​SCIENCE 8 REVIEW

Multiple Choice

After running around Jellyfish Fields all day, SpongeBob starts breathing faster to supply more oxygen to his body. Which two characteristics of life are mainly shown?

• growth and nutrition

• reproduction and excretion

• sensitivity and excretion

• movement and respiration

Multiple Choice

Plankton creates thousands of clones of himself to take over the Krusty Krab. What characteristic of life would this ability represent?

• growth

• reproduction

• sensitivity

• movement

Multiple Choice

SpongeBob and Squidward decided to compete to see who could eat more Krabby Patties. As they eat, their bodies break down the food to release energy and later remove the excess fats through waste. Which sequence of life processes occurs in this situation?

• nutrition → respiration → excretion

• respiration → growth → reproduction

• excretion → movement → sensitivity

• growth → nutrition → sensitivity

It is SpongeBob's first day of school and he was given an assignment about the different levels of organization. Help him in his homework!

Open Ended

SpongeBob was asked to arrange the levels of biological organization. He arrived with this answer:

Organs → Cells → Tissues → Organ systems → Organism

Do you think his answer is correct?

Multiple Choice

Patrick helped SpongeBob examine a small piece of jellyfish muscle under a microscope. He sees many similar cells lined up and contracting together. What level of organization is he observing?

• Tissue

• Cells

• Organism

• Organ

Multiple Choice

SpongeBob wrote in his notebook:

“If one type of cell stops working properly, the tissue and the organ it belongs to might also fail.”

What scientific reasoning best supports SpongeBob’s statement?

• Cells function independently from each other.

• Organs and tissues work together in a body.

• Cells can be considered as an organism.

• Each level of organization relies on the proper function of the previous one.
