Answer:
a) Because when we exercise, we hydrolyze more ATP to ADP and Pi, and O2 is necessary for the hydrolysis, so we increase our intake of oxygen.
c) Because when we exercise, we produce more CO2 and increased ventilation is necessary to rid ourselves of CO2.
d) Because when we exercise, we use more ATP, and additional O2 is necessary to generate sufficient ATP.
Explanation:
During exercise , our body needs more energy in the form of ATP. This ATP comes from break down of food materials in the mitochondria of the cell during cellular respiration. With the addition of oxygen, more ATP is produced during respiration and this ATP is used by the body. With ATP, carbon dioxide is produced as a waste material which can be removed by exhaled out during breathing.
Answer:
The thoracic duct: It begins near the lower part of the spine and collects lymph from the pelvis, abdomen, and lower chest.
Explanation:
Our interconnected neurons help us process different types of information. Synapses are the gaps between neurons. <span>When an impulse reaches the end of one axon, it is now an action potential. This electric signal cannot leap across this gap so as to speak. Special chemicals called neurotransmitters have this role to be possible. The best answer is thus neurotransmitters. </span>
They have chloroplasts. They do not possess mobility because they cannot just stand up and walk to the nearest river. Unicellular organisms are very small, and most organisms are multi-cellular, including plants. Plants, animals, and fungi are eukaryotic, but only bacteria is prokaryotic. So therefore, choice 3 is correct.
Answer:
its gives us oxygen witch most thing take to stay alive
