2 would be A because fertilization is where the sperm cell and egg unite. 3 would be C because in the picture you can see how the division is occuring.
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.
Answer:
Both store materials needed by the organism.
Explanation:
Proteins and carbohydrates are two biomolecules present in living organisms. They perform varying functions in the body of an organism. According to this question, a specific protein (ferritin) and carbohydrate (glycogen) is described.
Ferritin is a protein molecule containing Iron (Fe). Iron is needed by living organisms as it plays a vital role in organism's metabolism. On the other hand, glycogen is a carbohydrate molecule that is made up of glucose molecules, needed by living organisms.
Based on the description of the two biomolecules provided, they are similar in their primary functions for an organism in the sense that THEY BOTH STORE MATERIALS (glucose and iron) NEEDED BY AN ORGANISM.
The answer I believe is number 1
