Coleus is a type of plant that has many variations in its leaves. Many coleus plants have chloroplast-rich areas on the edge of the leaf. Other areas in the middle lack chloroplasts. A student exposed the coleus leaf to sunlight. Later, starch indicator was added to the entire leaf. The diagram below shows the result of the experiment.
Which statement is a valid claim, supported by evidence from this experiment?
Chloroplasts are necessary for the production of starch indicator
Starch indicator causes leaves to produce oxygen.
Chloroplasts are necessary for the production of starch.
Water is necessary for the production of starch.

The cells of some organisms contain both chloroplasts and mitochondria. Which statement describes what would happen in these cells if they were moved from a light environment to a dark one?
The amount of oxygen present would decrease and the amount of carbon dioxide would increase.
The amount of glucose present would increase and ATP would no longer be available.
The amount of carbon dioxide present would decrease and ATP would continue to be synthesized.
The amount of oxygen present would increase and the amount of glucose available would decrease.
An ecosystem is represented below. The organisms represented as algae and seaweed are found in the area shown due to which factor?
pH
sediment
light intensity
colder temperature
Which statement concerning this process is correct?
The process represented is respiration and the primary source of energy for the process is the Sun.
The process represented is photosynthesis and the primary source of energy for the process is the Sun.
This process converts energy in organic compounds into solar energy which is released into the atmosphere.
This process uses solar energy to convert oxygen into carbon dioxide.
The graph below shows the results of an experiment in which a container of oxygen-using bacteria and strands of a green algae were exposed to light of different colors.

Living organisms must be able to obtain materials, change the materials into new forms, remove poisons, and move needed material from one place to another. Many of these activities directly require
energy released from ATP
carbohydrates formed from receptor molecules
the synthesis of DNA
the breakdown of energy-rich inorganic molecules
To remain healthy, organisms must be able to obtain materials, change the materials, move the materials around, and get rid of waste. These activities directly require
energy from ATP
