A student rubs identical balloons in the same way with different materials. The student wants to determine the sign and compare the amount of charge on each balloon. Two experimental methods are used. The first is to count the number of identical bits of paper that can be picked up by each balloon. The second is to bring each balloon to the same distance from the top of a positively charged electroscope and observe whether the leaves move together or apart and how much they move. Which of the following correctly indicates what information could be obtained by analyzing the results from each method? a. Number of pieces of paper Motion of leaves
sign and amount of charge sign of charge only

b. Number of pieces of paper Motion of leaves
amount of charge only sign and amount of charge

c. Number of pieces of paper Motion of leaves
amount of charge only sign of charge only

d. Number of pieces of paper Motion of leaves
sign of charge only amount of charge only

both anaerobic and aerobic respiration use glucose (or other carbohydrates), proteins and lipids to produce atp and nadh. cell uses those energy molecules, obtained from food and   breaks them down during the chemical reactions of respiration. in anaerobic respiration, nadh is regenerated to nad+ by enzymes lactate dehydrogenase (lactate is produced, e.g. in muscle cells) or by alcohol dehydrogenase where ethanol is produced (alcohol fermentation), while in aerobic respiration, electrons from nadh are deposited in the mitochondria to regenerate nad+ (electron transport chain. anaerobic respiration produces 2 atp per molecule of glucose compared to aerobic respiration where about 38 atp molecules are produced.

1. a host loses nutrients to a parasite

2. a parasite only benefits when the host is alive (cause if the host dies the parasite dies with it )

3. producers to consumers

4. the tapeworm is a parasite

5. they convert energy from the sun (photosynthesis)

6. sunflower-robin (i think im 80% sure)

7. producer

8. consumer

9. prey

10. fresh water snails ( cause the green algea is the producer and the snails are the primary consumers and the small fish consumer so is the big fish)
