where an organism lives
what an organism eats

Several species of finches, each with a different beak shape, were discovered on the Galapagos Islands. The best explanation of why these finches evolved a variety of beak shapes is that they adapted to
obtain different types of food
defend against different enemies
gather different nesting materials
perform different courtship rituals
Use the following information to answer the next question.
When similar species coexist in an area, they have slightly different niches. They do not compete for resources; instead they divide the resources among them.
6
1
The type of arrangement described is called
specialization
natural selection
artificial selection
resource partitioning
7

Commensalism, parasitism, and mutualism are examples of a dependence relationship called
niches
predation
symbiosis
extirpation
Use the following information to answer the next question.
The suckerfish, Echeneis, has a dorsal fin modified to form a sucker-like organ, which helps it attach to the underside of a shark. This interaction provides protection to the suckerfish, but it does not harm the shark.
8
1
What type of dependency does the given interaction suggest?
Parasitic
Mutualistic
Cooperative
Commensal
Use the following information to answer the next question.
Organism X lives in the body of organism Y. X feeds on nutrients from the body of Y without providing any benefit to Y. The nutrients that X takes from Y are needed by Y in order to survive.

This situation describes a relationship that is
parasitic
mutualistic
cooperative
commensal

The most likely reason a desert fox has larger ears than the other two species of foxes is to ensure that it can
regulate its body heat and temperature
detect impending danger
locate its potential prey
find running water
11
1
All phenomena listed are examples of
selection
mutation
variation
competition
12

Reproduction of this type is known as
budding
binary fission
sexual reproduction
asexual reproduction
13

The union of the male sperm cell and the female egg cell is reffered to as
pollination
fertilization
parthenogenesis
asexual reproduction
14

The difference in the neck amoung giraffes is referred to as
diversification
discrete variation
artificial selection
continuous variation
15

An offspring having the same traits as both of its parents is a result of
crossbreeding
pure breeding
artificial breeding
random breeding
16

A red flower and a white flower are crossed. If the offspring has all red flowers, then it can be concluded that:
red is a recessive triat and white is dominant
red is a dominant trait and white is recessive
red and white are both dominant traits
red and white are both recessive traits
17
1
It can be concluded that eye colour is a
heritable characteristic
dominant characteristic
recessive characteristics
non-heritable characteristics
18
1
The explanation for Charles's inability to play the piano is that playing the piano is a
heritable characteristic
recessive characteristic
dominant characteristic
non-heritable characteristic
19
1
Which of the following statements summarizes the given information?
Genes exist in pairs.
The human cell contains 46 chromosomes.
Chromosomes are composed of DNA and protein.
Genes determine hereditary traits.
20
1
Which of the following statements does not describe a major function of genetic material?
It replicates itself
It stores information
It transfers information
It catalyzes chemical reactions
21
1
Which of the following statements about cell division is not correct?
Mitotic division produces eight cells at one time
Mitosis takes place in somatic body cells
The process of meiosis occurs only in sex cells
The process of meiosis produces a total of four cells, during two divisions
22
1
Which of the following functions is not achieved through meiosis?
Sexual reproduction
Production of gametes
Growth and cellular repair
Recombination of genetic material
23
1
Mitosis is a type of cell division that is responsible for all of the following functions except
reducing the number of chromosomes by half
maintaining the number of chromosomes
helping in growth and cellular repair
increasing the size of the organism
24
1
An advantage of the jellyfish reproducing sexually is that sexual reproduction
produces identical offspring
allows for less crossing over of genetic material
requires less energy to complete
provides genetic variation in the offspring
25
1
In terms of energy consumption and the number of offspring that can be produced, asexual reproduction generally requires
a lot of energy and produces a lot
of offspring
a lot of energy and produces a
few offspring
little energy and produces a lot
of offspring
little energy and produces a few offspring

During the Industrial Revolution, natural selection affected the pepper moth population in that
lighter colouring became more common in the population
darker colouring became more common in the population
different predators consumed the
pepper moths
the population became extinct
27
1
The scenario is an example of
artificial selection
natural selection
evolution
cloning
28

Alberta farmers are raising high-quality cattle by using modern reproductive technologies such as
Cloning
natural selection
genetic engineering
artificial insemination
29

Compared to temperate regions, equatorial regions have
a larger number and variety of species
a smaller number and variety of species
fewer species with more variety
roughly the same number and variety of species, but with different characteristics from those in temperate regions
30
1
Which of the following categories has the highest species diversity on the planet?
Birds
Plants
Insects
Mammals
31
1
How many species of organisms are currently known to scientists?
thousands
millions
billions
trillions
32

A reasonable hypothesis to explain why no new Calvaria trees began growing is that
dodos are required to pollinate the Calvaria flowers
spice traders used Calvatia wood for buildings and fires
pollution made it impossible for young Calvaria trees to grow
the Calvaria nut had to pass through the digestive system of the dodo before it could begin to grow
33
1
A species like the grizzly bear is best described as
a biological species
an impacted species
an extirpated species
a bioindicator species
34
1
Which of the following reasons cannot be given as a cause of the decrease in worldwide biodiversity?
A greater dependence on wood for fuel
An increase in the demand for consumer goods
An increased need to clear land for agriculture
A decrease in human population growth in developing countries
35

Canada has designated many areas as national parks. According to a wildlife conservationist, the best reason to develop national parks is
to save the natural biodiversity of the area by maintaining the interactions that naturally occur there
to maintain a pristine region of land to be admired by all citizens now and into the future
to bolster local and provincial economies by providing a setting ideal for tourism
to stop the over-hunting of animals from legal and illegal hunting

cloning
random chance
mutating genes
