Unit 0
It the type of data that is categorical; can be described with words but not necessarily numbers
What is qualitative data?
They both separately concluded that living things evolve by adapting to their environments
Who are Wallace and Darwin?
They have very restricted tolerance ranges and can only occupy very particular niche spaces
What are specialists?
They are substances that cannot be broken down further or transformed chemically
What are elements?
It is a limiting factor where availability changes with population size
What is a density-dependent factor?
It's a conclusion drawn based on data and observations
What is an inference?
1- variety of traits
2- heritable traits
3- differential reproductive success
It's when both species benefit from the interaction
What is mutualism?
It's a component of an element, consisting of protons, neutrons, and electrons
What's an atom?
It's the group that does not receive the treatment and is used as a point of comparison
What is a control group?
It's the variable that is changed or manipulated by the researcher
What is the independent variable?
This describes that some traits may not have a clear survival advantage but are selected for if preferred by mates
What is sexual selection?
It describes when the growth rate slows down due to limiting factors, which set the population’s carrying capacity (K)
What is logistic growth?
It forms when a metal atom GIVES electrons to a nonmetal atom, forming a compound
What's an ionic bond?
This type of selection is when individuals with intermediate phenotypes are the most “fit”
What is stabilizing selection?
It's the type of graph you use to show a change over time; two numerical variables.
What is a line graph?
This type of selection is when individuals with both extreme phenotypes experience the highest fitness; those with intermediate phenotypes have the lowest
What is disruptive selection?
It's when in more stable environments, offspring are more likely to make it to adulthood, so parents tend to have relatively few babies and invest more into parental care
What is k-selected reproduction?
It's a charged atom formed by gaining or losing electrons
What's an ion?
It's an invertebrate phyla characterized by "spiky skin"
What is echinodermata?
This describes the why by proposing explanations for something you observe.
What is a hypothesis?
This is the only type of gene sharing that does not introduce new genetic material.
What is binary fission?
It's when organisms live in groups or cluster around limited resources
What is clumped distribution?
It's the unequal sharing of electrons
What is polarity?
They are structures that have the same function but came about from unrelated organism
What are analogous structures?
