What is the rigid material in plant cell walls?

How do temperature and salinity affect deepwater currents? question 15 options: as temperatures and salinity levels of water increase, the water rises to the surface where it creates currents as it moves to colder regions. they create changes in wind direction, moving denser water in the same direction as the wind and causing the deepwater circulation patterns found in the ocean. they equalize the forces on undersea currents caused by the coriolis effect as they replace more dense water with less dense water. they create density differences that cause dense deepwater currents to flow toward the equator where they displace less dense, warmer water above them.

Alarge body of air that has similar temperature, humidity and air pressure at a given height is called a

In an experiment, the hypothesis is if the wavelength of the light shining on a plant is shortened, the rate of the photosynthesis is slowed down. this hypothesis testable falsifiable both of the above none of the above
