Microplastics are small pieces of plastic that measure 5mm or less in size that can be harmful to ocean and aquatic life. Which statement best describes why environmental monitoring of microplastics needs to be performed?
A. To evaluate the levels of other pollutants in the water
B. To determine the ways microplastics can impact an ecosystem
C. To ensure all plastics are banned before they impact public health
D. To compare the water quality of this ecosystem to another ecosystem
B. To determine the ways microplastics can impact an ecosystem

What reactant(s) are used in anaerobic cellular respiration?
Glucose
200
Which of the following processes is part of the carbon cycle?
A. Decomposers put carbon into the soil by breaking down organic material.
B. Factories remove carbon from the atmosphere by burning materials.
C. Plants put carbon back into the atmosphere through the process of photosynthesis.
D. Animals remove carbon from the atmosphere through the process of respiration
A. Decomposers put carbon into the soil by breaking down organic material.

How does biomagnification affect an ecosystem?
As toxins move up the food chain, they can harm each level. This can lead to a decrease in populations and eventually biodiversity loss.

Identify the function(s) of the macromolecule illustrated below
1. Long-term energy
2. Compose cell membranes
300
This organelle is necessary for all types: It is responsible for synthesizing proteins
Ribosome

Local environmentalists have noticed that a bird population has decreased in a local forest. They think that pollution from the nearby chemical plant is to blame. After pressure from the community, the factories put filters over their smokestacks to trap pollution before it is released into the air. Why would city officials need to monitor the bird population after the factories solved the issue?
To make sure the pollution from the chemical plant was causing the harm to the bird popoulation
400
Nitrogen is an element that helps which macromolecule function in the transport of molecules across the cell membrane?
Proteins
400
This organelle is located closely to the ER and is responsible for modifying and transporting proteins to different parts of the cell/body
Golgi apparatus

Which of the following is an environmental cost of using renewable resources?
A. Low greenhouse gas emissions.low greenhouse gas emissions. - no response given
B. Resources are replaceable by healthy ecosystems
C. Lower energy output than nonrenewable resources
D. Takes up an ecological footprint that destroys habitats
D. Takes up an ecological footprint that destroys habitats

A community is considering a proposal to build a new housing development that would convert a large area of native forest into residential lots. The proposal includes a plan to plant non-native ornamental trees and shrubs throughout the development. What would be the long-term environmental impact of this project on the local ecosystem? (Think of the impact of non-native species)
The replacement of native species with non-native plants and the loss of forest habitat will lead to a decrease in biodiversity and a disruption of local food webs

Lipase is an enzyme found in the human digestive tract that breaks down lipids into glycerol. Which of the following would tell you that Lipase is functioning optimally?
A. The most amount of glycerol in the body
B. The most amount of lipids in the body
C. An equal concentration of lipids and glycerol
D. The most amount if lipase in the body
A. The most amount of glycerol in the body
