What is a producer/autotroph?

• an organism that gets energy from eating other organisms

• an organisms that uses sunlight to make its own food

• an organism that gets energy from eating dead organisms, non-living material or waste

• an organism that uses chemical energy to make its own food

What will most likely be the result if all of the mitochondria are removed from a plant cell? 

• It will be unable to carry out respiration. 
• It will lose water through osmosis.  
• It will break down ribosomes in the cell
• It will be unable to photosynthesize.

What is the function of autotrophs in the carbon cycle?

• to use oxygen to produce glucose 
• to take in excess water
• to use carbon dioxide to produce glucose
• to feed on herbivores 

Two different populations of birds live in the same area and eat the same types of food. Which most likely describes the relationship between these two populations of birds? 

• competition
• mutualism
• parasitism
• predator-prey

Which statement best describes the relationship that exists among proteins, DNA, and cells?

• Proteins combine to produce cells, which produce DNA
• Proteins are made up of DNA, which determines the cells that are produced. 
• DNA is made up of proteins, which tell a cell how to function. 
• Cells contain DNA, which controls the production of proteins.

Why is meiosis important for sexual reproduction?

• It allows the zygote formed from fertilization to have triple the chromosome number of the organism. 
• It allows gametes to have twice the original number of chromosomes of the organism.
• It allows gametes to have half the original number of chromosomes of the organism. 
• It allows the zygote formed from fertilization to have half the original number of chromosomes of the organism.

A freshwater plant is placed in a container of saltwater. What will most likely happen to the cells of the plant?

• They will swell because water will move into them.
• They will swell because salt will move into them
• They will shrink because water will move out of them.
• They will shrink because salt will move out of them.

How does the amount of energy resulting from fermentation compare with that of aerobic respiration? 

• Aerobic respiration results in less energy.
• Aerobic respiration results in more energy.
• Each process results in equal amounts of energy.
• Each process results in variable amounts of energy.

Which best explains why muscle cells are different from blood cells? 

• A mutation occurs during the development of muscle cells but not in blood cells.
• Different genes are activated in muscle cells than in blood cells. 
• Muscles cells experience different environmental influences than blood cells. 
• Muscle cells are produced by the brain, but blood cells are produced by the heart.
