100 REAL EXAM QUESTIONS AND CORRECT DETAILED
ANSWERS |ALREADY A GRADED | NEW AND REVISED .
An object at rest has no ______ energy, but it may have _____
energy resulting from its location or structure. - ANSWER-
kinetic....potential.
Which of the following is a measure of randomness in a system?
– ANSWER-Entropy.
Diffusion is an example of ______. - ANSWER-Passive transport.
Which of the following are
true? A) Most enzymes are
lipids.
B) An enzyme's function is unaffected by antibiotics.
C) Enzymes are the reactants in a chemical reaction.
D) Enzymes catalyze specific reactions.
E) An enzyme's function requires inhibitors. - ANSWER-C)
Enzymes are the reactants in a chemical reaction.
If placed in tap water, an animal cell will undergo lysis (refers to
the breaking down of the membrane of a cell) Whereas the plant
,cell will not. What accounts for the difference? - ANSWER-The
relative inelasticity and strength of the plant cell wall.
Read the following scenario to answer the following question(s).
Cellular respiration converts the energy of fuel molecules to a
form of energy that a cell can use to perform work. In an average
day, most adult humans need to consume about 2,000 Calories to
maintain their health. However, the exact amount of dietary
Calories a person needs depends upon many factors, including
the person's age, physical activity, size, and health. Foods that
we consume vary greatly in their nutritional content and quality. A
large hard-boiled egg, for example, has about 75 dietary Calories
and contains about 70% of our recommended daily intake of
cholesterol.
Molecules that come from the food we eat provide energy for the
amazing work that goes on inside of our cells. This energy, stored
inside of our food, is a form of ______. - ANSWER-Potential
energy called chemical energy.
When two solutions that differ in solute concentration are placed
on either side of a selectively permeable membrane, and osmosis
is allowed to take place, the water will ______. - ANSWER-Exhibit
a net movement to the side with lower water concentration.
, Which of the following is a function of the Gogli apparatus. -
ANSWER-Protein modification.
Vacuoles are _____. - ANSWER-Membranous sacs.
Cellular respiration can be described as the conversion of the
energy _____. - ANSWER-Stored in food molecules to energy
stored in ATP.
Read the following scenario to answer the following question(s).
The earliest cells detectable in fossils were different from the
cells in animals, plants, fungi, and protists living today. These
first prokaryotic cells gave rise to eukaryotic cells approximately
1.7 billion years ago. The structure of eukaryotic cells today
suggests how they might have evolved from their prokaryotic
ancestors. Scientists examining mitochondria and chloroplasts
now think that these organelles were probably free-living
prokaryotes before becoming a part of eukaryotic cells long ago.
Which of the following is a characteristic of chloroplasts that
suggests that they might have evolved from free-living bacteria? -
ANSWER-Chloroplast have their own DNA.
