Behavioral adaptation

Structural adaptation

Physiological adaptation

Genetic drift

It allows the animal to grow a stronger limb in its place

It provides a distraction to a predator, allowing the animal to escape

It reduces the metabolic cost of maintaining a large body during food shortages

It is a way to remove parasites that have attached to the extremity

Detect vibrations in the water (part of the lateral line system)

Pump water over the gills even when the fish is stationary

Store extra oxygen for when the fish is in hypoxic water

Regulate the amount of salt entering the body

A structural adaptation involving leaf size

A behavioral/temporal adaptation to maximize survival in ephemeral conditions

A physiological adaptation to high salt concentrations

A form of mimicry to avoid being eaten

It doubles

It quadruples ($4\times$)

It increases by eight times ($8\times$)

It stays the same

It doubles

It triples

It quadruples ($4\times$)

It increases by eight times ($8\times$)

To store a large volume of air

To provide a massive surface area for rapid gas exchange

To make the lungs stronger

To prevent the lungs from collapsing

Hearing distant sounds

Thermoregulation (cooling)

Communication

Protecting the eyes

Small animals have a high $SA:V$ and cannot maintain body temperature without high energy input

Large animals have a high $SA:V$ and lose heat too slowly

Small animals have a low $SA:V$ and gain heat too slowly

Large animals are too heavy to migrate

It decreases the surface area for oxygen binding

It increases the surface area to volume ratio for faster gas exchange

It increases the volume of the cell so it can carry more hemoglobin

It allows the cell to divide more easily

$16\text{ cm}^3$

$64\text{ cm}^3$

$128\text{ cm}^3$

$32\text{ cm}^3$

Cells differentiate into specific shapes (like neurons with long axons) to optimize their $SA:V$ ratio for their specific function.

Cells differentiate to decrease their $SA:V$ ratio so they can store more specialized organelles.

Cell differentiation occurs only when a cell reaches its maximum $SA:V$ limit.

Differentiation allows cells to bypass the $SA:V$ ratio by using active transport for everything.

Its high $SA:V$ ratio ensures that no cell is far from the surface, allowing $O_2$ to diffuse directly to all tissues.

Its low $SA:V$ ratio prevents it from losing too much oxygen to the surrounding water.

Its shape increases the volume of its digestive tract to compensate for the lack of oxygen.

Its flat shape is an adaptation for movement, and has no relation to its respiratory needs.

The highly branched network of capillaries in the circulatory system.

The broad, flat leaves of a rainforest tree.

The thick, insulating layer of blubber in a seal.

The large, hollow bones of a bird.

To increase its chances of survival

To make its habitat look better

Because it is bored

To become a different species

A short, powerful beak

A wide, flat beak

A long, thin beak

A hooked, sharp beak

A dry, sunny desert

A windy mountain peak

A shady, moist rainforest floor

The frozen Arctic tundra

To help them hear better in the wind

To minimize the surface area and reduce heat loss

To make them faster when running from predators

Because they do not need them

The eyes of a rabbit being located on the sides of its head

The forward-facing eyes of an owl for depth perception

The hard shell of a tortoise for protection

The bitter taste of a monarch butterfly

Protecting the seed from being eaten

Allowing the seed to float on water

Dispersal by sticking to the fur of animals

Allowing the seed to bury itself in the soil

A hot, tropical climate

A dry, desert climate

A very cold, polar climate

A temperate, grassland climate

A purely structural adaptation with no behavioral component.

A combination of structural (hydrophilic bumps) and behavioral (tilting) adaptations to a water-scarce habitat.

A physiological adaptation to change the chemistry of the air.

A defensive adaptation to look like a stone.

It makes them invisible to seals when they are swimming.

It helps to absorb and retain heat from the sun that penetrates the fur.

It is a vestigial trait from an ancestor that lived in the forest.

It protects them from the reflection of the snow.

The ability to see in the dark using a tapetum lucidum.

The sense of the relative position of one's own parts of the body, crucial for navigating complex 3D branch environments.

The ability to digest cellulose from tree bark.

The production of loud vocalizations to claim territory in dense foliage.

Individuals stop dying

All variation disappears

The population is adapted to the environment

Mutations stop occurring

A stable environment

A very slow change in temperature

A rapid change in the environment

Plentiful food and no predators

Desert

Grassland

Water

Forest

A group of the same species

A community of organisms interacting with their physical environment

A single animal

A type of weather

All mutations are harmful to the organism.

Mutations occur in response to a need in the environment.

Mutations are random changes in the genetic sequence.

Mutations only happen in animal species, not plants.

The species will become dormant until the environment changes back.

The species will go extinct.

The species will stop reproducing to save energy.

The species will choose to mutate into a more suitable form.

Gene flow

Genetic drift

Mutation

Sexual recombination

It is the total number of genes in an organism's genome

It is the difference between the fitness of the theoretical optimal genotype and the average fitness of the population

It is the maximum weight an organism can carry to survive

It is the amount of DNA transferred during reproduction

Species live in a circular habitat and can all interbreed freely

Neighboring populations can interbreed, but the two 'ends' of the chain cannot when they meet

A species has evolved a circular pattern on its skin to confuse predators

Evolution occurs in cycles of 100 years
