Skeletal muscles can use both aerobic and anaerobic respiration to produce the atp needed for muscle contractions. skeletal muscles can also stockpile a small amount of atp and another molecule, phosphocreatine (pcr), that can be used to convert adp into atp quickly without having to use either form of respiration. in prolonged exercise, such as swimming, all three of these processes are used to supply atp for muscle contraction. what is the correct order in which processes are used in the muscle cells during a prolonged swim?

humans are now responsible for causing changes in the environment that hurt animals and plant species. we take up more space on earth for our homes and cities. we pollute habitats. human activity often changes or destroys the habitats that plants and animals need to survive.

sorry to break it to ya but no one can answer your question it's just

jk but i am serious about the part that most people cant answer it beacuse you did not mention the section you are talking about. but it would if you added some detail and were a bit more specific.
