What are other names for biomolecules?
Organic molecule, living molecule, macromolecule, some of them are polymers
You use your senses to make ______, before you start the experiment

The factor of the experiment that is being tested (you can change it)
The factor of the experiment that is measured/calculated
The factor of the experiment that is not being tested, and is used for comparison
independent variable

Name 4 biomolecules that make up our body.
Protein, carbohydrate, fat/lipid, nucleic acid (DNA, RNA)
What chemical element is the backbone of all biomolecules on our planet?
Carbon, C
List all 7 steps of Scientific method
Question, observation, hypothesis, experiment with data collection and analysis, results with reasoning, conclusion, communication
Basic unit to measure mass
gram
In Biology, maintaining a stable internal environment is called
homeostasis
What are 2 examples of monosaccharides?
2 examples of disaccharides?
glucose, fructose
sucrose, lactose
True or False: Living things pass down an identical genetic code to their offspring. Explain.
False. Because usually mutations occur. If sexual reproduction occurs, then the offspring differ from their parents.
What is the origin of the word "Science" ?
It came from the Latin word "scientia" which meant knowledge.
Basic unit used to measure volume
liter
cm3
Major characteristics of living things are the following:
Ability to:
reproduce, grow and develop, interact, maintain homeostasis, metabolize, respond to stimuli, consist of cells
What 3 different types of proteins in our body do you know? What are their functions?
Hemoglobin - transportation of O2
Enzyme. - detoxification, digestion
Collagen - structure (bones, tendons, skin, muscles, ligaments)
Hormone - growth and development, metabolism, mood/feelings
True or False: All polymers are macromolecules, but not all macromolecules are polymers.
Explain, give examples
True: Polymers are made of monomers that can be repeated many times: carbohydrates, proteins, nucleis acids. Lipids are not polymers.
Macromolecules contain 1000s or more of atoms, but they are not made of similar or identical monomers. All 4 biomolecules fall to this category.
It is used to test the hypothesis
experiment
What is the formula for calculating the density?
What are its units in SI system?
Density = Mass/ Volume
g/cm3, g/mL
What does this represent:
cells -> tissues ->organs ->organ systems ->organism
Level of bio organization of living things
We need carbs for ....
fats for ...
proteins for....
nucleic acids for ....
quick energy
insulation, long-term energy
structure, repair, and last resort energy source
genetics
True or False? "Viruses are living things." Explain why you think so.
Partially False, Partially True. It is controversial.
Some scientists consider them living, some don't.
Although they lack the ability to maintain homeostasis, lack cellular organization and depend on a host for reproduction & development, they still respond to stimuli and can adapt to environmental changes.
