Punnett Squares
In Mendelian genetics, this is represented by a capital letter.
What is a dominant allele?
The process by which species change over time.
What is evolution?
The geologic principle that states that in horizontal layers of sedimentary rock, each layer is older than the layer above it and younger than the layer below it.
What is the law of superposition?
What are:
Domain, Kingdom, Phylum, Class, Order, Family, Genus, Species
An environmental factor that causes a population to decrease in size.
What is a limiting factor?
In Mendelian Genetics, this is represented by a lowercase letter.
What is a recessive allele?
An inherited behavior or physical characteristic that helps an organism survive and reproduce in its environment.
What is adaptation?
Two environmental conditions that allow fossils to form.
What is:
Low oxygen
Under water
Sediment
The four characteristics used to classify organisms.
What are:
Energy source, Number of cells, Presence of nucleus, and Type of reproduction
The four levels of a food chain or energy pyramid.
What are: Producer, Primary consumer, Secondary consumer, tertiary consumer.
Solve the Punnett Square on the board.
(see board for correct answer)
The process by which organisms that are best adapted to their environment are most likely to survive and reproduce.
What is natural selection?
True or false: natural selection allows organisms to evolve dramatically over time.
What is:
True
The levels of classification that make up an organism's scientific name.
What are:
Genus and Species
Where producers get their energy.
What is the sun?
In a cross between two heterozygous parents, this percent of offspring will display the dominant trait.
What is 75%?
This scientist studied various organisms, including finches and tortoises, on the Galapagos Islands.
Who is Charles Darwin?
Difference in organisms' DNA that contributes to the process of evolution.
What is genetic variation?
Plants, animals, and fungi are in this domain.
What is eukarya?
Living things' energy ends up being used by these organisms when they die.
What are decomposers?
In a cross between two heterozygous parents, this percent of offspring will be homozygous recessive.
What is 25%?
The main reason the Galapagos finches had different sized beaks.
What is:
Natural selection causing the species to evolve different beak sizes due to different food sources on each island.
Structures that are similar in different species and that have been inherited from a common ancestor.
What are homologous structures?
A tiger is in the Kingdom Animalia, the Phylum Chordata, the Class Mammalia, the Order Carnivora, the Family Felidae, the Genus Panthera, and the Species tigris. This is the tiger's scientific name in binomial nomenclature.
What is Panthera tigris?
The level of an energy pyramid with the least available energy.
What is the tertiary consumer level?
