Topic A
This is the most basic unit of life.
What is a cell?
These two subatomic particles are found inside an atom's nucleus.
What are protons and neutrons?
This principle of biology states that all cells come from pre-existing cells.
What is cell theory?
This type of energy is stored, such as the energy found in a glucose molecule.
What is potential energy?
This is the level of organization that includes both living and nonliving components of an area.
What is an ecosystem?
This is the process of a living thing maintaining a stable internal environment, like sweating when you're hot.
What is homeostasis?
A substance with a pH of 4 is considered to be this.
What is acidic?
This type of cell has a nucleus, is mostly multicellular, and is typically larger in size.
What is a eukaryote?
The Second Law of Thermodynamics states that all energy transfers are inefficient because some energy is always lost to this.
What is heat?
Found in both plants and animals, this organelle uses cellular respiration to extract energy.
What is the mitochondria?
The process where one parent produces offspring that are genetically identical to itself.
What is asexual reproduction?
This type of element, like iron or zinc, is required in small amounts for living systems.
What is a trace element?
This is the structure that encloses all cells and regulates what enters and leaves.
What is the cell membrane?
This is the main source of usable energy that powers all cell activities.
What is ATP?
This type of organism, like a plant, extracts energy from the nonliving environment.
What is an autotroph?
This is the most specific or exclusive level of the taxonomic hierarchy.
What is a species?
The monomer of the organic molecule carbohydrates.
What are monosaccharides?
A plant cell has this rigid outer layer for support and protection, which an animal cell lacks.
What is a cell wall?
This molecule, represented as C₆H₁₂O₆ is a reactant in cellular respiration.
What is glucose?
This is the time it takes for half of a sample of a radioactive substance to decay.
What is a half-life?
This is the kingdom often referred to as the "catch all" or "junk drawer" because it includes a diverse group of organisms that do not fit in the other kingdoms.
What is the kingdom Protista?
A chain of these subunits forms a protein, which is also called a polypeptide.
What is amino acids?
The synthesis of lipids is the primary function of this organelle.
What is the smooth endoplasmic reticulum?
These two molecules, produced by cellular respiration, are the primary reactants for photosynthesis.
What is water and carbon dioxide?
This "partially charged" molecule is restored to ATP by extracting energy from the environment, making it a critical part of the cell's energy cycle.
What is ADP?
