Answer:
Carbon dioxide is a gas which is released in the atmosphere as greenhouse gas, burning of fossil fuel, released in respiration process. Rise in the levels of carbon dioxide and other gases has resulted in increase in global temperatures. Increase in carbon dioxide and temperatures are responsible for weather fluctuations and global warming.
Weather fluctuation means untolerated heat and lack of precipitation or rain. Weather fluctuations will affect seasons. Seasons are necessary for maintaining the life cycle of organisms. Inappropriate seasons due to climatic change will affect the life of living organisms.
Global warming is an issue which is mainly due to release of hot heat trapping gases from green house and other sources, increasing the atmospheric temperature. This will result in melting of ice from glaciers in world. The inhabiting animals living in the glaciers will suffer a lot from this as they cannot tolerate warm climatic conditions.
Perception of pitch and sound intensity is the cocklear
Answer:
I believe the answer to this question is b observable physical evidence.
Explanation:
The reason for this is because scientists make predictions and use evidence to back up their hypothesis. If the evidence doesn't support their claim, they make up a new one, until they have gathered enough evidence to support their claim. This can be done through past knowledge, like failures and successes and lab experiments, so it is not only each of them, so the answer cannot be c or d. Out of the two options, a and b, I just thought about it and picked b as the reasonable answer. Please give me feedback on the answer, if it is right or not. Thanks! Hope I helped!
The answer should be agriculture.
Agriculture means farming of crops or the rearing of animals, either for their own use or for commercial purposes. Rural area means a place away from the city, opposite of urban areas, with little buildings and most likely have a smaller population.
On the other hand, construction and manufacturing most likely is going to be common in urban area, as urban area is more likely to have more buildings being built and most of the products are made in the factories in urban areas. Therefore, the only activity that is almost practiced exclusively in rural area is agriculture. Urban areas don't have much space and well environment for agriculture activities.
Agriculture activities can be energy consuming as some may require different machines to help with farming processes such as harvesting or irrigation.
