<span>Velocities are vectors so we can add them!

Let's let +x be East and -x be West.

 -0.9 + 2.7 = 1.8
 
Since our answer is positive that means East so the answer is C.</span>

How does the physical structure of a plant have<br> Large leaves help it survive?
elena-14-01-66 [18.8K]

The large leaves help it survive as they serve as the<u> organ for photosynthesis.</u>

Explanation:

  • Photosynthesis, the process by which green plants and certain other organisms transform light energy into chemical energy.
  • During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds
  • Leaves provide food and air to help a plant stay healthy and grow. Through photosynthesis, leaves turn light energy into food.
  • Through pores, or stomata, leaves breathe in carbon dioxide and breathe out oxygen. Leaves also release excess water.
  • Most leaves are broad and so have a large surface area allowing them to absorb more light
  • A thin shape means a short distance for carbon dioxide to diffuse in and oxygen to diffuse out easily.
  • The exchange of oxygen and carbon dioxide in the leaf occurs through pores called stomata.
  • Normally stomata open when the light strikes the leaf in the morning and close during the night.
