What can the scientists learn about living things from their samples?
Living things must be made of multiple cells
Living things must be seen with the naked eye.
Living things can only be seen under a microscope
Living things can be made of one or many cells.
Select TWO things that euglena and cells from Anacharis have in common.
Both have multiple organelles
Both have an eye spot to detect light.
Both have structures to help them move.
Both use the Sun's energy in photosynthesis.
Both produce carbon dioxide and food for organisms.
Escherichia coli, also call E. coli is a bacteria that is too small to be seen with the naked eye. Many strains of the bacteria are found in the intestines of humans and animals. Most of the strains are harmless, and some of the strains are helpful because they aid in digestion. A few of the strains found in some foods are dangerous and can make a person sick if they are eaten. Except for extreme heat, E. coli bacteria can survive in many conditions.
Which argument BEST supports a claim that bacteria can be harmful?
E. coli can be found in the intestines of humans and animals
E. coli bacteria are very small and can only be observed using a high powered microscope.
E. coli bacteria break down food in the intestines of humans and animals and take away their nutrients
E. coli bacteria can make a person sick if they eat food that has not been cooked at a high temperature.
Which statement BEST compares the outer layers of plant cells and animals cells?
Plant cells have one outer layer, while animal cells have two outer layers
Plant cells have two outer layers, while animal cells have one layer.
Plant cells have two outer layers, while animal cells have three outer layers.
Plant cells have three outer layers, while animal cells have two outer layers.
Which statement BEST describes how microorganisms decomposers are beneficial to the environment?
They create more organic matter.
They destroy harmful organisms.
They help in the breaking down of organic matter.
They remove carbon dioxide from the atmosphere.
Which statement is supported by evidence from the experiment?
The organic matter reduced the most when a small amount of decomposers were added to the enclosed area.
The organic matter reduced the least when a large amount of decomposers were added to the enclosed area.
The organic matter reduced the least when a small amount of decomposers were added to the enclosed area.
The organic matter reduced the most when a large amount of decomposers were added to the enclosed area.
What can be concluded about the decomposers in the experiment?
The decomposers are microorganisms that help break down organic matter.
The decomposers are microorganisms that add more organic matter to the area.
The decomposers are microorganisms that have no effect in breaking down organic matter.
The decomposers are microorganisms that transport organic matter from one place to another.

Which argument MOST likely describes the effect of an algal bloom on an ecosystem?
The temperature of the water will increase the number of food sources for marine life.
Plants in the water will not receive enough sunlight and their population will decrease.
The temperature of the water will become too cold for marine life to be able to survive.
Plants in the water will receive extra nutrients from sunlight and their population will increase.
