What is the equation of cellular respiration?
Food (glucose) + Oxygen --> Carbon Dioxide + Water + Energy
What does biodiversity mean?
The amount of species in a given area
How is a sound produced?

Vacuole
What type of blood vessels deliver nutrients to cells?
Capillaries
They limit the number of sea urchins in the ecosystem. With less sea urchins, more kelp can remain. The kelp is a main resource for many aquatic AND land animals. Without kelp, most animals will not survive in the ecosystem.
What type of electromagnetic radiation does a TV remote use?

Small organelles that make proteins.
Ribosomes
Describe the process of how blood flows to the lungs and throughout the body.
Arteries bring oxygen poor blood to the lungs. Capillaries pick up oxygen at the alveoli. Veins bring oxygen-rich blood back to the heart. Arteries bring oxygen-rich blood to the rest of the body. Capillaries deliver it to cells. Veins carry oxygen-poor blood back to heart.
