Which of the following utilize DNA as their genetic material? - ANS ✔✔A, B, and C
Which of the following is not characteristics of life? - ANS ✔✔Once a species is formed it remains the
same for perpetuity
Which taxonomic sequence is correct? - ANS ✔✔Domain, kingdom, phylum, class, order, family, genus,
species
Darwin proposed the theory of evolution through the process of natural selection. Darwin used to term
natural selection to mean - ANS ✔✔Some heritable traits of a population are selected for (or against) by
environmental conditions
A friend of yours calls to say that his car would not start this morning. He asks for your help. You say that
you think the battery must be dead. If so, then jump-starting the car from a good battery will solve the
problem. In doing so, you are __ . - ANS ✔✔Stating a hypothesis and using that hypothesis to make a
testable prediction
The reactive properties (chemical behavior) of an atom mostly depend on the number of: - ANS
✔✔Electron in the outer electron shell of the atom
Water molecule form hydrogen bonds because - ANS ✔✔The water molecule is polar
Nitrogen has an atomic number 7; therefore, it has __ electrons in its outermost electron shell - ANS
✔✔5
In the following reaction, what type of bond is holding the two atoms together (K + Cl -> K+ + Cl- -> KCL) -
ANS ✔✔Ionic
Why is it possible to float a needle on the surface of water? - ANS ✔✔The surface tension that is a result
of water's cohesive properties make this possible. Hydrogen bonding waker water cohesive
A single carbon atom can form a maximum of __ covalent bond(s) - ANS ✔✔4
The four most abundant elements in the human body are: - ANS ✔✔Hydrogen, carbon, nitrogen, oxygen
The five most abundant elements in DNA and RNA are: - ANS ✔✔Hydrogen, carbon, nitrogen oxygen,
phosphate
What are the roles of lipids in the human body? - ANS ✔✔Long term energy storage, hormones
(steroids)
, How is it possible for an antibiotic medicine to target the infecting bacterial cells but not the human cells
of the patient's body? - ANS ✔✔Antibiotic medicines target structures, such as bacterial cell walls, that
bacteria have but human cells do not
The three domain of life described by biologists today are Bacteria, Archaea, and Eukarya. What is the
principal difference between eukaryotes (domain Eukarya) and prokaryotes (domains Archaea and
Bacteria)? - ANS ✔✔In eukaryotes, the interior of the cell is divided by internal membrane into
specialized compartments; special organelles such as mitochondria
This diagram represents osmosis of water across a semipermeable membrane. The U shaped tube on the
right shows the results of the osmosis. What could you do to level the solutions in the two sides of the
right-hand U tube? Remember, water will always move towards the more hypertonic solution. - ANS
✔✔Add more solute to the left-hand side
Which of the following represents the energy of activation in the presence of an enzyme? (Graph) - ANS
✔✔B
Below is part of a metabolic pathway. What happens if Enzyme2 is defective and non-functional? - ANS
✔✔Substrate Y would not be metabolized, so it would increase in amount
Some prokaryotic and all eukaryotic cells use oxygen to harvest energy from food molecules. In what
form is that harvested energy available to power cell work? - ANS ✔✔ATP molecules
Fat molecules store 9 kcal per gram. There are about 454 grams in a pound of fat, so one pound of fat
stores about 4,000 kcal energy. If running at a moderate pace for one hour burns about 800 kcal energy,
how many hours must a person run to burn the energy stored in one pound of fat? - ANS ✔✔5 hours
Photosynthesis contributes to plant growth by __. - ANS ✔✔Taking in carbon dioxide and making sugars
(carbohydrates)
Which of these is an advantage of biofuels from food crops? - ANS ✔✔all of the above
A plant with purple flowers is allowed to self- pollinate. Generation after generation, it producers purple
flowers. This is an example of: - ANS ✔✔Pure- breeding "true- breeding"
What are Alleles - ANS ✔✔Are alternative forms of a gene
A cross between homozygous purple-flowered and homozygous white-flowered pea plants results in
100% of the offspring having purple flowers. This demonstrates - ANS ✔✔Dominance by the purple
allele
What was the most significant result Gregor Mendel drew from his experiments with pea plants? - ANS
✔✔Traits are inherited in dischete units, and are not the results of " blending"
What is a genetic cross called between an individual of unknown genotype and a homozygous recessive?
- ANS ✔✔A testchess
