Which option below best explains how animal cells are able to use cellular respiration to carry out cellular functions?

• Food provides energy and water provide oxygen, which is used to break down carbon dioxide for other cellular functions.

• Water molecules found in cell vacuoles are broken down release energy and oxygen which is used for other cellular functions.

• Cellular respiration breaks down stored carbon dioxide found in the body to release oxygen which is then used for cellular functions.

• Breathing provides oxygen and food provides glucose, this combination allows cells to breakdown glucose releasing energy for the cell to carry out other functions.

After playing a soccer match, the girls team “cools down” by slowing down, breathing deeply and eating orange slices. Why does this speed up their recovery process?

• By cooling down in this way they are able to take in carbon dioxide and water which allows their cells to produce energy through cellular respiration.

• By eating a snack they take in energy which converts to sugar needed by the body to produce oxygen the athletes muscles to begin cellular respiration.

• By breathing deeply they release more carbon dioxide which leads to more energy for cellular respiration to begin.

• By cooling down in this way they are able to take in oxygen and sugar which allows their cells to produce energy through cellular respiration.

Which statement below best explains why cellular respiration is important to living organisms?

• It is the process by which living organisms use energy from the sun and water to create food in the form of sugar.

• It is the process by which living organisms take in oxygen and water to create food in the form of sugars and energy.

• It is the process by which living organisms break down sugar from food to combine with oxygen making usable energy.

• It is the process by which living organisms take in oxygen and release carbon dioxide through the cells thereby providing energy.

How does the process of photosynthesis provide evidence for the Law of Conservation of Mass?

• The total mass of glucose created at the end of photosynthesis equals the amount of carbon dioxide used.

• In photosynthesis the total amount of glucose and oxygen produced will equal the total amount of water and carbon dioxide initially used.

• In photosynthesis the total mass is equal to the amount of carbon dioxide and water used to produce energy and oxygen.

• The total mass will not change in photosynthesis since equal amounts of oxygen and water are produced when equal amounts of energy and carbon dioxide used.

Imagine you have a sealed jar containing three bean seeds, air, and a moist paper towel. Nothing can get in or out of the jar. The total mass of the jar and its contents is 100 grams. Imagine the same jar with its contents 12 days later. During that time the jar remained sealed. Nothing could get in or out of the jar. The seeds have germinated to form 6 centimeter seedlings. The total mass of the jar and its contents after the 12 days is recorded. What is outcome?

• There will be no change in the total mass of the jar with the seedlings after 12 days

• The total mass of the original jar with seeds will be less than total mass of the jar with the seedlings.

• The total mass of the original jar with seeds will be more than the total mass of the jar with the seedlings.

Which of the following is the correct equation for PHOTOSYNTHESIS?

• CO₂ + light + H₂O --> O₂ + Sugar
• CO₂ + sugar + H₂O --> O₂ + light
• _O2 + light + H₂O --> CO₂ + Sugar
• CO₂ + O₂ + H₂O --> Light+ Sugar

Which of the following options best explains how a lack of chlorophyll would affect the process of photosynthesis in plants?

• A lack of chlorophyll will trigger plants to increase the rate of photosynthesis in order to increase production of food.

• A lack of chlorophyll will limit the amount water plants are able to take in, resulting in a slower rate of photosynthesis.

• A lack of chlorophyll would increase the production of oxygen because the plant would need to work hard to feed themselves.

• A lack of chlorophyll would limit the amount of light absorbed by the plant and hinder the amount of food the plant is able to produce for itself.
