Satiation is the feeling of fullness and satisfaction that typically comes after eating because of signals from the pancreas, liver, gastrointestinal tract, and brain.
<h3>What is
gastrointestinal tract?</h3>
The digestive system's path from the mouth to the anus is known as the gastrointestinal tract (GI tract, digestive tract, alimentary canal). All of the major digestive system organs, such as the esophagus, stomach, and intestines, are located within the GI tract in both humans and other animals. Food that is consumed by mouth is broken down into nutrients and energy, and the leftover waste is ejected as feces at the anus. An adjective describing the stomach and intestines is "gastrointestinal."

Biodiversity is essential to an ecosystem's resistance against viruses and famine. In history, there has been many cases in which a lack of biodiversity has allowed a virus or disease to endemically wipe out an entire species of plant. This will subsequently affect all consumers of each trophic level. Ex: A disease that attacks the DNA of only one certain species of plant would cause decreases in the population of the organisms that rely on eating that plant, the organisms that rely on eating those organisms, and so on. This is caused by a decrease in food source, thus not being able to sustain the ecosystem's demand, thus naturally killing off any organisms that would not be able to find a sufficient food source.
<span>They are misleading, because dominant alleles do not dominate or prevent recessive alleles from doing a job. Also, one allele can be considered dominant in one regard and recessive in another. It just depends on what you are trying to do with it.</span>
<h3><u>Answer</u>;</h3>
Key
A sorting device that is useful in classifying by observation is a <u>key</u>.
<h3><u>Explanation</u>;</h3>
- <em><u>Classification key or taxonomic key is a device that is used by scientists to identify unknown organisms. </u></em>
- They are constructed so that the user gets a series of choices about the characteristics of the unknown organisms.Thus, by making the correct choice at each step, one is led to the identity of the specimen.
- Therefore<u><em>, keys can be used to identify a living organism or determine which group it belongs to</em></u> by answering questions on the key about characteristics of living things.
