2
Natural selection is the process by which
organism evolve towards perfection

3
Which of the following is a biotic factor?

4
One of the conditions required to maintain genetic equilibrium is
no movement into or out of the population

natural selection
mutations
5
What field of biology deals with classifying organisms?
organization
hierarchy
nomenclature

6
The following is an example of a
biomass pyramid

7
Why did development of sexual reproduction speed up the process of evolution?
sexual reproduction limits genetic variety
sexual reproduction occurs faster than asexual reproduction
sexual reproduction increases genetic variety
in sexual reproduction offspring identical to parents
8
Which of the following lists the seven levels of classification in the correct order?
kingdom,phylum,order,class,family,genus,species
kingdom,phylum,family,order,class,genus,species
kingdom,phylum,class,order,family,genus,species
kingdom,phylum,family,class,order,genus,species
9
In the scientific name, the species is
capitalized and written after the genus

lowercase and written after the genus
capitalized and written before the genus
10
If allowed to self pollinate, true breeding white flowered pea plants always
are polllinated by hand
are heterozygous
produce offspring with only pink flowers
produce offspring with only white flowers
11
Which kind of selection would most likely lead to two distinct populations?
Stabilizing Selection
Disruptive Selection
Directional Selection
Genetic drift
12
Genotype of a pea plant with wrinkled seeds is rr. The genotype of the wrinkled gamete parent
RR
r
wrinkled
rr
13
Sucrose, glucose, fructose and galactose (ending OSE) are all
amino acids
lipids
carbohydrates
proteins
14
In gene recombination the same restriction enzyme must be used to cut donor DNA and plasmid
since plasmids must be inserted into bacteria
for antibiotic resistance genes are part of the plasmid
so that introns will be removed
because sticky ends must match
15

homeostasis
reflex
feedback inhibition
nervous response
16
Cell membranes are composed of
amino acids
lipid(phospholipids) and proteins
carbohydrates and protein
protein and nucleic acids
17

karyotype
Pedigree
Punnett square
monohybrid cross
18
The following is an example of
Stabilizing Selection
Unselction
Directional Selection
Disruptive Selection
19

Adenosine triphosphate; 3
Adenosine triphosphate; 2
22
A human fertilization occurs in the
ovary
fallopian tube
uterus
seminiferous tubule
23
Evolution can be a result of
No mutations whatsoever and no changes

mitosis)
meiosis
cytokinesis
asexual

enzyme
28
Offspring that result from asexual reproduction
have the same DNA but not the same chromosomes
are different from the parent
are identical to the parents
might seem the same but are different from the parent
29
Plants having wrinkled seeds (rr) and a plants having round seeds (RR) are said to be..
homozygous for seed shape
dominant
