the birds either starve or adapt to their new circumstances
Anaerobic organisms, those which do not perform the standard 'cellular respiration' or 'photosynthesis', do not require oxygen, nor sunlight to survive. Instead, they survive off of glycolysis which is a process also carried out in aerobic respirators, but it is one that does not <em>require </em>oxygen or sunlight. You can do this by using lactate, sulfate or even alcohol instead of the usual oxygen.
The medulla oblongata is the part of the brain stem that regulates the bodily processes that are automatically regulated such as respiration and blood pressure. During respiration process, the medulla oblongata functions by detecting the level of carbon dioxide and oxygen in the blood stream and sending necessary signals in form of nerve impulses to the heart muscles and diaphragm for necessary actions. This shows that the respiratory system and the circulatory system work together and that is the reason why heart rate and breathing rate are both controlled by medulla oblongata.
Answer:
The oil produced in United States is light and low sulfur content and they do not have proper processing facilities, hence purchase it from other countries.
Explanation:
About 9.93 million barrels per day U.S purchase oil from 86 countries. Because the crude oil present is not homogeneous in nature. It is very light in nature with low sulfur content or may be high,this particular factor depends upon the method of the refining. Most of the oil are being exported by the Saudi Arabia and then comes Russia followed by Iraq. Despite the collapse in price, U.S. dependence on foreign oil should continue to decrease.
Answer:Limiting factors can be both.
Explanation: Biotic limiting factors can be the amount of food in the area, mates, and competition for other resources. But they can also be abiotic due to tempature, natural, disasters, sunlight and stuff like that.
