Identify the primary consumer.

grasshopper

Structures that have no apparent function and appear to be residual parts from a past ancestor.

vestigial structures

Name two pieces of evidence of evolution.

fossils, H-W calculations, comparing DNA/protein sequences, direct observation, homologous/analogous/vestigial structures

A gene has two alleles, B = brown, b = white. The frequency of white-haired goats is 25%. What is the frequency of heterozygous individuals?

0.5

Identify & describe the outgroup.

lamprey; most differences compared to the rest; distantly related to the rest of the organisms

The loss of genetic variation that occurs when a new population is established by a very small number of individuals from a larger population.

founder effect

A species population becomes separated by a geographic barrier, whereby reproductive isolation evolves producing two separate species.

allopatric speciation

Explain two density-dependent factors that limit population growth past carrying capacity.

competition, territoriality, disease, intrinsic factors

These organisms are low in number, but serve a key role in the environment. Without them, the ecosystem could collapse. Example: otters help maintain kelp forests

keystone species

Two organisms have similar traits because they live in similar environments, not because they have a recent common ancestor. What type of evolution is this?

convergent

List three abiotic factors that affect a fennic fox's survival and reproduction in the desert.

water, sunlight (shade), shelter, precipitation

Something is missing! What organism(s) should be drawn in around #5?

decomposers

Describe the relationship between species diversity and stability/resilience of a population

The higher the diversity, the more resistant/resilient the community is to change.

Use terms "positive" "negative" "neutral" to describe the effect of competition on each individual.

negative / negative (both are harmed)

These birds are closely related and eat similar foods. Each type of bird searches for food in different parts of the trees. What is this?

resource (niche) partitioning

Which scientist supported the hypothesis that acquired traits (like ability to play the trumpet) could be passed to offspring?

Jean Baptiste Lamarck

Describe one adaptation that prey have to help avoid getting eaten.

mimicry, camouflage, keen senses, speed, poison, toxins

List three biotic factors that affect a boa constrictor's survival and reproduction in the rainforest.

Food/competition/predators

Name an herbivore.

any organism that eats plants

A sharp reduction in the size of a population due to environmental events such as famines, earthquakes, floods, fires, disease, and droughts.

bottleneck effect

K-selected species typically follow a Type I growth curve. Name one K-selected species.

Few offspring, large body size, late maturity, parental care (humans, elephants, blue whale)

Two organisms have similar underlying structures because they share a recent common ancestor. What type of evolution is this?

divergent evolution

Describe one adaptation that predators have to help catch prey.

claws, camouflage, keen senses, teeth, speed, etc.

The change in frequency of an existing gene variant in the population from one generation to another due to random chance; effects more severe in small populations.

genetic drift

The movement of genes into or out of a population.

gene flow

Divergent evolution leads to organisms having ___ structures.

homologous

Convergent evolution leads to organisms having ____ structures.

analagous

What type of growth model is this?

logistic

A gene has two alleles, B = brown, b = white. The frequency of white-haired goats is 25%. What is the frequency of the b allele?

0.5

What is commensalism?

A type of symbiotic relationship where one individual benefits and the other is neither harmed nor helped (unaffected).
