Scientific Method
What is the first step of the scientific method?
Asking a question or stating the problem
What are the basic units of life?
Cells
What is the most important property of water that makes it essential for life?
Water's ability to dissolve many substances (universal solvent)
Which biomolecule is primarily used for energy by living organisms?
Carbohydrates.
What is a hypothesis?
An educated guess.
All living things grow and develop. What process allows organisms to grow by increasing cell size or number?
Cell division (mitosis or meiosis) or cellular growth
What does it mean that water is a "universal solvent"?
It can dissolve a wide range of substances
What is the building block of proteins?
What do we call the information we gather during an experiement?
Data
What is the term for organisms that are made up of only one cell?
Unicellular organisms
What property of water allows it to travel up plant stems (capillary action)?
Cohesion & Adhesion
What are lipids commonly used for in living organisms?
Long-term energy storage, insulation and making cell membranes
Why is it important to have a control group in an experiement?
It serves as a baseline for comparison and helps eliminate other factors
How do living organisms respond to stimuli in their environment?
They have receptors or sensory organs that detect changes and cause responses (like moving toward light or away from heat).
What does it mean to say water has a high specific heat?
It takes a lot of energy to change the temperature (due to the hydrogen bonding)
What is the monomer (building block) of carbohydrates?
Monosaccharides (like glucose)
What is the difference between an independent variable and a dependent variable?
The independent variable is what you change; the dependent variable is what you measure.
What is metabolism, and why is it important for living organisms?
Metabolism is the set of chemical reactions that occur to maintain life, including energy production, growth, and repair.
What is surface tension, and how is it related to water?
Surface tension is the result of water molecules sticking together at the surface, creating a "film" on the surface of the water.
Nucleic acids carry genetic information. What are the two types of nucleic acids?
DNA & RNA
