The light mice can reproduce more successfully than the dark mice

The graphs below show the changes in crab color at one beach.
Which of the following is most likely to have caused the change in the distribution?
A new predator arrived that preferred dark-tan crabs.
A new predator arrived that preferred light-tan crabs.
A change in beach color made medium-tan crabs the least visible to predators.
A change in beach color made medium-tan crabs the most visible to predators.
The figure shows how natural selection of a single-trait gene affects lizard survival.
Which of the following most likely causes the changes in allele distribution?
The allele for light gray coloration disappears from the population. This may be because light gray lizards are more visible to predators and therefore they might be less likely to survive and reproduce.
The allele for black coloration decreases fitness and becomes less common. This may be because black coloration keeps the lizards cool during hot summer temperatures.
Medium gray coloration in lizards appears to be a neutral mutant allele that allows the lizards to hide better from predators. This leads to increases in phenotype and allele frequency of gray coloration.
Because black and medium gray lizards are less visible to predators, these alleles are neutral to natural selection and therefore will not disappear from the population of lizards.
Grass plants in a population range in height from 6 cm to 25 cm. The short plants receive little sunlight, and the tall plants are eaten by grazing animals. Which statement best describes the effect of natural selection on the grasses?
Because average height grass plants are favored, stabilizing natural selection is occurring.
Because average height grass plants are favored, disruptive natural selection is occurring.
Because tall grass plants are favored by the animals that eat grass, directional selection is occurring.
Because short and tall grass plants are favored, normal natural selection is occurring.
