This type of response happens instantly when your brain receives a signal from a sense receptor, like blinking when something flies toward your eye.
immediate change in behavior
This type of reproduction requires two parents and creates offspring with a unique combination of genetic material.
sexual reproduction
In a tallgrass prairie, grazing animals like bison perform this action that helps new grass seeds reach the soil and find space to grow.
spreading seeds and opening new spaces for germination
In the guppy study, predators caused this color of male guppies to increase in the population over several generations because those fish were harder to spot.
dull colored
This type of evolution occurs when two completely unrelated species independently develop similar traits because they live in similar environments.
convergent evolution
When a sense receptor sends information to the brain and that information is kept over a long period of time, it is stored as this.
memory
In asexual reproduction, a single organism produces offspring that are genetically identical to itself. These offspring are also called this.
clones
Wildfires in a prairie ecosystem remove this layer covering the ground, which allows sunlight to reach new plant shoots.
dead plants and leaves
This is the process by which traits that improve survival are passed on more often because organisms with those traits live long enough to reproduce.
natural selection
Flying squirrels and sugar gliders both have this feature that allows them to glide between trees, yet they developed it independently from each other.
flap of skin (called a patagium) stretching between their front and back legs
These specialized structures in your body detect changes in the environment and send signals to your brain.
sense receptors
This process, shown in the duck diagram on the test, combines the genetic material of a male and female parent.
fertilization
This is the term for the process by which a seed begins to sprout and grow into a new plant.
germination
In generation 0 of the guppy experiment, no predators were present. This is significant because it shows what the population looked like before this factor changed the traits of the population.
predation (or predators)
A scientist wants to test whether water is needed for photosynthesis. She grows two identical plants in the same amount of light but only waters one. This type of plant that receives no water is called this in the experiment.
the control (or the plant without water)
When a mutation changes one amino acid in a protein, it affects this aspect of the protein, which determines how well the protein can do its job.
the shape (or structure) of the protein
According to the data, rising temperatures in Antarctica are melting ice sheets, which destroys the habitat of krill. This is an example of how climate change can disrupt this.
food web (or an ecosystem)
This is the green pigment inside plant cells that captures light energy and makes photosynthesis possible.
chlorophyll
In the cholesterol protein example, the mutant protein removes cholesterol more efficiently because a mutation changed one amino acid, resulting in a different version of this.
protein shape
If krill disappeared from the Antarctic food web shown on the test, penguins would decline because this animal that penguins eat would also have less food.
fish (or squid)
Plants use water, carbon dioxide, and sunlight to make this sugar, which they use as food for energy and growth.
glucose
