Answer:c. duodenum of the small intestine
Explanation:
The digestive system is a series of hollow organs joined in a long, twisting tube from the mouth to the anus Inside this tube is a lining called the mucosa. In the mouth, stomach, and small intestine, the mucosa contains tiny glands that produce juices to help digest food.
Two solid organs, the liver and the pancreas, produce digestive juices that reach the intestine through small tubes. In addition, parts of other organ systems (for instance, nerves and blood) play a major role in the digestive system.
The statement 'artificial selection decreases the rate of natural selection and change within a population' describes how artificial selection can decrease a population's biodiversity. It is a human-driven process.
<h3>Artificial selection</h3>
Artificial selection refers to the human-driven process by which different organisms (either plants or animals) are selected in order to combine desired features in offspring.
In artificial selection, organisms are mated (crossed) in order to select the progeny having desired phenotypic traits.
This process (artificial selection) leads to a decrease in natural genetic variation (biodiversity), which may have negative consequences in the successive rounds of selection.
