6
Which of the following specie(s) are most likely to have the greatest population?
Hawk,Snake
Snake, Lizard
Hawk
Mouse, Rabbit, Grasshopper
7
What order shows a correct flow of energy in this ecosystem?
Hawk-Snake-Mouse-Plants
Plants-Rabbit -Snake- Lizard
Lizards-Snake-Rabbit-Plants
Plants-grasshopper-lizard
8
Why do scientist study embryos during the early stages of development?
This is the cheapest way to study organisms.
It is easier to see the organism.
The organism cannot escape, easier to study.
Organisms are more similar during the early stages
9
What happens to the body when an organism dies?
They build up because they are not biodegradable
Gets vaporized and vanishes
Converted right into energy.
Gets broken down by decomposers & scavengers then recycled.
10
What is the chance of having homozygous offspring?
3 out of 4
2 out of 4
1 out of 4
0 out of 4
11
If a massive environmental change happened which would have a better chance to survive?
Organisms with similar genotypes
Organisms that live in an isolated area.
Organisms with great genetic diversity
Organisms with little genetic diversity
12
Which best describes how the picture works?
Incomplete dominance
Mutations
Codominance
Inheritance by dominance
13
What statement best describes sexual reproduction?
Traits are controlled by the male's genes.
Traits are determined by genetic info from each parent
Each trait is controlled by one parent
Traits are controlled by the female's genes.
14
Which of the following statements correctly describes sexual reproduction?
Offspring have half as much DNA as their parents.
Offspring have twice as many genes as their parents.
Offspring have 1 copy of every chromosome from their parents
Offspring receive one allele for each gene from each parent
15
What is the best explanation of Selective breeding?
Organism is cloned so an exact copy of the DNA passed down
When one generation is bred together to keep the similar DNA
An organisms DNA is altered artificially
Organisms with certain traits are bred together
16
What cell part does photosynthesis occur in?
Lysosomes
Chlorophyll
Mitochandria
Chloroplast
17
How confident do you feel about taking the trimester exam?
I feel pretty confident!
I am going to study first and then ACE this Exam!
I am not going to jinx myself so I am going to say alright.
I am about to ACE this
18
The origin of all the energy in this ecosystem is from the what?
Plants
Primary Consumers
Sun
Producers
19
What would most likely happen to the food web if there was an increase in the mouse population?
Grasshoppers & rabbits would increase while lizards decrease
Snakes would increase while hawks would decrease
Hawks and snakes would decrease
Snake's population would increase and plants would decrease
20

21
42
23
21
To start photosynthesis plants need carbon dioxide, sunlight and _______________?
Alcohol
Oxygen
Water
Sugar
22
What is the chance the offspring will show the dominant trait?
3 out of 4
1 out of 4
4 out of 4
2 out of 4
23
How are genes and traits connected?
The traits directly control the genes.
There is no connection
Genes directly determine the expressed trait.
Traits and genes are the something.

Chloroplast & Cell wall
Chloroplast & Vacuole
Cell wall & Vacuole
Chloroplast & Lysosomes
25
