Characteristics of Life
All living organisms are made up of one or more of these.
What are cells?
These simple cells lack a nucleus and membrane-bound organelles.
What are prokaryotic cells?
The difference between active and passive transport of materials across a cell membrane is that active requires this.
What is energy?
An educated guess is called this.
What is a hypothesis?
Plant cells have this rigid structure, but animal cells do not.
What is a cell wall?
Set of chemical reactions in organisms that allow them to convert food into energy and get rid of wastes.
What is metabolism?
This organelle is considered the powerhouse of the cell.
What is the mitochondrion?
A cell will do this when put in a solution of salt water.
What is shrink?
A beekeeper wants to know how temperature within the hive affects the amount of honey produced. The dependent variable in this example is this.
What is the amount of honey?
The lack of this force in space makes it impossible to burp there.
What is gravity?
Someone unexpectedly bangs on the door, and you jump. The stimulus in this example is this.
What is the bang on the door?
Deoxyribonucleic Acid is found in this organelle.
What is the nucleus?
Two important products of photosynthesis.
What are glucose and oxygen?
An example of quantitative data is this.
What is any numbered measurement? such as length (5mm), mass (10g), temperature (degrees C or F), etc.
Okasaki has cells that contain a nucleus and membrane-bound organelles. These cells can also be called this.
What are eukaryotic cells?
The small bud produced by asexual reproduction in yeast cells is called this.
What is a bleb?
The hydrophilic heads that make up the phospholipid bilayer of the cell membrane have this relationship with water (love or hate).
This product of cellular respiration in our cells is taken up through the stomata of plant leaves for the process of photosynthesis.
What is carbon dioxide?
The variable that you change in an experiment, to see what effect it will have.
What is the independent variable?
The most beautiful and pristine mushroom to ever grace the planet.
Who is Toad?
A human's ability to maintain an internal temperature of 98.6 degrees F is an example of this.
What is Homeostasis?
What is cilia?
The movement of water across a cell membrane is called this.
What is osmosis?
Mythbusters wanted to know if elephants are afraid of mice. They first tested their hypothesis by moving a large ball of elephant dung to reveal a live mouse inside. The elephants were afraid. To eliminate the possibility that movement alone caused their fright, the mythbusters did this.
What is moved a large ball of elephant dung without a live mouse inside?
What is approximately 38 minutes?
