BIOLOGY 152 EXAM 1 WITH CORRECT
ANSWERS 2025
attributes of life correct answers >> cellular organization,
metabolism, growth, response to stimuli, reproduction, heredity,
movement
biology correct answers >> The study of life
chemistry of life correct answers >> all living organisms are
composed of macromolecules: carbohydrates, proteins, lipids, and
nucleic acids
polymers correct answers >> large compound formed from
combinations of many monomers
macromolecules correct answers >> A very large organic
molecule composed of many smaller molecules, a type of polymer
carbohydrates correct answers >> store chemical energy.
most dissolve in water. sugars starches, cellulose
proteins correct answers >> facilitate specific chemical
reactions and are building materials for cells, regulatory, and
transport molecules. made of amino acids. 20 types of amino
acids
, lipids correct answers >> form part of the biological
membrane and store energy. turns into fat when stored for a long
time. do not dissolve in water. fats, oils, phospholipids, steroids,
and terpenes
nucleic acids correct answers >> store heredity information.
DNA and RNA
peptides correct answers >> short proteins
polypeptides correct answers >> long proteins, amino acids
DNA correct answers >> nitrogen bases A-G and T-C
RNA correct answers >> nitrogen bases A-G and U-C
prebiotic evolution correct answers >> all organisms on
earth are made up of the same building blocks: sugars, lipids,
amino acids, and nucleotides. no oxygen or ozone layer in the
primitive environment.
Miller Experiment correct answers >> -Stanley Miller, 1953,
simulated the primitive conditions of earth inside a simple glass
apparatus. He treated a mixture of water and gases with flashes
of artificial lightning. 5 amino acids were produced. This
experiment was repeated with different atmospheres and sources
of energy. As long as there was no oxygen present, the same 5
amino acids were produced.
-adenine can easily be formed from hydrogen cyanide: ATP
