1.
What is the difference between INTERPHASE and all the stages of mitosis (prophase, metaphase, anaphase, telophase
a)
Mitosis is the cell acting as a regular cell, while interphase is the cell dividing and creating a new cell
b)
Interphase is the cell acting as a regular cell, while mitosis is the cell dividing and creating a new cell
2.
Compare the number of cells in INTERPHASE of the root tip to the leaf.
Choose the best explanation for the difference in the number between the two plant structures
a)
Root tip has more cells in INTERPHASE than mitosis because the roots are continuously growing throughout the lifespan of the plant
b)
Leaf cell has more cells in INTERPHASE because it has to do photosynthesis and cellular respiration.
3.
Why is the elphant considered a keystone species?
a)
If you remove the elephant from its ecosystem, other animals/ plants will have trouble finding water and getting seed dispersal completed
b)
If you remove the elephant from its ecosystem, poachers will have no source of income
c)
If you remove the elephant from its ecosystem, other animals will not be able to find niches
4.
Humans hunted the elephant for the ivory tusks. Because of the 20 year war, large numbers of elephants were killed for their tusks. The surviving elephants were tuskless, and when they reproduced, passed the trait for tusklessness to the offspring. Over time, more and more elephants were born tuskless versus those that still had tusks.
Which type of elephant had an ADVANTAGE over the ivory tusk hunters?
a)
Those with tusks
b)
Those with no tusks
c)
Those with small tusks
d)
All of the above are advantages
5.
What is main reason why ALL organisms undergo cellular respiration?
a)
To get rid of excess oxygen
b)
To generate an energy source by making ATP
c)
To use up all of the glucose (C6H12O6) that has entered the organism from food
d)
ALL of these are reasons why organisms undergo cellular respiration
6.
What is the scientific explanation for this change in the tusk/ tusklessness trait over time?
a)
Cellular respiration
b)
Poaching
c)
Natural selection
d)
Mitosis
7.
Which of the following would be an abiotic limiting factor on a population's ability to continue to grow?
a)
Competition
b)
Predation
c)
Natural Disasters
d)
Parasitism and Disease
8.
Use the diagram below to decide which ones are REACTANTS for photosynthesis, and which ones are PRODUCTS
a)
Reactants: 1, 2, 3 Products: 4, 5
b)
Reactants: 1, 3, 5 Products 2, 4
c)
Reactants 4, 5 Products: 1, 2, 3
d)
Reactants 2, 4 Products: 1, 3, 5
9.
The three animals below are able to co-exist in the same habitat in the same time period. What phenomenon describes this?
a)
Niche Partitioning
b)
Rule of 10%
c)
Detritovores
d)
Phylogenetics
10.
Which statement below best explians how photosynthesis help the process of cellular respiration to occur?
a)
Cellular respiration cannot occur without using the products of photosynthesis
b)
Cellular respiration cannot occur without using water and carbon dioxide from photosynthesis
c)
Cellular respiration cannot occur withour using water from transpiration
d)
Cellular respiration only happens in plants
11.
Why does a SEED need to undergo the process of mitosis?
a)
To grow bigger
b)
To perform photosynthesis
100 %
