Define a biotic factor and an abiotic factor
Biotic factor is anything living in the environment, abiotic factor is anything not alive.
100
The feeding interaction that is a network through which both energy and matter move.
Food web

What happens when a population reaches carrying capacity?
An extra ten points if you can determine which type of growth this is
The population would stabilize since you have reached the maximum capacity
100
What are the 2 main difference between prokaryotes and eukaryotes?
Eukaryotes has organelles and can have multiple cells vs prokaryotes which do not have organelles and only one cells.
100
This property of water allows for water to have all of its special properties.
Polarity
200
Global winds is defined as what?
Unequal distribution of heat creates this (warm dense air rises, and cool air becomes dense and sinks)
200
This process, which turns nitrates/nitrites into N2 gas, is carried out by bacteria and decomposers.
denitrification
200
Name at least 3 density-dependent limiting factors and at least 3 density-independent limiting factors.
DD - parasitism, competition, disease, stress from overcrowding, predation, herbivory
ID - floods, wildfires, droughts, hurricanes
200
What are at least three examples of passive transport?
(I will add an extra 20 points if you can explain examples of what each of these are)
Diffusion
Facilitated Diffusion
Osmosis

Between Orange Juice (4.2), Grapefruit (3.5) and Lemonade (2.8), which one would contain the least amount of hydrogen?
Lemonade
300
A biome’s climate can be described by a graph of its average monthly temperature and average monthly precipitation. Explain what is going on in terms of temperature and precipitation based on the graph
Temperature is constant, rainfall varies
300
This part of the water cycle is a biological process shown by an arrow moving water from the land to the atmospheric water (H2O) - hint plants do this to release water vapor
Transpiration
300
What is the main reason why population has grown exponentially from now vs the 1800s
Modern medicine
300
What are the two organelles that are in plant cells but NOT animal cells
cell wall
central vacuole
300
What is the key difference in endothermic and exothermic reactions?
(If you are feeling brave, come up to the board and draw what an endothermic/exothermic graph would look like for 30 points extra).
Endo absorbs more energy, Exo releases more energy
Reactants for Endo have less bond energy, Exo has more bond energy.
400
This biome has warm, dry summers, and cool moist winters. The soil lacks nutrients and has periodic, with animals are commonly known as browsers
Temperate Woodland/Shrubland.
400
What are physical and chemical properties associated with? Name at least 3!
The cycle process exemplified by cloud formation, rain, lightning, and running water.
400
What are the four factors in describing populations
Geographic range
growth rate
age structure
Density and distribution
400
When a cucumber is placed in a pickling solution, it shrivels and becomes a pickle, what is happening in terms of tonicity.
Water is rushing out of the pickle to the saltier solution representing a hypertonic interaction.
400
What is the difference between a theory and hypothesis?
A theory has been worked on with years of research to back up evidence found where as a hypothesis is to test observations just discovered.
500
Create an example of a structural, behavioral and physiological adaptation
structural is anything physical appearance
behavioral is how an organism acts
physiological based on the body's chemistry and metabolism
500
What cycles of matter will Phosphorus go through?
Hydrosphere
Biosphere
Geosphere

Murray is observing a bacterial colony that is growing in agar in a Petri dish. Agar is processed seaweed. Murray calculates that the population doubles in size every 32 hours. What can we determine from this statement?
Bacteria will continue to grow exponentially
500
What is the main difference for a unicellular and multicellular organism to maintain homeostasis?
Unicellular need to commit one cell to grow, transform energy and reproduce but multicellular organisms have multiple cells that are specialized for specific tasks.

Coach Damien notices that some of his football players drink more water than others and wants to test if the amount of water students drink is related to their endurance level. One week before practice, everyone has a bottle of water. That afternoon, they run the bleachers and record how many times each player go up and back before resting. Next week they do 2 bottles, and the last week a gallon of water. What are the control group, experiment group and Constants?
Control - 1 bottle
Experiment - More than one bottle
Constants - The same exercise, time, etc
600
Explain how the greenhouse effect occurs and how it effects the planet
Light is reflected by the planet's surface, but some of that heat gets reabsorbed by greenhouse gases and stuck in the planet.
600
Name examples of geological processes in the carbon cycle, human activities in the nitrogen cycle, biological processes for the phosphorus cycle and chemical in the water cycle
Carbon - CO2 disolves in the ocean to make carbonates which creates rocks
Nitrogen - humans creating fertilizer releases nitrogen gas
Water - changes various forms (liquid to gas, etc)
Phosphorus - animals eating things rich in phosphorus (primary producers)

A prairie nature reserve is home to a population of pheasants. This year, the population of pheasants has increased sharply, and scientists think the population has exceeded the carrying capacity. The reserve is also home to a small, scattered population of bison. Scientists think that the bison population is significantly below carrying capacity, although it has been increasing gradually from year to year.
Both the pheasant and bison populations of the nature reserve could be affected by a variety of limiting factors. There is a specific limiting factor that effects the both populations the most, which one is it?
Any sort of natural disaster!

White blood cells, called leukocytes, are very different in structure and function than red blood cells. White blood cells help fight infections, parasites, and bacteria. They do this by engulfing pathogens and synthesizing antibodies. Unlike red blood cells, white blood cells can reproduce.
Which organelle, if any, must be present in white blood cells?
Rough ER

A scientist conducted an experiment to determine if the effect of environment can affect fur color of a Himalayan rabbit. The Himalayan rabbit typically has a white coat except for its colder nose, feet, tail, and ears, which are black. The scientist shaved an area of hair on the back of each rabbit, then placed an ice pack over the shaved area on one rabbit (A).
Identify the control group, the independent/dependent variables and what the hypothesis is testing
B and if temperature effects fur color change
