Answer: This is a positive feedback loop.
Explanation:
The protein digestion in the body is an example of the positive feedback. The gastric secretions is stimulated chiefly by the action of three chemicals.
These chemicals are acetylcholine, histamin and gastrin. These chemicals stimulate the parietal cells to secrete HCL and intrinsic factors.
The chief cells secrete pepsinogen in response to the gastrin and ACh. As the dietary proteins are digested, it breaks down the amino acids and peptides.
This stimulates the G cells of the stomach to secrete more gastrin. This is how the positive feedback loop for the protein digestion works.
Answer:
A blizzard can form when warm air combines with a high pressure system.
Explanation:
A high pressure zone is defined by cold air mass that has higher density than surrounding air mass. Therefore when a warm air current blows towards the high pressure system, the warm air mass rises over the cold air mass of the high pressure system.
The warm air begins to cool at the front between the cold air mass and warm air mass. Usually for a blizzard to occur the cold air mass is usually below freezing point temperatures. Therefore the moisture in the warm air cools and freezes into snowflakes. This is why the winds of a blizzard are accompanied by snowflakes akin to a winter storm.

Answer:
Explanation:
A community structure is define by the diverse organism present and the various number of species.
A community requires both biotic and abiotic factor to form a good structure.
Base population is needed - this are the primary producer, that transfer energy to other organism in the environment. The produce their food themselves.
Consumers - consumers feeds on producers, herbivores animals feeds on producer/plant while carnivores feeds on herbivores. Energy is then transfer when they chemical reaction takes place via the food comes
Decomposer - They act on the dead and remains of plant and animal. They help release nutrient back into the soil. Example of decomposer is earth worm.
