Some photosynthetic organisms contain chloroplasts that lack photosystem ii, yet are able to survive. the best
way to detect the lack of photosystem ii in these organisms would be
a) to determine if they have thylakoids in the chloroplasts.
b) to test for liberation of o2 in the light.
c) to test for co2 fixation in the dark.
d) to do experiments to generate an action spectrum.
e) to test for production of either sucrose or starch.

Darrel conducted an experiment with the following procedure: fill two cups with ice water. place an uninflated balloon snuggly onto your left index finger. blow a little air into an identical balloon, and place it onto your right index finger. place both fingers into the cups of ice water. darrel noticed that his right finger felt warmer in the ice water than did his left finger. which of the following does the experiment show? a. air is a good radiator of heat. b. air is a good insulator of heat. c. air is a good conductor of heat. d. air is a good convector of heat.

Cassandra made a venn diagram to compare and contrast the two stages of cellular respiration. which belongs in the area marked x? energy is released. oxygen is used up. glucose is broken down. carbon dioxide is used up.

The negative impacts of nonnative species generally outweigh the positive impacts
