Macromolecules I
100
This is composed of similar cells that function together as a unit.
What is a tissue?
100
This is composed of two or more different types of atoms bonded together.
What is a compound?
100
In this type of chemical bond, the partially positive hydrogen of one molecule of water bonds to one of the partially negative oxygens of another molecule of water. This bond is weak by itself, but in a drop of water, the collective force of these bonds is very strong.
What is a hydrogen bond.
100
Polarity of water results from this property of atoms.
What is electronegativity?
100
Chemical energy is stored here in biological molecules.
What is in the chemical bonds between the atoms?
200
This is a membrane-bound compartment inside of a eukaryotic cell.
What is an organelle?
200
This is a negatively charged particle that is outside the nucleus of an atom.
What is an electron
200
This type of molecule has a partial negative charge on one side of the molecule and a partial positive charge on the other side of the molecule.
What is a polar molecule?
200
This property of water allows water to stick to other water molecules, creating surface tension. Some insects can glide on the water surface because of this property. (not looking for polarity)
What is cohesion?
200
These are chemical groups bonded to hydrocarbons that participate in chemical reactions with other molecules and give the biological molecule its particular function.
What is a functional group?
300
These are all of the organisms on earth that are similar to each other, can interbreed, and can produce viable offspring.
What is a species
300
This is a positively charged particle that is inside the nucleus of an atom.
What is a proton?
300
The polarity of water results from this property of atoms, whereby some atoms have a higher affinity for electrons than others.
What is electronegativity?
300
This property of water causes water to stick to other charged molecules. This is useful during translocation of water through xylem vessels of plants because it sticks to the inside of these vessels. Without this property, we would not have plants as we know it today, and we probably would not exist like we do today. (not looking for polarity)
What is adhesion?
300
This is the term for a molecule composed of repeating units of similar molecules bonded together.
What is a polymer?
400
This consists of different populations that interact with each other and the physical (abiotic) environment with which those populations also interact.
What is an ecosystem?
400
These electrons are the electrons found at the highest energy level, usually farthest from the nucleus of an atom.
What are valence electrons?
400
Because of this physical property of water molecules, water can easily break apart molecules, like sodium chloride (NaCl) into ions, and keep them apart. (not looking for polarity)
What is solubility?
400
Water is a good temperature regulator because of this property, as it takes a large change in heat energy to change the temperature of water. Because of this, water temperature does not readily change.
What is high specific heat?
400
Biological macromolecule polymers are build by this type of chemical reaction.
What is a dehydration reaction?
500
This is a group of organisms that are similar to each other, can interbreed and produce viable offspring, and that live in the same geographical region.
What is a population?
500
Electrons are shared in this type of chemical bond.
What is a covalent bond?
500
In this type of bond, electrons are lost from one atom and gained by another atom, thus causing the atoms to have opposite charges,which in turn causes the atoms to bond to each other.
What is an ionic bond?
500
It takes a lot of heat energy input to change liquid water to water vapor. Because of this property, water is excellent at cooling systems, like human bodies and atmosphere, as the water absorbs heat to break hydrogen bonds holding the water molecules together.
What is high heat of vaporization? (or high heat of evaporation)
500
Molecules in this the category of carbohydrates contain only one sugar molecule.
What is a monosaccharide?
