The three examples of stimulus include;
1. Hit the skin with a needle or pin is a good example of stimulus. The sudden removing of the hand is the response.
2. When somebody bangs a door you jump if you were unaware because of the sound. The jumping is the response to a stimulus.
3. Holding a hot plate we fling hand away from it. The stimulus here is holding the plate while removal of the hand is the response.
Stimulus is the change or cause in an organism's surrounding which causes the organisms to react.
False, then the second one the answer is sweat glands
Answer:
b. Yes, the average efficiency is 10%
Explanation:
The average efficiency at each trophic level is 10% because there is about 10% of energy is transferred from one trophic level to another. In some trophic levels the efficiency of organisms is 20% but in most of the trophic level has 10% efficiency so that's why the average efficiency is 10%. Yes, this ecosystem obeys the Lindeman's Law for ecological efficiency due to its 10% of ecological efficiency.
Density-dependent regulation can be affected by factors that affect birth and death rates such as competition and predation.
The correct answer is A. Between the visceral and parietal layers of serous membranes
Explanation:
Serous fluid is a type of pale yellow fluid similar to mucus that is secreted by certain membranes to reduce friction in body cavities. This can be found on different organs in the body including the digestive system, for example in the peritoneum that encloses multiple organs in the abdomen. Additionally, serious fluid develops between two main layers: the visceral layer that covers the organs and the parietal layer that follows the visceral layer. According to this, serous fluid reduces friction "between the visceral and parietal layers of serous membranes".
