Characteristics of Life
This ability, common to all living things, involves maintaining a stable internal environment
What is homeostasis?
The atomic number equals this number of particles in the nucleus (always)
What are protons
This is the monomer for carbohydrates
What are monosaccharides
This level of protein structure involves hydrogen bonding between backbone groups.
What is secondary structure?
In a neutral atom, the number of protons equals this number of particles
Electrons
Populations of organisms share this ability, which explains changes across generations.
What is evolution?
These atoms differ in their number of neutrons but share the same number of protons.
What are isotopes
These proteins prevent misfolding of other proteins.
This RNA type delivers amino acids to the ribosome.
What is tRNA (transfer RNA)
What is Valence Shell
The complete sum of DNA in an organism is called this.
What is the genome?
A bond where atoms share electrons.
What is a covalent bond?
This polysaccharide stores energy long-term in animals.
What is glycogen
The bond that links nucleotides in DNA and RNA.
What are phosphodiester bonds?
This term means "water-loving"
What is Hydrophilic
This kind of explanation assumes no differences exist between groups.
What is a null hypothesis?
Water is such a good solvent because it is this type of molecule.
What is polar?
This nucleotide is the main energy currency of the cell.
What is ATP
This is the primary function of Nucleic Acids
What is storing and expressing genetic information?
This property of water, caused by hydrogen bonding, explains why water molecules stick to each other and create surface tension.
What is cohesion?
This evolutionary innovation allowed life to spread to land
The outermost electron shell of an atom determines this property
What is chemical reactivity
This type of lipid has double bonds between carbons
What are unsaturated fatty acids?
A nucleotide consists of these three parts.
What are sugar, phosphate, and nitrogenous base?
Having a higher electronegativity means an atom will do this in a molecule.
What is pulling electrons towards its nucleus
