Carbon dioxide that a plant takes in through itsleaves
Water that a plant takes in through its roots.
Sugars that a plant makes
2
A pea plant that has two different alleles for the same trait is said to be…
Homozygous
Heterozygous
3
A variable that is deliberately changed in an experiment is the...
Dependent variable
independent variable
controlled variable
none of these
4
Many plants droop without water and "straighten up" with water, because ...
Water enters through the stomata
Water enters and expands the plant cells.
Water reacts with, and stiffens, the cell walls.
Water is used to generate energy that moves the plant.
5
During cell division, chromatin condenses into thread like structures called...
chromatin
DNA
RNA
chromosomes
6
During respiration, animals release CO
2
and plants release O
2
False
True
7
Organisms that reproduce sexually differ from organisms that reproduce asexually by:
smaller chance offspring will survive environmental change
a smaller energy cost involved in reproduction
a greater number of offspring
a greater genetic variation among their offspring
8
Together, the G1 phase, S phase, and G2 phase are called…
interphase
telophase
metaphase
prophase
9
Gametes have half the number of chromosomes found in body cells and is said to be ...
diploid
haploid

11
Natural selection produces evolutionary change by ...
Reducing the number of new mutations.
Increasing the number of new mutations
Producing genes needed for new environments.
Changing the frequency of various versions of genes.
12
To be classified as living ...
a. An object must obtain and use energy.
a. An object must be able to move.
a. An object must possess a cell nucleus.
a. An object must be able to breath.
13
Cellular respiration occurs only in the presence of oxygen.
True
False
14
In a diploid organism, what do we mean when we say that a trait is dominant?
None of the choices is correct
It is stronger than a recessive form of the trait.
more of the gene product than is the recessive trait.
when the dominant traits' allele is there, it is expressed
15
During respiration, animals release O
2
and plants release CO

True
False
16
In which way are plants and animals different in how they obtain energy?
Plants capture energy from sun; animals use chemical energy
Plants use energy directly; animals must transform it
Animals use ATP; plants do not
Animals use energy directly; plants must transform it
17
Plant cells have large, persistent vacuoles; animal cells have small, temporary vacuoles
True
False
18
What is the primary change that occurs gradually over time in a population?
Mutations occur to meet the needs of the population
Individual organisms change traits to be successful
Proportions of organisms having different traits change
19
The cell membrane of animal cells is semi permeable; the cell membrane of plant cells is not.
False
True
20
As a cell becomes too large, it will usually divide to form two of these kinds of cells
Son
Sibling
father
daughter
21
During respiration, both animals and plants release CO
2
•
False
True
22
The plants that Mendel crossed to produce the F1 generation are from this generation
F1
F3
F2
Parent
23
Both plant cells and animal cells replicate by mitosis.
False
True
24
Plant cells can contain chloroplasts (but may not); animal cells do not contain chloroplasts
False
True
25
Darwin's theory of evolution by natural selection states that evolution occurs because:
intelligent organisms are best suited for an environment.
Changes in genetic material are usually harmful.
Natural selection acts on variation in a population.
Natural selection is awesome
26
How similar is your genetic information to that of your parents?
You get one allele of each gene from each parent
You have the same genes your parents got from their parents
you get more from the parent that is the same sex as you
27
How does glucose provide energy to your cells?
The energy of the glucose is transferred to CO2 and H20
energy of glucose is transferred to other molecules like ATP
Glucose creates ATP
Glucose is digested into simpler molecules
28
Photosynthesis requires light, water, carbon dioxide, and ...
stars
chlorophyll
DNA
nitrogen
29
According to the cell theory, new cells are produced from exsisting
organs
cells
bodies
organelles
