Identify a structure other than a cell wall or a vacuole that might be found in a plant cell but not in an animal cell. explain
enot [183]
One structure that can be found is most plant cells is chloroplast. A plant cell may have around 0 to 20 chloroplast, depending on their location in plant or their function.

Chloroplast is the structure that photosynthesis occurs. Photosynthesis is the method that plant make food for themselves. They turn sunlight into food such as starch.

Plants are autotrophs, which means they make food themselves, they don't need food from other sources like animals. Therefore, chloroplast is not found in animal cells because we are heterotrophs, we feed on other food.

Will earth run out of water?
Kazeer [188]

<u>While our globe may never run out of water as a whole</u>, it's crucial to realize that pure freshwater isn't always available where and when humans require it. In fact, only six countries contain half of the world's freshwater. Over a billion people do not have access to adequate safe, clean water. Water scarcity will afflict the entire planet by 2040 unless water use is significantly decreased. "If we keep doing what we're doing now, there will be no water by 2040."

Acid rain is caused by a chemical reaction that begins when compounds like sulfur dioxide and nitrogen oxides are released into the air.
