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.
When a scientist finds in the field, the scientist first compare to other known organisms to organisms that are physically similar to the organism. This is verified through encyclopedia and database of organisms. Then the scientist then compares genetically one organism to another organism.
One reason is that they can use the computer for modeling for what they’re studying (ex: bacterial division)
Incomplete dominance is when both of the the alleles represented are heterozygous thus creating a third phenotype known as a blend e.g white and red flowers gives a pink one. Whereas dominant recessive both alleles are homozygous and thus the phenotype depicts that gene.
