1. What is some information about Cellular Respiration?
2. What is some information about Photosynthesis?
3. What are the connections between Photosynthesis and Cellular Respiration?
Answer:
1.cellular respiration, the process by which organisms combine oxygen with foodstuff molecules, diverting the chemical energy in these substances into life-sustaining activities and discarding, as waste products, carbon dioxide and water.
2.
Explanation:
Green leaves synthesize food woth the help of air, sunlight and water by a process called photosynthesis
3.Photosynthesis converts carbon dioxide and water into oxygen and glucose. Glucose is used as food by the plant and oxygen is a by-product. Cellular respiration converts oxygen and glucose into water and carbon dioxide.
THIS FOLLOWING ANSWER IS ONLY FOR QUESTION ONE:
Cellular respiration is what cells do to break up sugars to get vitality they can utilize. Cellular respiration takes in food and employments it to create ATP, a chemical which the cell employments for energy. More often than not, this process uses oxygen, and is called aerobic respiration. It has four stages known as glycolysis, Link reaction, the Krebs cycle, and the electron transport chain. This produces ATP which supplies the vitality that cells have to be compelled to do work. When they do not get sufficient oxygen, the cells use anaerobic respiration, doesn’t require oxygen. In any case, this process produces lactic acid, and isn't as productive as when oxygen is utilized.
Aerobic breath, the method that does utilize oxygen, produces much more energy and doesn’t create lactic acid. It too produces carbon dioxide as a squander item, which at that point enters the circulatory system. The carbon dioxide is taken to the lungs, where it is traded for oxygen. The rearranged equation for aerobic cellular respiration is:
[tex]C6H12O6 + 6O2 = 6CO2 + 6H2O + Energy (as ATP)[/tex]

Bats hunt using echolocation, in which they send and receive high frequency sounds to locate prey. When bats hear the sounds of others, they typically begin hunting in the same area. As the number of bats hunting in the area increases, individuals become more successful at locating and capturing prey. Some populations of bats live in areas with high levels of noise pollution, such as near heavily trafficked bridges. How might the hunting behavior of bats be affected by such an environment? A. Bats would be more likely to hunt in groups, so an individual's success in catching prey would increase. B. Bats would be better able to use echolocation, which would improve their ability to find prey. C. Bats would be unable to use echolocation, which would prevent them from finding any prey. D. Bats would be less likely to hunt in groups, so an individual's success in catching prey would decrease.
Answer: C) Bats would be unable to use echolocation which would prevent them from finding any prey.
Explanation: I believe it’s B because if there is a long of noise pollution it would interfere with there echolocation causing them to not be able to find prey.
Answer:
C. Bats would be unable to use echolocation which would prevent them from finding any prey.

The major environmental change that is occurring today that could cause the next mass extinction is climate change, which is the last option as climate change is the major environmental change.
What is climate change?Climate change is caused by the increase of greenhouse gases in the atmosphere, primarily carbon dioxide from burning fossil fuels. This increase in greenhouse gases leads to global warming, which in turn causes changes in temperature and weather patterns around the world. These changes have significant impacts on ecosystems and can lead to the extinction of many species. Climate change can cause more frequent and severe extreme weather events such as droughts, floods, and hurricanes.
Hence, the major environmental change that is occurring today that could cause the next mass extinction is climate change, which is the last option as climate change is the major environmental change.
