Answer:
The reflex arc follows this sequence of events
1. sensory receptor activation
2. sensory neuron activation
3.information processing
4. motor neuron activation
5. effector response
Explanation:
Reflex arc is the pathway of nerves during a reflex action. An example of a reflex arc is when we accidentally touch a hot object. First, the receptor in the skin detects a stimulus in this case the change in temperature. Second, the sensory neuron transmit the electrical impulses to the Central Nervous System for information processing. Then relay neurons connect sensory neurons to motor neurons. Third, motor neurons sends electrical impulses to an effector wherein the effector produces a response ( muscle contracts to move the hand away from the hot object. This happens in a split of seconds.
The structure is a phospholipid bilayer. There are many phospholipids which contain a water loving phosphate end and a water hating lipid (fatty) end. The phosphate ends all point out words while the fatty ends are inside.

The answer to this question with the options presented in the problem would be A. 50.
It is said by experts that in the energy pyramid, 90% of energy is lost for life processes such as photosynthesis, respiration, and the like. So this means that only 10% will remain for the consumer to have. That would be saying that if suppose there are 500 units of energy available at the producer level of the energy pyramid, to get the units of energy available to the first-level consumer is to have the 10% of 500 which is 50.
