All living things have _____, which are the basic, foundational unit of all living things. Letter C in our Characteristics of Life diagram.
What are cells?
These are the four macromolecules all animals need to survive.
What are carbohydrates, proteins, fats/lipids, and nucleic acids?
The specific role a species has within the ecosystem and how it obtains resources it needs.
What is an ecological niche or niche?
The process by which organisms that are most suited to their environment survive and reproduce most successfully.
What is natural selection?
The study of the living world is known as this.
What is biology?
Animals _______ & evolve in order to change and survive better in their environment. Ex. chameleons changing color to camouflage or blend in.
What is adapt?
What is ATP?
T or F: Two or more species can not occupy the same niche (for very long).
Natural selection is also known as this. EXTRA CREDIT on the test.
What is "survival of the fittest"?
This type of observation involves the characteristics, traits, and behaviors of subjects rather than numerical, quantitative measurements. Ex. color
What is a qualitative observation?
Animals with razor sharp canines and pointed teeth are more likely to be this kind of animal.
What is a carnivore?
An enzyme is a catalyst, helping to speed up chemical reactions in the body, and allowing these reactions to happen at a normal rate. Enzymes belong to this macromolecule (or biomolecule).
What is a protein?
Which of the following statements best describes resource partitioning?
A. Varying prey species maintain biodiversity.
B. Coevolution between two species means they can always share the same niche.
C. Similar species can coexist because of slight differences in each one’s niche.
C. Similar species can coexist because of slight differences in each one’s niche.
Heritable characteristics that increase an organism's ability to survive and reproduce in an environment. Letter A in our Characteristics of Life diagram.
What is an adaptation?
This is approximately the amount of energy left over from one trophic level to the next (expressed as a percentage).
What is 10%?
Scenario: A group of biologists discover a skull in the African savanna. Upon looking at its dentition (tooth anatomy), they find the animals teeth are wide and flat. What kind of animal does this likely describe?
What is an herbivore?
What is 2H2 and O2
Multiple species, which share a similar niche, can coexist in the same habitat due to sharing of scarce resources, aka this process.
What is resource partitioning?
A group of ecosystems that share similar climates and typical organisms. Ex. tundra, rainforest, grassland
What is a biome?
DOUBLE JEOPARDY (+400 Points): A natural network of interconnected feeding relationships (who eats whom) that shows how energy and nutrients move through an ecosystem.
What is a food web?
The process by which organisms keep their internal conditions relatively stable
What is homeostasis?
This process occurs when a protein or nucleic acid loses its 3D structure or "unfolds". Ex. frying an egg (egg white turns from clear to solid white)
What is denaturation or denaturing?
When two or more species have overlapping niches, this may occur.
What is competition?
Also acceptable: one species may outcompete the other(s)
Tusklessness in elephants is an __________ trait (something elephants are born with).
What is inherited?
Different versions of a gene.
What is an allele?
