Module 1: Science of Life
This uses your five senses to gather factual information.
An observation
This determines the vast majority of characteristics in an atom.
The number of electrons (or protons)
This is the principal means by which oxygen is taken from the air.
Respiration
What are the 3 main ideas of cell theory?
1. all living things are composed of cells
2. cells are the basic unit of structure and function
3. all cells come from pre-existing cells
An organism is classified as a herbivore. Is it a heterotroph or an autotroph? Is it a producer, consumer, or decomposer?
Autotroph - it depends on other organisms for food
Consumer - it eats only plants
This is a logical interpretation of observations based on knowledge or experience.
An inference
18 electrons
This is the principal means by which oxygen is restored to the air.
Photosynthesis
A cell has a membrane-bounded nucleus and organelles. Is it categorized as a eukaryotic cell or a prokaryotic cell?
a eukaryotic cell
These are the basic building blocks of proteins.
Amino acids
This is a possible testable explanation for observations.
A hypothesis
How many of which atoms does the molecue C4H8O2 contain?
Carbon (4 atoms)
Hydrogen (8 atoms)
Oxygen (2 atoms)
Abiotic factors
This organelle contains its own DNA.
mitochondria
A substance measures 12 on the pH scale, is it acidic, neutral, or alkaline?
alkaline
This is a thoroughly tested and well-supported explanation of a natural phenomenon or a group of observations.
A scientific theory
The molecule C5H10O5 contains this many total atoms.
20 atoms
This level of ecological study includes all the other levels.
Ecosystem
This chemical process occurs in chloroplasts
Photosynthesis
What are the six criteria for life?
All life is composed of cells and cells are the most basic unit of structure and function for living things.
All living things: grow, require energy, maintain a stable internal environment by regulating chemical processes, respond to their environment, and contain hereditary information in their DNA.
This is a well-supported description of a natural relationship of principle, often using a mathematical equation.
A scientific law
Name and define two properties of water that allow life to thrive on Earth.
1. Universal Solvent - dissolves many substances
2. Cohesion - attracts other water molecules
3. Adhesion - attracts other polar substances
4. Density - ability to float as a solid
5. High heat capacity - ability to absorb large amounts of thermal energy before its temperature increases
A mouse eats nuts and seeds. What is its trophic level?
A mouse is a primary consumer or trophic level 2
What is the difference between active and passive transport? Give an example of each.
Passive transport is the transport of molecules without using energy while active transport requires the use of energy to move molecules.
Passive transport examples: diffusion, osmosis, and facilitated diffusion.
Active transport examples: endocytosis, exocytosis, and pumps
DNA stores information as a sequence of nucleotide bases. What are the three basic parts of a nucleotide?
A phosphate group, a sugar, and a base
