Cell Organelles
What part of a cell is closely stacked, flattened sacs (plants only)?
vacuole
Is the verb in the following sentence transitive or intransitive:
Have you washed your hands?
transitive
What is the equation to find speed?
Speed = equals distance divided by time
What is an example of a lipid?
waxes, oils, sterols, cholesterol, fat-soluble vitamins, monoglycerides, diglycerides, triglycerides (fats), and phospholipids.
Fatty acids (including fats) are a subgroup of lipids, hence, it will be inaccurate to consider the terms synonymous.
What is the difference between kinetic and potential energy?
Kinetic - energy of motion
Potential – stored energy (energy of position, location)
What part of a cell stores material within the cell?
Mitochondrion
What is the verb in the following sentence? Is it an action verb or a linking verb?
A ten-item quiz seems impossibly long after a night of no studying.
- seems
- linking
What is the equation to find velocity?
velocity = change in displacement over time
What macromolecule is the main source of energy for living things?
carbohydrates
State the Law of Conservation of Matter and Energy.
Matter (and energy) is neither created nor destroyed. (energy can be converted from one form to another)
Cell organelle which digest excess or worn-out cell parts, food particles, and invading viruses or bacteria.
lysosomes
Identify the prepositional phrase. Is it adjectival or adverbial?
- of grace and delicacy
- adverbial
What is the equation to find acceleration?
acceleration = final velocity minus initial velocity over time
What is the monomer for the polymer carbohydrates?
monosaccharides
What is the difference between a homogeneous and heterogeneous mixture?
Homogeneous – same throughout, uniform, do not see visible parts
Heterogeneous – not uniformly mixed, can see different parts
What are the sites of protein synthesis?
ribosomes
Identify the figurative language being used.
The test was an albatross hanging over her.
A.alliteration
B.metaphor
C.simile
metaphor
What is the equation to find displacement?
displacement = initial velocity times time plus half the acceleration times time squared
Define: monomer
1) A molecule that may react chemically to another molecule of the same type to form a larger molecule, such as dimer, trimer, tetramer, polymer, etc.
(2) The simplest unit, or the repeating unit, of a polymer.
What does “amu” stand for? What is it defined as?
Atomic mass unit – 1/12 (one twelfth) of a Carbon atom
What is the role of LYSOSOMES in metabolism?
DIGESTION
Lysosomes are organelles that contain digestive enzymes. They digest excess or worn out organelles, food particles, and engulfed viruses or bacteria. Lysosomes are like the stomach of the cell.
TRUE OR FALSE?
The punctuation is correct.
someone with twelve year’s experience
false
What are Newton's 3 laws of motion?
Newton's first law states that every object will remain at rest or in uniform motion in a straight line unless compelled to change its state by the action of an external force. This is normally taken as the definition of inertia.
The second law explains how the velocity of an object changes when it is subjected to an external force. The law defines a force to be equal to change in momentum (mass times velocity) per change in time. F = m * a
The third law states that for every action (force) in nature there is an equal and opposite reaction.
Define: CATABOLISM
the breakdown of complex molecules in living organisms to form simpler ones, together with the release of energy; destructive metabolism
C-12 and C-14 are isotopes. What does that mean?
Same number of protons and different number of neutrons
