If water runs out then everything dies! :)
Thanks for the opportunity to answer your question and I hope this help! :)
B) the less porous, the less permeable
Porous means "full of holes."
Permeable means "stuff can go through it."
The more porous something is, the more permeable it is.
Answer
Step 1: taken in by plants during photosynthesis.
Step 2: The animal eats a plant and uses it carbohydrates for energy.
Step 3: The animal releases the carbon dioxide back into the atmosphere during respiration.
Step 4: The cycle repeats when the carbon stored in the atmosphere as carbon dioxide gas is taken in.
Hope this helps!
The correct answer is: A) lactic acid.
During the exercise, muscle cells use anaerobic respiration in order to make enough energy in the form of ATP. Anaerobic respiration doesn’t require oxygen, but glucose is broken down to produce energy. Glucose is broken down to pyruvate in the process called glycolysis. Next step is convert of pyruvate into lactic acid (or lactate).
During the exercise, the oxygen level in muscle cells decreases, which results in anaerobic respiration of the cells.
