Gregor Mendel conducted experiments with pea plants and studied traits such as plant height, pod color, and seed shape. He recorded data on how these traits were inherited from one generation to the next. In 1865, Mendel identified the existence of factors that appeared to be inherited in predictable patterns.
The factors that Mendel described in his studies are known today as -
variations
chromosomes
genes
mutations

Monarch butterflies are known for their vibrant wing patterns, which are slightly different among individuals within the species. Some butterflies have wing patterns that are bright orange with black edges, some have darker coloration with darker veins, and others have unusual markings or spots.
These observable differences in the wing patterns of butterflies are -
variations
genes
alleles
mutations

Sunlight causes the skin to produce more melanin, the pigment responsible for skin color. This extra melanin helps protect the skin from harmful ultraviolet radiation by absorbing and scattering the light.

Before the Industrial Revolution, the majority of peppered moths were light-colored. During the Industrial Revolution, soot from factories darkened the tree trunks, which led to a change in the population of dark-colored moths. The images show the peppered moth populations before and during this period.
Explain the change in the dark colored moth population
The dark-colored moths had the advantage of camouflage on the darker tree trunks.

While Charles Darwin was on the Galápagos Islands, he observed different species of finches that were similar but lived on different islands. He noticed that the warbler finch had a more pointed and narrower beak than many other species.
Which statement most likely describes the reason for the difference in beak shape?
The warbler finch’s beak became narrower in response to drought.
The warbler finch needs a pointed beak for defense against predators.
The warbler finch originated from a different species of bird.
The warbler finch’s beak is an adaptation to the food available in its habitat.

A litter of kittens usually has siblings that look different from one another. The kittens have the same parents but do not look the same.
Which statement best describes why the kittens do not look identical to each other?
Each kitten was produced through asexual cloning.
Each kitten was produced through sexual reproduction.
Some kittens have DNA from only one parent.
All kittens are a result of genetic mutations
Each kitten was produced through sexual reproduction.

A student takes notes and lists characteristics of sexual and asexual reproduction.
I. Requires little time and energy for reproduction.
II. Results in a larger number of offspring.
III. Requires a great deal of time and energy for reproduction.
IV. Offspring are genetically identical to the parent organism; clones.
V. Results in a smaller number of offspring.
Which student notes accurately describe sexual reproduction?
III, V

Male bowerbirds build and decorate elaborate nests to attract females. These nests are called bowers and are decorated with objects such as flowers, shells, and plastics. Male bowerbirds also perform dances and sing as part of their mating rituals.

They are physiological adaptations that increase their chances of reproductive success.
They are physiological adaptations that decrease their chances of reproductive success.
They are behavioral adaptations that increase their chances of reproductive success.
They are behavioral adaptations that decrease their chances of reproductive success.

A widow’s peak is a V-shaped point in the hairline. The allele for a widow’s peak hairline is represented by W, while the allele for a straight hairline is represented by w. A child receives a W allele from his mother and a w allele from his father. The child’s combination of alleles is Ww.
Based on this information, what type of hairline will the child have?
The child will have a widow’s peak hairline.
The child will have a straight hairline.
The child will have a combination of a widow’s peak and a straight hairline.
The child will not have a hairline that follows typical inheritance patterns.
The child will have a widow’s peak hairline.
