What do organs make up? Name one example (100 pts each).
Organs make up organ systems like the Digestive System, Respiratory System, Cardiovascular System,...

If bricks make up walls, walls make up rooms, rooms make up wings, and wings make up buildings, then what are cells equivalent to in this example?
BRICKS! Cells are the basic building block of organisms, like bricks are the building blocks of buildings. This is the second part of Cell Theory.

What does "-Stasis" mean as a suffix?
"-Stasis" = Staying in Place
200
Food can be used for __________ or __________. (100 pts each)
Energy or Growth
300
If a hypothesis is ONE POSSIBLE answer to a scientific question, then what is a conclusion?
the BEST POSSIBLE answer the scientific question based on the evidence obtained during experimentation
300
What is qualitative data?
Observations! - does not include numbers or amounts
300
What is an example of a living thing that does not have all of the characteristics of life?
Someone who is infertile, someone in a coma, viruses could be argued...
300
What is another name for macromolecule?
Polymer!
300
Where do new cells come from?
Other Cells! This is the 3rd point of Cell Theory. All cells come from pre-existing cells through cell division and the passing of genetic material from parent to offspring.
300
Name 3 examples of internal conditions maintained through negative feedback. (100 pts for each)
Heart Rate, Blood Pressure, Blood Glucose, Body Temperature, Blood pH, water retention,...
300
Metabolism is the process of getting energy from the __________ obtained during digestion.
Monomers!
400
Where does the Data Analysis of the scientific method go in a science article or lab report?
In the Discussion!
400
How does the reasoning help a CER argument?
The reasoning explains everything!! The reasoning describes HOW the evidence supports the claim, to convince the audience that it is true.
400
Name two types of single-celled organisms. (200 pts each)
Bacteria, Archaebacteria, some protists like Amoeba, some fungi
400
Polymers and monomers are examples of ______________.
Molecules!
400
What is the scientific name for cell division used to make new body cells?
*This question is not covered on the test.
Mitosis!
400
What kind of feedback does this graph represent AND what is one thing controlled by that type of feedback?
Positive Feedback
(Breast Milk production, platelets clotting, uterine contractions...)
400
__________________ is used for growth because it is the process of putting monomers back together to make new macromolecules.
Biosynthesis
500
Why are scientific articles so credible?
They are put through an intense peer-review process before being published, meaning they are read and analyzed by other experts in the field for accuracy and reasoning. Usually the authors need to make edits and run more experiments after review. This process can take years.
500
What is one way to improve your reasoning?
Include scientific backgroun information or write a counter argument!
500
How many domains of life are there?
3
500
Name 1 type of macromolecule and the monomers that make them up.
* This question is not covered on the test. (It will be on the next test :))
Carbs - Sugars
Proteins - Amino Acids
Lipids - Fatty Acids & Glycerol
Nucleic Acids - Nucleotides

What is the name of the scientist that observed a piece of cork in a microscope, noticed box-like structures, and called them "cells"?
Robert Hooke

Please explain why maintaining homeostasis is a Characteristic of Life.
Maintaining homeostasis is needed for survival. If homeostasis is not maintained, the organism is at risk for serious injury or even death. Therefore, living things need to maintain their internal conditions, making homeostasis a characteristic of life.

Why would our bodies want to break down macromolecules in digestion just to build them back up again in biosynthesis?
The macromolecules we take in through out food might not be the right kind or in the right form that we need to build the structures of our bodies. So, we reduce the macromolecules to the monomers, reuse the monomers for new macromolecules, essentially recycling them for our own use.
