ANSWERS CORRECT VERIFIED BEST RATED A+ FOR PASS
Amino group - CORRECT ANSWERS -N2H, found in all amino acids
carboxyl group - CORRECT ANSWERS -COOH Found in all amino acids
R group - CORRECT ANSWERS A unique function group that is different for each amino
acid
Nucleic acids - CORRECT ANSWERS are necessary information for producing proteins,
they are built using nucleotides, which are composed of a 5-carbon sugar, a phosphate sugar, a
phosphate group, and a nitrogenous base. DNA is made up of four nucleotides; adenine,
guanine, cytosine and thymine, in RNA thymine is placed by uracil
Cell - CORRECT ANSWERS The most basic unit of life
Robert Hooke - CORRECT ANSWERS Inventor of the microscope
Antony van Leewenhock - CORRECT ANSWERS Pioneered new develops in the field of
microscopy
2 Types of Cells in the body - CORRECT ANSWERS Prokaryotic and Eukaryotic cells
Prokaryotic cells - CORRECT ANSWERS Bacteria, archaea, do not have a nucleus, DNA is
contained in the nucletoid, most often unicellular, asexual reproduction
Eukaryotic cells - CORRECT ANSWERS Have a nucleus, DNA is contained in the nucleus,
multicellular, can be either asexual or sexual, both cells types have cell walls, plasma
membranes, cytoplasm, organelles, flagella, and ribosomes that make proteins

Mitochondria - CORRECT ANSWERS Makes ATP within the cell
Vacuole - CORRECT ANSWERS Transfers materials within and out of the cell
Nucleus - CORRECT ANSWERS Holds the genetic information
Endoplasmic Reticulum - CORRECT ANSWERS translates mRNA into proteins
Ribosome - CORRECT ANSWERS Reads mRNA and creates an amino acid
Cell membrane - CORRECT ANSWERS Surrounds the cell and performs numerous
functions. It is composed of compounds called phospholipids and includes transmembrane
proteins which cross the entire membrane
Active transport - CORRECT ANSWERS Uses ATP to move a molecule against the
concentration gradient or to a import/export a bulky molecule
Passive transport - CORRECT ANSWERS Does not require energy. Allows molecules to
passively diffuse across the cell membrane
Osmosis - CORRECT ANSWERS Net flow of a solvent across a semipermiable membrane
in response to a concentration gradient
Tonicity - CORRECT ANSWERS Concentration of solutes in a cell, which affects the
chemiosmotic potential, or the water entering or exiting the cell to make the tonicity equal
across the membrane

ANSWERS CORRECT VERIFIED BEST RATED A+ FOR PASS
Isotonic enviroment - CORRECT ANSWERS The same concentration of solutes exists in
and out of the cell
Hypertonic enviroment - CORRECT ANSWERS The concentration of solutes is higher
outside the cell, so the cell will lose water
Hypotonic enviroment - CORRECT ANSWERS The concentration of solutes is higher
inside the cell, so the cell will gain water
Cyclic AMP - CORRECT ANSWERS Signaling molecules, such as when epinehphrine
binds to a cell
Neurotransmitters - CORRECT ANSWERS Signaling molecules, such as glycine,
aspartate, acetylocholine, dopamine, serotonin, and melatonin
Local or direct signaling - CORRECT ANSWERS When two cells that are either next to
each other of within a few cells from each other communicate
Hormones - CORRECT ANSWERS are used in long-range signaling
Enzyme - CORRECT ANSWERS Large protein that acts as a catalyst
DNA polymerase - CORRECT ANSWERS For copying DNA
Pyruvate kinase - CORRECT ANSWERS For glycosis
