1
This diagram is most likely used to represent the theory that suggests
New species arise after rounds of massextinction.
All species share a common ancestor and change over time
Speciation happens quickly with no change in between
All species started at the same time, some are now extinct
2
During photosynthesis, the sun's radiant energy is converted into which form of energy?
Kinetic
Electical
Mechanical
Chemical
3
DDT=Pesticide. How did banning DDT in 1972 affect the US population of Bald Eagles?
Eagle population increased and then quickly decreased
Eagle population slowly increased
Eagle population rapidly declined.
Eagle population was not affected
4
How would black fur on parts of a Himalayan rabbit affect warmth for those areas?
Black fur absorbs more heat
Black fur insulates better
Black fur reflects more heat
Black fur generates more heat
5
Weed killer resistance=dominant. What % of the offspring would be resistant to weed killer?
50%
0%
100%
25%
6
Which process will decrease the amount of oxygen measured in a container?
Photosynthesis
Osmosis
Respiration
Mitosis
7
During the winter, Himalayan rabbit's fur grows in black. Color change could be negative b/c?
Does not absorb heat like white fur
Makes them easier for predators to see
Reduces chances of finding a mate
It is thinner than white fur
8
Colorblindness carried on the X chromosome. A boy is born colorblind, which HAS to be true?
His Mom carried the color blindness gene
His father had normal vision
His grandmother was colorblind
His grandfather passed on colorblindness to his dad
9
Raising ocean temperatures cause algae to leave coral. Which human influence responsible?
Shoreline erosion
Burning fossil fuels
Introduction of non-native species
Solar power generation
10
Which person could not pass on the allele for sickle cell disease to her/his children?
Z
V
X
Y
11
The presence of which structure indicates this cell is capable of locomotion?
Ribosome
Cytoplasm
Flagellum
Cell wall
12
What are the possible genotype(s) of person 6? Unaffected=dominant
ZZ and Zz
ZZ, Zz, and zz
ZZ and zz
Zz
13
A decrease in the fox population would result in...
Increase in the owl population
Decrease in rabbit population
Decrease in the chipmunk population
Increase in the grasshopper population
14
Based on this diagram, monarch and viceroy butterflies belong to the same
Subfamilies
Family
Species
Genus
15
There is a drop in then number of trout over a period of time. What caused the trout decline?
Migration of blue herons out of the area
Application of insecticides to areas where mosquitoes breed
New conservation laws that protect the wetland
Introduction of a predator that feeds on blue heron eggs
16
Which structure is not found in fungi keeping them from doing photosynthesis?
Cilia
Nuclei
Chloroplasts
Mitochondria
17
The current cheetah pop. is close to extinction. What is a result of limited genetic variation?
Survival rate of young has increased
Less able to adapt to changing environmental conditions
More resistant to disease
Cheetahs have to interbreed with other species
18
What is a likely result of decreasing coyote populations?
Increase in goat population
Increase in mouse population
Increase in grass population
Decrease in hawk population
19
What gas does PHOTOSYNTHESIS release into the atmosphere?
Carbon dioxide
Nitrogen
Hydrogen
Oxygen
20
Louis Pasteur invented which process for killing bacteria? Used for milk today.
Fermentation
Pasteurization
Differentiation
Homeostasis
21
A major concern related to testing of a new herbicide (weed killer) on local environment
Increase genetic diversity of weed population
Use of atmospheric CO2 gas for photosynthesis
Runoff or absorption of weed killer by local water source
The weed killer would effect desirable plants nearby (crops)
22
Bacteria reproduce asexually, and mammals reproduce sexually. How do the offspring differ?
Both ways provide great genetic diversity
Asexual=clones of parent. Sexual=mix of genes from 2 parents
Sexual=offspring clones of parent. Asexual=mixed genes
23
Energy produced by cellular processes is stored as
CO2
RNA
DNA
ATP
24

100%
50%
75%
25%
25
Type B blood more common on an isolated island than on mainland. Why?
Island conditions less favorable for Type B individuals
Natural selection only happened on mainland
Random mutations in island population
Genetic drift reduced occurrence of Type A blood
26
Which two are most closely related?
Fermaldiapandurata and Ficus pandurate
Castillaelastica and Ficus elastica
Ficus benjamina and Ficus lyrata
Bromusjaponicus and Ipomoea violacea
27
Use the taxonomic key to identify the species of the following insect
Problematica alva
Problematica brancus
Problematica cantrellis
Problematica differensis
28

Second level consumers
Third level consumers and producers
Second and third level consumers
Producers
29

Lepus insularis
Sylvilagus aquaticus
Lepus callotis
30
Which statement supports the position that viruses are NOT living?
Viruses infect both plants and animals
Viruses replicate to produce more viruses
Viruses have genes encoded in DNA
Viruses require a host cell to reproduce
