Which of these statements best describes a similarity between photosynthesis and dissolving in the sea?
Mama L [17]

The correct answer is D. Both absorb carbon dioxide from the atmosphere.

The process of photosynthesis is carried out using atmospheric carbon dioxide by green plants. Many gases including carbon dioxide are dissolved in seawater. Some of the carbon dioxide gas remains in dissolved state but most of the carbon dioxide is reacts with water to form carbonic acid. Dissolved gases in seawater make balance with atmosphere by mixing of the surface by wind and waves. Therefore, both photosynthesis and sea water take carbon dioxide from the atmosphere.

Which part of the brain is associated with ten of the 12 cranial nerves
Luda [366]
Hey there!

There are different types of nerves. Some of them are sensory nerves like the ones in your hands and feet, and some complete other functions. However, they all originate from somewhere.

Cranial nerves originate from the brain itself, and spinal nerves come from the spinal cord. Damaging any can cause serious injury like death and paralysis. There are 12 cranial nerves in the nervous system, and 10 out of 12 originate in the brain stem.

Hope this helps!
