Answers
1
Which process occurs immediately after transcription (shown in pic) during protein synthesis?
meiosis
osmosis
verification
translation
2
Which step in the conversion of ATP to ADP provides energy for body processes?
sugar is removed from ATP
phosphate bonds are broken
phosphate bonds are created
sugar is added to ATP
3
What would be
least
likely to limit the type of animals that can survive in an aquatic habitat?
the level of salt dissolved in the water
the shape of water waves
the level of oxygen dissolved in the water
the range of water temperatures
4
Haploid cells regain a diploid number of chromosomes in which of the following processes?
transcription
respiration
translation
fertilization
5
Which is the
least
important reason for one to share research with the scientific community?
so that you may receive widespread publicity for your work
so others with similar studies may compare your work
so that your work may be reviewed by other scientists
so others may consider yours while planning future studies
6
Which does the DNA sequence shown represent?
a section of a gene that has instructions for making protein
the structures mitochondria use to release energy in cells
a protein made from nucleotide pairs coded on transfer RNA
a protein that produces oxygen inside cells
7
Which statement
best
predicts the behavior of water molecules in the cell and in the solution?
The number of water molecules in the solution will increase.
The number of water molecules in the cell will not change.
The number of water molecules in the cell will increase.
The number of water molecules in the solution will decrease
8
Which statement gives the
best
explanation for the different shell types of these tortoises?
Random spontaneous mutations led to different shells.
Different shells evolved as they adapted to food sources.
To prevent competition, the tortoises evolved differently.
The need to attract different mates led to different shells.
9
What is the main role played by small invertebrates in the ecosystem in the pyramid shown?
primary consumers
producers
secondary consumers
top predators
10
DNA is replicated before the cell divides during mitosis. What is the purpose of this process?
So the new cell has a complete set of correct chromosomes.
It increases the rate of cellular repair inside tissues.
Rearranges the nucleotides so different tissues can be made
It makes mutations that stop the expression of lethal traits
11
Which process produces energy by breaking down glucose?
photosynthesis
metamorphosis
cellular respiration
active transport
12
Which of the following is a correct explanation of the structure of DNA?
monomer formed from subunits of four kinds of nitrogen bases
polymer formed from subunits of four kinds of nitrogen bases
a polymer formed from subunits of four kinds of carbon bases
a monomer formed from subunits of four kinds of carbon bases
13
Protein is made by the ribosomes in the cell. They are found on the surface of which organelle?
mitochondrion
rough endoplasmic reticulum
golgi apparatus
nucleus
14
Which organisms bring in the energy that is ultimately distributed through the energy pyramid?
large fish
small invertebrates
small fish
plankton
15
How could global warming lead to the extinction of polar bears?
Many new plants lead to a decrease in the bear's food supply
Gases escape from the melting ice, making it hard to breathe
Less ice makes it hard for the bears to hunt their prey.
Warmer air and water temps lead to overheating in the summer
16
If the temp outside rises but the light intensity stays the same, what affect will it have?
a decrease in the rate of photosynthesis
an increase in the rate of photosynthesis
no change in the rate of cellular respiration in plants
no change in the rate of photosynthesis
17
1 parent is heterozygous for a trait; the other is homozygous recessive. How about their kids?
50% chance of having the trait
75% chance of having the trait
25% chance of having the trait
100% chance of having the trait
18
Each DNA molecule in a cell forms __________.
two pairs of chromosomes
a pair of chromosomes
a single chromosome
half of a chromosome
19
Which event would be
least likely
to cause a reduction in the biodiversity of an area?
volcanic eruption
acid rain
gradual climate change
introduction of an exotic species
20
Which two species are
most
closely related?
Drosophila simulans and Drosophila melanogaster
Drosophila ananassae and Drosophila melanogaster
Drosophila melanogaster and Drosophila sechellia
Drosophila simulans and Drosophila sechellia
21
Which scientist's work supported Darwin's suggestion that new species came from old species?
Mendeleev: carbon is essential for many organic processes.
Mendel: traits are passed from one generation to the next.
Louis Pasteur: certain diseases are caused by microorganisms
Robert Hooke: observations of cells under a microscope
22

6
H
12

6
?
respiration in eagles
fermentation by yeast
photosynthesis in algae
decomposition by bacteria
23
What special function do red blood cells perform in the human body?
they hold nutrients
they carry oxygen
they hold genes
they carry water
24
What is this molecule, which is important for the production of ATP?
lipid
protein
carbohydrate
nucleic acid
25
Which does
not
support the theory that whales and dolphins shared a common ancestor?
they use a very similar actions to prey on schools of fish
they produce a very similar sequence of amino acids
they have a very similar order of nucleotides in their DNA
they go through very similar events during fetal development
26
What is the
best
explanation for the increase in top predators?
an increase in the size and availability of prey
an increase in competition among primary consumers
a decrease in the size and number of producers
a decrease in the availability of fresh water
27
