Answer:
Option (3).
Explanation:
The homeostasis of the body is maintained by the feed back loop system. Two main types of the feedback loop system of the body are positive feedback system and negative feedback system.
Positive feedback system may be defined as the feedback in which the final product increases the output of that product. Pepsinogen is an zymogen that helps in the activation of pepsin enzyme. This enzyme helps in the digestion of protein. The digestion of pepsinogen by pepsin result in the more production of pepsin.
Thus, the correct answer is option (3).
Answer:
The correct option is C, a clam shell have a good possibility of being preserved because it has a hard body.
Explanation:
In evolutionary studies, preservation are made in the form of fossils or remnants.
For an organism to be preserved, it must not decay early and it should be hard enough. When an organism is buried quickly then it will take more time to decay and hence will have more chances to be preserved.
As the clam shells are hard so this quality makes them ideal enough to be preserved.
Answer:
No
Explanation:
Fishes lay eggs and are not warm blooded vertebrates and don't have hair or fur
They say it’s “tree shedding” but each tree changes color by season depending on how much sunlight or darkness they get. Some change when they don’t get enough food.
Because decomposition helps create nitrogen, a lack of decomposition would result in a lack of nitrogen being created.
