Larry was told that a certain muscle cream was the newest best thing on the market and claims to double a person's muscle power when used as part of a

muscle-building workout. Interested in this product, he buys the special muscle cream and recruits

Patrick and SpongeBob to help him with an experiment. Larry develops a special marshmallow

weight-lifting program for Patrick and SpongeBob. He meets with them once every day for a

period of 2 weeks and keeps track of their results. Before each session Patrick's arms and back are

lathered in the muscle cream, while Sponge Bob's arms and back are lathered with the regular

lotion.

10.Which person is in the control group?

11. What is the independent variable?

12.What is the dependent variable?

13. What should Larry's conclusion be?

answer: - few nutrients

high pressure

low temperatures

explanation: 1. few nutrients:   open-ocean zone is located way far from the land, which is the main source of the essential nutrients.2. high pressure: pressure increases by 1 atmosphere for every 10 meters increase in depth.3. ample sunlight: a large fraction of the sunlight is reflected back to the atmosphere from the sea surface. 4. varying salinity: below the thermocline, the water is isolated from the atmosphere so the salinity remains stable over the year.5. low temperatures:   the temperature of open-ocean zone ranges from a low of -2°c to an average of 17°c

one part of the electromagnetic spectrum that arrives on earth as solar radiation from the sun is the visible spectrum. wavelengths of the visible spectrum combine to form what we refer to as

answer - d) ultraviolet radiation.

violet /   380–450 nm / 668–789 thz
