When you are sick, this system works with the circulatory system to deliver white blood cells to fight off infections. What is it?
What is the immune system?
What is the function of an enzyme? (Hint: Use catalyze in your response)
To catalyze (speed) up chemical reactions, they do this by lowering activation energy

What are the reactants of photosynthesis?
What is the difference between a community and a population?
A community is different species interacting with one another while a population is the same specie interacting with one another
The ________ system is responsible for movement while the __________ system is responsible for protection and support
Muscular system = move
Skeletal system = protection
Gene expression can result in the production of certain biomolecules by the body's organelles. Which biomolecule is involved with the process pictured below:
To carry out photosynthesis, plants need to carry water into their leaves. Identify the two plant systems that help plants get water and transport it to their leaves. Describe how they accomplish this task.
Root System = Absorbs water
Shoot system = Transports water from the roots up to the leaves
A bee gathers nectar from a flower and accidentally rubs some pollen on its fussy body. As the bee travels to another flower, the pollen is distributed and plant reproduction occurs.
What type of symbiotic relationship is happening here? (Mutualism, commensalism, parasitism, or predation)
Mutualism since the flower benefits and the bee also benefits!
This system is responsible for the creation of gamete cells that are involved in meiosis
What is the reproductive system?
How does cross-pollination help plants? What mechanism of evolution is this? (Gene Flow, Bottleneck, Founder Effect, Mutation, or Natural Selection)

You are transferring genes/alleles between different organisms. Helps plants reproduce. Gene Flow.
When there is too much water in a plant, the stomata will open in order to allow some water to exit and for gas exchange to occur. What type of feedback mechanism is this? (Positive or Negative Feedback Loop). Explain why.
Negative feedback loop. Bringing the organism back to normal levels.
In the bottle below, there is a high concentration of carbon dioxide. How would adding plants reduce the concentration of carbon dioxide?

Plants absorb carbon dioxide, so there would be less carbon dioxide in the bottle after and you would see the balloon deflate.
The excretory system is responsible for filtering waste out of our bodies. Sometimes, it has to filter waste AGAINST a concentration gradient and needs to use ATP.
What type of transport does excretory system use?
Active Transport
Why is the image below important/what process does it show?

Crossing Over (increases genetic variation)
What are the products of the organism shown below?
In the food web below, what are the trophic levels of the fox?

The fox is a secondary consumer and tertiary consumer
There are two types of viruses. A scientist is trying to find out which type of virus he is currently investigating. These are the traits of the virus:
1. Incubation Time: 4 hours
2. Symptoms: Shortly after exposure
3. Structure: Capsid coat with glycoproteins surrounding it. Bursts the cell immediately after exposure.
What virus is the scientist investigating?
Lytic virus
Turtles hatch specific genders at certain temperatures. Why?

Gene Expression (environment can control what genes are activated)
What are the male and female parts of the plant image listed below?

Male: Stamen (anther, filament) that makes pollen
Female: Stigma, pistil and ovaries where the eggs are made to make seeds
What type of bacteria convert nitrogen gas into a usable form by plants? Through what process are they absorbed by plants?

Assimilation is how they are incorporated into plants
