Bonding
Bond formed between atoms of different charges
What is an ionic bond?
Bonding that allows for water to have special properties
What is hydrogen bonding?
Monomers of nucleic acids
What are nucleotides?
Organelle responsible for producing proteins
What is a ribosome?
Theory is based on two concepts: 1. Every living organism is composed of one or more cells. 2. All cells living today came from a preexisting cell
What is cell theory?
Bonds formed when atoms bond and share electrons unequally
What is a polar covalent bond?
Oils can't dissolve in water because of this
What is oils are nonpolar and water is polar. These unlike charges make it so they cannot mix
This macromolecule is used for long-term energy storage
What are lipids?
Organelle that extracts energy from food molecules, releasing carbon dioxide and water
What is the mitochondria?
Scientist who discovered cells
Who is Robert Hooke?
This is the number of bonds Al can form
What is three?
Ice is less dense than water. Why does this help living organisms?
What is ice will freeze at the top of a lake and insulate it, keeping the organisms alive underneath?
Reason why proteins have different functions
What is specific order of proteins? (will also accept folding for half points)
Three basic components of cytoskeleton
What are microtubules, intermediate filaments, and microfilaments?
Consists of an interdependent group of genetically identical cells that developed from a single cell and whose cells are incapable of living independently.
What is a multicellular organism?
This is the valence of Ne
What is zero?
Property when hydrogen bonds between water molecules generate an attractive force and stick together
What is cohesion?
Clusters of covalently-bonded atoms that have distinctive chemical and physical properties
What are functional groups?
Organelle that contains enzymes that break down macromolecules, releasing the subunits into the cytoplasm for recycling or waste removal
What is a lysosome?
Type of cell that has no nucleus
What are prokaryotes?
Will bonding between 1 nitrogen and 2 hydrogen satisfy the octets of each atom?
What is no?
Occurs when water molecules are heated, they become energetic enough to break their hydrogen bonds and escape as water vapor in a process
What is evaporation?
Only macromolecule with a functional monomer
What are carbohydrates?
Organelle that directs proteins and lipids produced by the ER to their final destination, either inside or outside the cell, through the addition of specific chemical groups
What is the Golgi Apparatus?
Correct order of the biological hierarchy
What is cell-tissue-organ-organ system-individual
