What is the first thing you should do before setting foot inside a lab?

Read the instructions.

100

Typically formatted in an if / then statement. 

The hypothesis.

100

Who is considered the Father of Evolution?

Charles Darwin

100

This is often referred to as the "driving force" of evolution. 

Natural Selection. 

100

Name two pieces of evidence for evolution. 

1.Fossils

2.Geographical Distribution

3.Embryology

4.Comparative Anatomy

5.Molecular and Genetic

200

If an accident occurs inside the lab, what is one thing you should always do?

Inform the teacher.

200

These are the things that remain the same throughout an experiment. 

Constants.

200

What does the theory of evolution state?

All life on Earth has descended from a common ancestor.

200

Name two of the four principles of natural selection. 

Genetic Variation, Overproduction of Offspring, Adaptation to the Environment, Descent with Modification

200

What are some examples of vestigial structures?

The tail bone in humans, ostrich wings, human appendix and wisdom teeth, whale and snake pelvis/hind legs

300

If you get a chemical inside you eye during a lab, how long should you (at minimal) rinse your eye at the station?

15 minutes. 

300
This is used as a standard comparison for your experiment--"how you know what you are changing actually matters". 

Control.

300

What is natural selection? 

Organisms that are better adapted to the environment are more likely to survive and reproduce

300

What does adaptation to the environment mean--explain or give an example. 

Organisms born with helpful adaptations will more likely survive and reproduce. 

300

Which evidence for evolution is also known as "Biochemical Evidence"

Genetic/Molecular

400

Name three different types of Personal Protective Equipment (PPE) that you might use in the lab.

Gloves, Goggles, Apron / Lab Coat, Closed Toed Shoes

400

What are the three types of graphs typically used to broadcast data?

Bar, Line, Circle or Pie. 

400

Explain how evolution occurs. 

Occurs over time, through natural selection, is a genetic process. 

400

How does overproduction of offspring change as you get to more complex organisms? For example, what is the difference between a clutch of spider eggs / spawn of fish eggs vs a litter of puppies or a bear cub litter?

As the organisms get more advance, you see less offspring produces, due to more energy being put into making the offspring. You also see factors like increased maternal care. 
400

What is the difference between analogous vs homologous structures?

Analogous structures have same function, but different evolutionary background. Homologous structures share the same evolutionary background, but not necessarily the same function. 

500

What is the proper procedure for extinguishing a fire (when handling the fire extinguisher)?

Pull the pin, aim at the base of the fire, and extinguish in a sweeping motion at the base. 

500
Two part question. If you were doing an experiment where time is the independent variable and plant growth was the dependent variable, which axis would time be plotted on, and what kind of graph would you use to showcase your data?

X axis, Line graph

500

Define adaptive radiation. (Hint: Think about what happened with Darwin's finches).

One species evolving into multiple different species that live in different ways based on their environment 

500

Why is genetic variation in a population so important? What would happen if there was no genetic variation. 

It is important to ensure the survivability of a species--with no variation, a species could be wiped out relatively easily. 

500

If C-14 has a half-life of 5,700 years, and we find a fossil with 25% of it's C-14 left un-decayed, what is the approximate age of this fossil?

11,400 years.
