Answer:
1.In biology, evolution is the change in the characteristics of a species over several generations and relies on the process of natural selection. The theory of evolution is based on the idea that all species? are related and gradually change over time.
2.Survival of the fittest is a simple way of describing how evolution (the process by which gradual genetic change occurs over time to a group of living things) works. It describes the mechanism of natural selection by explaining how the best-adapted individuals are better suited to their environment.
Cellular respiration and photosynthesis are essential to the carbon cycle because cellular respiration involves the intake of oxygen o2 and the exhale of carbon-dioxide co2 into the atmosphere. Where photosynthesis uses the carbon dioxide and water to create oxygen and sugars through energy to repeat the cycle. Respiration in general is a process where carbohydrates are turned into dihydrogen monoxide or water and co2(carbon dioxide). Living organisms together throughout the biosphere and atmosphere work together to continue this because carbon itself is an organic substance.
The conditioned reinforcers known as tokens can be accumulated and traded for different reinforcers.
Any two suitable examples, such as a compliment, an invitation to dinner, the presence of a loved one, or a warm greeting are all suitable examples. These are all conditioned reinforcers since they are connected to stronger reinforcers. They cannot be accumulated and swapped for different backup reinforcers, hence they cannot be considered tokens.
What is backup reinforcer?
Backup reinforce is a reinforcer that serves as the foundation for a conditioned reinforcer. It is a reinforcer in a token system for which tokens can be traded in order to keep their reinforcing properties. For instance, poker chips can be converted into cash at the conclusion of a game of poker. The money serves as a secondary reinforcer in this situation. It is allowed to use any two relevant examples.

Answer:
The answer is B. It is an endothermic reaction.
Explanation:
Photosynthesis in an endothermic reaction. Endothermic reactions are all those chemical reactions that in their transformation process, in 2 or more different substances, consume Caloric Energy, in which, the products obtained possess higher energy levels, than the initial reagents, since they have taken part of the heat of the environment.
