Most people recognize biodiversity by species—a group of individual living organisms that can interbreed. Examples of species include blue whales, white-tailed deer, white pine trees, sunflowers, and microscopic bacteria that can't even be seen by the naked eye.
Answer:
B cellular respiration
Explanation:
As mentioned in the question, While running a race, a person's muscles need a constant supply of ATP. This clearly indicate that question is not about a plant but about a human being. Now let us look at the available options:
A) Photosynthesis:
The process of photosynthesis takes place in green plants which is a source for the preparation of glucose or food for them. Moreover, plants just like animals also depend on the process of respiration for the generation of energy in the form of ATP. Therefore, photosynthesis cannot be the right option.
C) Calvin cycle:
Calvin cycle is the process that is also called as dark reaction of photosynthesis. It is second step of photosynthesis which takes place during night when CO2 is used for the preparation of glucose-. Since Calvin cycle is part of photosynthesis, it takes place only in plants and not in humans.
B) Cellular respiration:
Cellular respiration is the key process in which food we eat is broken down through series of reactions to produce energy in the form of ATP. When we do exercise or run fast, our body needs a rapid input of energy to meet the body's energy demands at that moment. Therefore, the rate of cellular respiration increases. This makes cellular respiration right option.
Hope it help!
Throughout our lives all of our bodily systems have cells that duplicate themselves. After a certain number of years, these cells begin to start dying off, or become more prone to mutations that occur in the cell replication process. An example is the eventual death of muscle cells that lead to reduced muscle tone and strength in the elderly. Concerning mutations in cell replication, the more times something happens the more chances there are that something can go wrong. If a cell has replicated itself twenty times, there has been little opportunity for something to go wrong, but when cells have replicated hundreds or thousands of times, pure odds mean the chances are greater for "mistakes". These mutations are what leads to certain diseases that are more greatly associated with aging, such as certain cancers.
