Spontaneous generation was a (refuted) theory that some forms of life can arise from inorganic matter.
Louis Pasteur refuted it in a series of experiments, in which he boiled different matter (grape juice, broth) which would kill all the bacteria and let it stay for a long time to see if it would develop life (he also had a control condition in which he let the boiled liquid interact with the outside words, and those would develop bacterial life).
Answer: A protein's specific shape determines its function.
Explanation: If the three-dimensional structure of the protein is altered because of a change in the structure of the amino acids, the protein becomes denatured and does not perform its function as expected.
Answer:
Decrease
Explanation:
The carbon footprint is <u>the amount of carbon (in terms of greenhouse gases) being emitted by human activities</u>. In a situation where <u>social distancing is encouraged, human activity would reduce significantly</u>. Very few people will be outside and the causative agents of pollution (anthropogenic) will be significantly reduced. Further, nature would be able to minimize the impacts of pollution when human activities are less than the threshold capacity.
Let's take an example of coronavirus spread globally this year. The social distancing of 2 meters has significantly reduced the number of people going outside. Ultimately, there are fewer automobiles on the roads and a few industries are running. The result is that the air quality index has been significantly improved. For example, in India, people from 300 km away, can see the Himalayan mountain range very clearly (see image attached). This has not happened in decades after modern industrialization.
I’m not sure if that’s the answer but what immediately pops up in my mind is the food chain. Primary consumers (herbivores) consume producers (plants). Secondary consumers consume primary consumers etc. At the end of the day, all kinds of animals die and decompose, providing nutrients for producers to grow, continuing the circle of life.
Lion is a top predator that hunts secondary consumers. Simba’s father died and contribute to the circle of life. I hope it gave you some pointers!
