molecule, species, cell, population, tissues, organism, biosphere, organs,
organ system.
Answer:
Atoms, molecules, cells, tissues, organs, organ system, organism,
species, population, community, ecosystem, biosphere
Question 2:
Describe an ionic bond and give an example.
Answer:
Electrons being transferred between any atoms. Ex. NaCl
Question 3:
Describe a covalent bond and give an exmaple.
Answer:
Electrons being shared between two or more atoms. Ex. CO2
Question 4:
Describe a nonpolar bond and give an example.
Answer:
Electrons that are shared equally between bonds.
,Question 5:
Describe a polar bond and give an example.
Answer:
Electrons that are shared unequally between bonds. Ex. H2O
Question 6:
Describe a hydrogen bond and give an example.
Answer:
Bonds between a slightly positive hydrogen and a nearby slightly
negative oxygen or nitrogen. Ex. H2O-H2O
Question 7:
The structure in a cell that contains the chromosomes. It has a membrane
around it and is where RNA is made from the DNA in the chromosomes.
Answer:
Nucleus

most eukaryotic cells, involved in secretion and intracellular transport.
Answer:
Golgi Apparatus
Question 13:
Membrane-enclosed organelles that contain an array of enzymes capable
of breaking down all types of biological polymers.
Answer:
Lysosomes
