Answer:
It consists of the mouth, or oral cavity, with its teeth, for grinding the food, and its tongue, which serves to knead food and mix it with saliva; the throat, or pharynx; the esophagus; the stomach; the small intestine, consisting of the duodenum, the jejunum, and the ileum; and the large intestine, consisting of the cecum, a closed-end sac connecting with the ileum, the ascending colon, the transverse colon, the descending colon, and the sigmoid colon, which terminates in the rectum. Glands contributing digestive juices include the salivary glands, the gastric glands in the stomach lining, the pancreas, and the liver and its adjuncts—the gallbladder and bile ducts. All of these organs and glands contribute to the physical and chemical breaking down of ingested food and to the eventual elimination of nondigestible wastes.
Answer:
The correct answer will be options-
1. they share genetic similarities
2. they can interbreed
3. they fall under the same genus
Explanation:
The taxonomic studies help the organism to identify, nomenclature and classification of the organism.
The classification system helps organize the organisms into several groups based on the similarity of the morphological characters. The species is the lowest group of the system which contains the organism which is reproductively isolated from the other group of organism.
If two organism is found to be of the same species shows that they share the same gene pool, belongs to the same genus and they can interbreed.
Thus, the selected options are the correct answer.
Because the soil didn't have the same nutrients it has now due to lack of decomposition of other plants and animals.
