Nature of Science
What is a scientists favorite type of dog?
A lab (just kidding its Hucky)
The most basic unit of matter
an atom
What is an example of something found in a eukaryote cell but not a prokaryote cell?
Many options - mitochondria, nucleus, ER, Golgi etc
What is the difference between passive and active transport
passive requires no energy, active requires energy input
What organelle is integral to cellular divison
the centrioles
What is a constant and why are they necessary to an experiment
Constants make experiments more reliable because they limit the outside factors that might impact the results
What organelle is involved in synthesizing lipids
Smooth ER
A red blood cell is placed in a solution of distilled water, what will happen to the cell? What type of solution is this?
It will burst because the solution is hypotonic
List and describe the steps of mitosis
Prophase, Metaphase, Anaphase, Telophase, Cytokinesis
When designing an experiment, scientists will test a relationship between a "cause" and an "effect." The "effect" is known as the
what is the dependent variable
When placed in water, oil does not dissolve or mix in, this is because oil is _______ and _______.
hydrophobic and nonpolar
What are the three parts of the cell theory?
All living things are made of cell(s)
Cells are the basic unit of life
Cells come from other cells
What type of transport is used when a white blood cell engulfs a bacteria in your body?
Active transport, endocytosis, phagocytosis
List the steps of the Cell Cycle
Interphase: G1, S, G2, Mitosis
Differentiate between precise and accurate
Precise is how close together the data is, accurate is how close to the actual recording the data is
Animals store most of their excess energy reserves as ________ because...
fat, they store twice as much energy per gram
What organelles are involved in making proteins
Nucleus, Ribosome, ER, Golgi
What is an isotonic solution?
A solution where the solute concentration is equal to that inside the cell
What is a stem cell? Why is it unique
Stem cells are undifferentiated types of cells that can become anything
Differentiate between qualitative and quantitative data
List the monomers and polymers of each macromolecule
Carbohydrates - monosacharrides, polysaccharides
Proteins - amino acids, polypeptides (proteins
Lipids - no real monomers/polymers but made of fatty acids and glycerol
Nucleic Acids - nucleotides and DNA/RNA
You find a cell that has a cell wall, a chloroplast and a central vacuole, what type of cell is this?
Eukaryote plant cell
Give an example of a feedback mechanism and describe whether it is positive or negative
Different options - hormones = positive, temperature regulation = negative
Why is it important for multicellular organisms to go through mitosis
Growth and repair of the cells
