This organelle is the control center of the cell

The nucleus

What are the 3 molecules that our bodies use for energy?

Fats (fatty acids), proteins (amino acids), carbohydrates (glucose)
100

List 3 density-independent factors

Natural disaster, weather changes, habitat loss

200

What is amplitude?

The height of a wave

200

What is a chemical reaction?

When substances react to produce products with different properties than the reactants.

200

This is the powerhouse of the cell. It breaks down glucose for energy.

Mitochondria

200

What is the equation of cellular respiration?

Food (glucose) + Oxygen --> Carbon Dioxide + Water + Energy

200

What does biodiversity mean?

The amount of species in a given area

300

How is a sound produced?

Using vibrations.

300

Why is it important to know the properties of substances?

Properties allow unknown substances to be identified. They also give scientists an idea of how substances will behave under certain conditions.

Animals don't have this organelle. It's purpose is to protect the plant and provide it structure.

Cell wall

300

Describe the process of gas exchange.

Oxygen passes from the alveoli to the blood and carbon dioxide passes from the blood into the alveoli.

300

Which type of farming decreases the spread of plant diseases?

Diversified farming

400

How does a one-way mirror work?

50% reflection, 50% transmission

400

Name 3 property tests.

Flammability, density, melting point, boiling point

The largest organelle in plant cells. It stores food, water, metabolic and toxic wastes.

Vacuole

400

What type of blood vessels deliver nutrients to cells?

Capillaries

Why are Sea Otters Keystone Species?

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?

Infrared

What are the 4 signs of a chemical reaction?

Light released, color change, gas produced, formation of a precipitate

500

Small organelles that make proteins.

Ribosomes

500

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.
