Test Description: Review for quarterly
Instructions: Answer all questions to get your test result.
1) Which description best supports that squirrels are sexually reproducing organisms?
A
Squirrels can reproduce at a couple months old.
B
The breeding season for males and females varies from year to year.
C
The habitat of squirrels includes open grassy areas and trees
D
They have a very thick coat of hair and can see extremely well.
2) Some scientists claim the gene that controls the production of the proteins for fur color is located on a chromosome. Which of the following provides evidence to support the claim?
A
All squirrels with this gene have brown fur color.
B
Some squirrels have this gene in a different location.
C
The proteins for fur color is responsible for other traits in squirrels.
D
Other mammals with white fur have genes located in similar locations.
3) Some scientists claim the gene that controls the production of the proteins for fur color is located on a chromosome. Which of the following provides evidence to support the claim?
A
The proteins for fur color is responsible for other traits in squirrels.
B
Other mammals with white fur have genes located in similar locations.
C
Some squirrels have this gene in a different location.
D
A mutation in this gene may cause a variation of fur color.
4) If a white squirrel that lives in the woods in Odenton is born with this as a mutation, what prediction can be made about the mutation?
A
This mutation would be neutral because fur color will not affect the survival of the squirrel.
B
This mutation would be a harmful mutation because it would make the squirrel more visible to predators.
C
There is no way to determine if this mutation would be beneficial, harmful or have no effect at all.
D
This mutation would be beneficial because it would help the squirrel blend into the environment.
5) Chromosomes play an important role in variation because they _________________
A
regulate protein production
B
none of the above
C
deliver information from the environment
D
release energy
6) The main effect of a genetic mutation is to _________________.
A
reduce the life span of organisms
B
keep the genes the same
C
increase rate of reproduction
D
change a protein produced by the organism
7) What is true about squirrel reproduction?
A
. All offspring are identical genetically to each other.
B
They reproduce sexually because two parents contribute genetic material to the offspring.
C
The offspring are always genetically identical to both of their parents.
D
. A set of identical chromosomes is passed on to the offspring
8) What is true about squirrel reproduction?
A
All offspring are identical genetically to each other.
B
The offspring have genetic variation.
C
A set of identical chromosomes is passed on to the offspring.
D
The offspring are always genetically identical to both of their parents.
9) Explain how it is possible for two brown furred squirrels to have a white furred offspring?
A
If both parents are heterozygous.
B
If each offspring gets 100% of its genes from each parent.
C
If the parents have asexual reproduction.
D
If both parents are homozygous dominant.
10) Through the years, certain traits in watermelons were selectively bred by humans. Which of the following is true about selective breeding of watermelons?
A
The traits of seed size and peel color have been artificially selected in watermelons.
B
The oval shape of the watermelon has been artificially selected.
C
The traits of taste and seed size have been artificially selected in watermelons.
D
The attractiveness of the fruit to wild animals has been artificially selected.
11) Which of the following is the best example of artificial selection?
A
Fruit with large seeds are difficult to reproduce.
B
Pollination by bees is part of the process of artificial selection.
C
Certain fruits may become unavailable because of disease.
D
The most desirable traits were selected to reproduce.
12) By using gene therapy in fruits and vegetables, they will
A
Have an increased risk of disease.
B
Be affected by other diseases.
C
Have a new defense against disease.
D
Not have anything to treat the diseases.
13) Certain animal behaviors increase
A
food intake
B
reproductive success
C
mortality rate
14) How do animals help with plant reproduction?
A
They eat the leaves.
B
They eat the seeds and poop them out elsewhere.
C
They camouflage themselves to the color of the plants.
