Scientists and nutritionists have long suspected that high-fructose corn syrup, used to sweeten soft drinks, is one of the causes of childhood obesity. In a recent study, at the University of Cincinnati, researchers found that mice that drank water with added fructose ate less solid food, gained more weight and put on 90% more body fat than mice that drank only water. Scientists concluded that fructose may affect metabolism in a way that favors fat storage.
What is the independent variable in this experiment?
the presence of fructose in their diet
the mice that drank only water
the weight gained by the mice
the quantity of water provided
the quantity of food eaten
the presence of fructose in their diet
Based on the reading below, which hypothesis would be supported by the experiment?

The mixture will fizz.
If I add baking soda to the acid, then the balloon change color.
If I add baking soda to the acid, then my balloon will inflate.
If I add baking soda to the acid, then my balloon will inflate.

In a particular plant, leaf color is controlled by gene D. Plants with the dominant allele D have dark green leaves, and plants with the homozygous recessive dd genotype have light green leaves. A purebred dark-leaved plant is crossed with a light-leaved one, and the F1 offspring is allowed to self-pollinate. The predicted outcome of this cross is diagrammed in the Punnett square shown below, where 1, 2, 3, and 4 represent the genotypes corresponding to each box within the square. Which of the boxes marked 1-4 correspond to plants with dark leaves?
1 only
1 and 2
2 and 3
4 only
1, 2, and 3
1, 2, and 3

Kilauea is a Hawaiian volcano that erupted in 1959, destroying vegetation and animal life over an area of 5 million square meters. After the eruption, scientists closely monitored the area to track the recolonization of the devastated habitat. The table below shows the changes in one localized area that was covered by a massive amount of lava rock with many cracks and crevices. Despite the colonization of the area by several different types of organisms by year 9, the overall cover of the habitat was so low that the surface still looked barren. Pioneer species are the first species to take hold in a barren area after a disaster has occurred. Based on the data, most of the pioneer species in this area were which of the following types of organisms?
A. Algae & mosses
B. Mosses & seed plants
C. Ferns & lichens
D. Seed plants & algae
A

Natural selection says:
a) populations of plants and animals in nature most often consist of individuals that are clones of each other
b) those individuals whose variation gives them an advantage in staying alive long enough to reproduce are more likely to pass their traits on to the next generation
c) populations of a species that become isolated from others by adapting to different environmental niches quickly become extinct
d) all of the above
