Biomolecules
100
This is the first step of the scientific method.
What is identify the problem/state observations?
100
The characteristic of life that relates to changing in size
What is growth?
100
The variable in an experiment that does NOT change--it remains constant.
What is the control variable?
100
This structure is found in all cells, and creates proteins.
What are ribosomes?
100
These macromolecules are responsible for instant energy!
What are carbohydrates?
200
This is the last step of the scientific method.
What is retest?
200
The characteristic of life that relates to DNA and RNA.
What is having genetic code?
200
You have two plants of the same species. One plant is kept in normal sunlight and one plant is kept covered, in the dark. You measure the plant growth every day at the same time. Describe the "amount of sunlight" in terms of a variable.
What is the independent variable?
200
This organelle is the powerhouse of the cell, responsible for producing energy in the form of ATP.
What is a mitochondrion/what are mitochondria?
200
These macromolecules store energy and are comprised of fatty acids.
What are lipids?
300
This part of the scientific method involves creating a procedure.
What is designing an experiment?
300
All living things are made up of these.
What are cells?
300
You have two plants of the same species. One plant is kept in normal sunlight and one plant is kept covered, in the dark. You measure the plant growth every day at the same time. Describe the "plant growth" in terms of a variable.
What is the dependent variable?
300
The group of organisms that includes ONLY bacteria (eubacteria, archaebacteria)
What are prokaryotes?
300
These macromolecules create our genetic material, including DNA and RNA.
What are nucleic acids?
400
In this part of the scientific method, you state the answer to your question and the results of your hypothesis.
What is the conclusion?
400
Living things change over time due to this phenomenon.
What is evolution?
400
You have two plants of the same species. One plant is kept in normal sunlight and one plant is kept covered, in the dark. You measure the plant growth every day at the same time. What is the control variable in this experiment?
What is the same type of plant? Same type of soil? Same amount of water?
400
This group of organisms has chloroplasts.
What are plants and algae?
400
The monomer of a protein.
What are amino acids?
500
This statement allows scientists to provide an answer to their question, problem or observations, in the form of an "if"..."then"...statement. It is an educated guess.
What is a hypothesis?
500
Living things have cells that can be modified into many forms, such as by stem cell modification, through this process.
What is differentiation?
500
Design your own experiment regarding the plant example, making sure to include an independent variable, dependent variable, control and hypothesis.
What is --answers vary--
500
This organelle is responsible for bearing ribosomes, and for producing proteins.
What is rough endoplasmic reticulum?
500
Proteins are largely made up of what elements?
What is carbon, hydrogen, oxygen, nitrogen?
