How do proteins play an important role in the mating of Japanese beetles?
By sending and detecting chemical messages
Which describes how proteins are used in mating by Japanese beetles?
Males use a protein to detect pheromones sent by females.
How are proteins used in mating by Japanese beetles?
They send proteins as chemical messages.
Which structure is found in all cells?

Rough endoplasmic reticulum
Which organelle is covered in ribosomes?
Rough endoplasmic reticulum
Which best describes a difference between prokaryotic cells and eukaryotic cells?
Eukaryotic cells contain organelles that are enclosed in membranes.
What do eukaryotic cells have that prokaryotic cells do not?
Membrane-enclosed organelles
Which observation proves that a cell is a eukaryote?
It has enclosed organelles inside the cell.
Which observation proves that a cell is a eukaryote?
It has DNA inside a nucleus.
Which observation proves that a cell is a eukaryote?
The cell contains a nucleus.
What would most likely happen if green plants were exposed to longer days of sunlight?
The chloroplasts would produce more energy.
What would most likely happen if green plants were exposed to less sunlight?
The chloroplasts would produce less energy.
A green plant receives more sunlight than usual. Which part of the plant cell would be most directly affected by this change?
Chloroplasts
Which organelle is responsible for garbage disposal and recycling in an animal cell?
Lysosome
Which organelle sorts proteins so they can be used by the body?
The Golgi apparatus
Which organelle packages proteins in vesicles and sends them to the body where they are needed?
Golgi apparatus
A scientist investigates two types of cells located in different parts in the human body. Cell A contains many more mitochondria than Cell B. What is the best conclusion to make from this observation?
Cell A does more work than Cell B.
