This goes back to Darwin's theory of Evolution. This why certain animals are different colors. This is to protect them from natural predators so the population stays high or also why giraffes have long necks so they can reach food up on trees.
1. because almost all medical remedies rely on plants
2. it makes plants grow and we are able to manipulate the light to effect the photosynthesis that it under goes to make new medicine
3. with different types of photosynthesis the pigments change and allows others to be able to take that medicine because that link is not longer there to be damaging to the body<span />
Answer:
Functions of the circulatory, respiratory, and nervous system in gas exchange are interconnected with each other in the following manner:
The circulatory system is responsible to pumps blood around the body. The circulation system allows the absorption of oxygen and releases carbon dioxide in the lungs and the Respiratory system also take oxygen in and releases carbon dioxide. The circulatory system and respiratory system work hand in hand. The brain or nervous system monitors gas or oxygen level in blood and regulates respiratory rate.
Human activities contribute to climate change by causing changes in Earth's atmosphere in the amounts of greenhouse gases, aerosols (small particles), and cloudiness. The largest known contribution comes from the burning of fossil fuels, which releases carbon dioxide gas to the atmosphere.
The water cycle and the oxygen cycle
