MICR 130 - EXAM 1Questions and
Correct Answers
1) THE SCIENTIFIC METHOD
A) is a creative process used in science to learn about the natural world
B) is used to determine the absolute truth about any situation
C) involves an observation of the natural world and development of a question
D) involves making hypotheses, experiments and conclusions then, based on your results—another
hypothesis...
E) is based on presuming that everything that can be perceived can be understood based on belief as
does religion - Answer-A, C, D
2) WATER
A) has hydrogen bonding between water molecules that lead to cohesion and stability to temperature
change
B) has surface tension due to cohesion that small animals (insects) can move on
C) is non-polar like lipids
D) stabilizes temperature due to its high specific heat and so contributes to homeostasis in organisms
E) stabilizes temperature due to its high specific heat and so contributes as a large body of water in the 3
Gorges Dam project (China) to providing oranges to a region that can not usually grow them
, F) is produced in chemical reactions that join monosaccharides to make polysaccharides and amino acid
to make proteins (by splitting out H2O)
G) is split in the light dependent reaction of photosynthesis to produce oxygen (and H+ and electrons)
TRUE - Answer-A,B,D,E,F,G
3) CARBON atom with atomic number of 6 (and mass number of 12):
A) has 6 neutrons, 6 protons, 8 electrons
B) has 4 electrons in its outer shell
C) has a valence of 4
D) has 2 electrons, 2 protons, 2 electrons
E) bonds with another atom (usually Hydrogen) to form the basic unit of organic chemistry **
F) makes 4 bonds to fill its outer electron shell in different ways (single, double and triple bonds)—this
leads to the potential for diverse structures
G) is channeled into the biosphere through photosynthesis (true!)
H) bonds with hydrogen at every chance to make a saturated carbon (lipids can be saturated and-or
unsaturated) * - Answer-B,C,E,F,G,H
4) ELEMENTS
A) that are most common in living matter include CHO and N, P, S and K (OK—K not discussed but it is
considered a macronutrient)
B) are made of several types of atoms each
C) as atoms in water are bonded together by covalent bonds while the H2O molecules are bonded
together by Hydrogen bonds
D) as atoms with 1 electron in the outer shell would like to get rid of that electron and so participate in
hydrogen bonds
E) as atoms with 1 electron in the outer shell would like to get rid of that electron and so participate in
covalent bonds
F) as atoms with 1 electron in the outer shell would like to get rid of that electron and so participate in
ionic bonds - Answer-A,C,F
