Answer: The additional protection in the body of aerobic organisms are that they can fight with the ROS radicle formed in the body.
Explanation:
The aerobic organism use oxygen as a final electron acceptor. The aerobic organisms have enzymes in the body which helps in getting from the reactive oxygen species. These enzymes are superoxide dismutase, peroxidase and catalase.
Anaerobes are vulnerable to these ROS which is produced by their own metabolism. They do not contain the enzymes such as superoxide dismutase and catalase that can help them to survive in these conditions.
Hence, because of antioxidants the aerobic organism can survive in oxygen and anaerobes cannot.
The correct answer is option B. The scientists were studying if the mud snails can reproduce both sexually and asexually. The characteristics in the study included parameters such as the mating season, number of offspring, effect of environmental stress conditions and lack of mates. Out of all the parameters being studied can affect asexual reproduction in the mud snail but lack or presence of mates is a parameter required to be studied to determine the mode of reproduction i.e. sexual or asexual because need for mates or mate dependent reproduction occurs in case of sexual reproduction.
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.
