Stomata close is the best option
Answer:
Light refracts whenever it travels at an angle into a substance with a different refractive index (optical density). This change of direction is caused by a change in speed. When light travels from air into water, it slows down, causing it to change direction slightly. This change of direction is called refraction
Hope this helps.
To find the density of an object, divide the mass by the volume. To find the density of the object in your problem, use a calculator to divide 60.0 by 400.0
Answer:
C. To confirm that the alternative fuel is cleaner than fuels currently used
Explanation:
The current fuels from mining, cutting down trees and even transportation is bad for the atmosphere. These fuels cause climate change which could potentially bring a lot of dangers. The reason scientists would conduct research on a newly alternative fuel is so that the fuel would be a lot more cleaner which could prevent the dangers that are to come.
