1
Which of these would lead to a lower rate of photosynthesis in a plant?
increase in the amount of carbon dioxide in the air
decrease in the amount of carbon dioxide in the air
increase in the amount of oxygen in the air
decrease in the amount of oxygen in the air
2
Which statement describes a way in which cellular respiration differs from photosynthesis?
CR provides energy for the cell
CR releases carbon dioxide
CR is carried out in one specific organelle
CR consists of 2 phases
3
What is the result of the fertilization of an egg?
gives offspring more chromosomes than the parents
restores the diploid number of chromososmes
deletes polypeptide chains in the chromosome
gives offspring fewer chromosomes than the parents
4
Two gametes with 20 chromosomes fuse. How many chromosomes will the zygote contain?
80
20
10
40
5
What fate would result from the inability of a species to reproduce?
species would continue to thrive
species would become extinct
species would mutate
species would increase
6
Why does a gopher snake produce a hiss that sounds like a rattlesnake’s rattle?
to attract a mate
to increase adrenaline flow
to attract prey
to confuse predators
7
Which of these shows the steps by which proteins are coded and synthesized?
DNA - RNA - protein
protein - RNA - DNA
protein - DNA - RNA
RNA - DNA - protein
8
Which best explains the relationship among the cell structures in making protein?
nucleus makes protein, protein travels Golgi, ribosome folds
Golgi makes protein, DNA codes ribosome to fold
nucleus directs Golgi to make protein, ribosome surrounds
nucleuscodes, protein assembled in ribosome, moved to Golgi
9
What is the role of hydrogen bonds in the structure of DNA?
to connect the base pairs
to synthesize proteins
to code for proteins
to separate the strands
10
What will happen to a cell that has a solute conc of 1% when placed in a 5% saltwater solution?
shrink, less water outside than inside
burst, more water inside than out
burst, more water outside than in
remain same, equal water on both sides
11
How many daughter cells are formed in meiosis?
0
2
4
1
12
Which of these directly allows blood cells to transport oxygen to various parts of the body?
antibodies
hemoglobin
platelets
carbon dioxide
13
An introduced snake caused a decline in mice and an increase in the snake. Why?
mice were the snake prey
snakes dominated, mice left
competition
peopled killed mice, snakes increased - loss of predator
14
Polar bears use sea ice while hunting seals. What result will continued global warming have?
polar bear decrease, seal increase
polar bear decrease, seal no change
polar bear increase, seal decrease
both polar bear & seals increase
15
What is the difference between the way animals and plants exchange gases with their enviro?
animals photo & cell respiration plants only cell resp
animals only cell respiration plants photo & cell resp
animals photo & cell respiration plants only photo
animal only photo plants photo & cell respiration
16
Which cross will produce the greatest number of genotypic and phenotypic variations?
RR x RR
Rr x RR
rr x rr
Rr x Rr
17
Which structure is primarily responsible for directing all processes of a plant cell?
chloroplast
nucleus
lysosome
mitochondria
18
Which process allows for an organism to increase the number of body cells during development?
mitosis
meiosis
budding
conjugation
19
Which effect will a forest fire most likely have on secondary consumers in the ecosystem?
energy increase, less competition
energy decrease, fewer primary consumers
energy increase, fewer predators
energy constant, consumers don't need producers
20
A strand of DNA is exposed to intense heat. What will likely happen to the strand of DNA?
nitrogen base pairs in the DNA molecule will switch places
chemical bonds of the DNA molecule will be strengthened
chemical bonds of the DNA molecule will be broken
More nitrogen base pairs will add on to the DNA molecule
21
Which abiotic factor limits the altitude at which plants can grow?
presence of a parasite
temperature of the area
concentration of soil microbes
presence of herbivorous animals
22
A reduction in which of these would lead to a decrease in all other populations in the web?
snake
grasshopper
coyote
grass
23
How would a drop in temperature affect cell respiration and photosynthesis
photo increase, CR decrease
Photo decrease, CR increase
both remain same
both decrease

a change in the production of enzymes
26
Some species survive & others do not in a changing environment is best explained by
law of segregation
biological magnification
alternation of generations
natural selection
27
what is the main function of a selectively permeable cell membrane?
storage of water
regulate what enters/exits cell
break down molecules
