Answer:
The digestive system is responsible for taking whole foods and turning them into energy and nutrients to allow the body to function, grow, and repair itself.
Explanation:
Answer:
1) If a pesticide was used to kill the grasshoppers and the caterpillars, then the frogs should be fine, because the pesticide isn't made to effect them; also, unless their diet was only of grasshoppers and caterpillars, then the frogs would not starve.
2) Two human activities that can impact the ecosystem are, pollution, and deforestation. Pollution, because it can harm animals, but against popular (but unscientific) belief, doesn't cause climate change. Deforestation also harms animals, and also causes for some trees to have to produce more oxygen than before.
3)Life on earth could not exist on earth without plants and decomposers because there would be no oxygen left on earth for creatures to breathe, and there would be no nutrients to keep the earth alive.
Answer:
The correct answer is C. They are found on the end of bronchioles.
Explanation:
Alveoli are the sac-like structures that are formed by the terminal bronchioles so alveoli are the terminal structures through which many air sacs are raised called alveoli which helps in the transport and exchange of CO₂ and O₂ between lungs and blood.
Blood capillaries surround each alveolus and carbon dioxide moves from blood present in these capillaries to alveoli because the partial pressure of carbon dioxide is higher in blood capillaries than in alveoli and oxygen moves from alveoli to blood because the partial pressure of oxygen is higher in alveoli than blood.
Therefore the correct answer is C. They are found on the end of bronchioles.
