2026 SOLVED QUESTIONS ACCURATE
◉ covalent bonds. Answer: Bonds created by sharing electrons with
other atoms by merging valence orbitals
◉ nonpolar covalent bonds. Answer: even/ equal, and are
hydrophobic meaning they do not disolve in water
◉ polar covalent bonds. Answer: not even/ not equal, and are
hydrophilic meaning they disolve in water
◉ A pH of 7 is _______. Answer: neutral
◉ a pH more than 7 is. Answer: basic
◉ a pH less than 7 is. Answer: acidic
◉ organic chemistry refers to.... Answer: chemistry involving carbon
(usually carbon-carbon bonds)
,◉ Carbon has 6 protons; therefore, it typically has 6 electrons (4
valence). How many bonds can it form?. Answer: 4, it needs 4 more
to be a full shell (8)
◉ polymerization?. Answer: chemical process that creates polymers
by linking many small molecules, called monomers, into large chains
or three-dimensional networks. typically dehydration reactions
◉ Hydrolis. Answer: a chemical reaction that involves a water
molecule breaking a larger molecule into two smaller fragments
◉ 4 major families of biomolecules. Answer: carbohydrates,
protiens, nucleic acids, lipids
◉ Proteins are formed by bonding __ together to for a large chain..
Answer: amino acids
◉ You are testing a new plant fertilizer. You believe that this
fertilizer will help plants to grow more quickly than the fertilizer you
have been using. You administer your fertilizer to 40 plants, and give
the other 40 the regular fertilizer. The plants that were given the
new fertilizer grew 10% taller than the other group during your 3
week experiment.
In this example, the change in growth due to the administration of
the fertilizer is known as the __.
, dependent variable
independent variable
control group
placebo. Answer: dependent variable
◉ Proteins are formed by bonding __ together to for a large chain.
a. amino acids
b. monosaccharides
c. nucleic acids
d. cholesterol
e. lipids. Answer: amino acids
◉ Many macromolecules in the cell are formed by binding together
many small building blocks to form the final large molecules.
Molecules built in this way are referred to as __.
a. salts
b. organic
c. ligands
d. polymers
e. hydrophobic. Answer: polymers
