earth is the energy it uses. currently, most of the world’s energy comes from burning fossil fuels. these fuels are dirty and when they are burned they pollute the air and water. one way to burn fewer fossil fuels is to reduce the amount of electricity a building has to use. passive solar heating, which uses heat from the sun, reduces the amount of fossil fuel used to heat buildings. passive solar heating requires a south-facing wall made of glass. when sunlight shines through the wall, it is collected and used to warm the building. another way green buildings reduce their electricity use is to install other energy sources. for example, some green buildings use panels that turn energy from the sun into useable electricity. which is the best summary of paragraph 3? a) fossil fuels are dirty and pollute the air and water. most of the world's energy comes from these fuels. b) the biggest problem of buildings is that they use fuel that is dirty for heating. they need to do something to be more energy efficient. c) panels that turn energy from the sun into electricity and passive solar heating can stop the burning of fossil fuels which pollute air and water. d) since fossil fuels are dirty and pollute the air and water, other technologies that pollute less and produce energy have been developed like solar energy and green buildings.
