Half-life Problems & Microscope Math
What's more precise radioactive dating or relative dating?
Radioactive
What is morphology?
A physical structural trait.
What is carrying capacity?
The maximum number of a specie an environment can support.
What's a structural adaptation?
Involve a body's organism. Example: Wings of birds. Also includes warning coloration, mimicry, cryptic coloration.
What's mimicry?
When a organism replicates other animals or plants, this leads to higher fitness.
Based on relative dating what makes a fossil older than another.
What's the definition of a common ancestor?
Not a single individual or a link in a chain but reps a population of individuals from which the fossil animal of interest descended with modification.
What is the commensal relationship?
An association between two organism in which one benefits and the other neither benefits or is harmed.
What is behavioral adaptions?
Mating & parental behavior.
Ex. Vocal mimicry
What's the difference between biotic and abiotic?
Biotic is living organism and abiotic is non-living.
How do calculate FOV?
(Mag 1) x (diameter 1) = (Mag. 2) x (diameter 2)
What is a derived character?
A common trait between all members of a clade
What is Phyletic Gradualism?
Evolution that happens over time, in between species/steps of different species.
On a graph it's a straight line going up.
Note: What we normally think about when thinking about evolution
Who is the father of Taxonomy?
Carl Linnaeus
What is causation?
When one variable causes a change in another
What is the half-life of Carbon-14?
5,730 years
What is segmentation?
the division of an animal's body into repeating sections.
What's punctuated equilibrium?
Evolution that happens through steps. Two different spices that come from the same ancestor.
What's physiological adaptation?
Related to biochemistry & interactions w/ in body
Ex poison from snakes
What's the spatial scale of the Great Human Migration?
82% of the globe
If the FOV is 4.5mm and the specimen takes up 1/4 of the view? How large is the specimen.
1.12mm
Give an example of human skull evolution overtime
1. cranium capacity increasing overtime
2. Jaw size
What type of relationship is it called when one animal benefits and the other is harmed?
Parasitic
List the taxonomic categories in order.
Hint: Remember the acronym
What's the number of cell divisions?
Mitosis has one and makes 2 daughter cells
Meiosis has 2 and makes 4 daughter cells
