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.
Answer:
The correct option is A) It is not written by an authority
Explanation:
In the English language, credibility can be described as the quality of an object to be reliable or trusted.
A piece of written work which does not mention the name of the writer may be considered to be not reliable and trustworthy. Hence, the correct option is A.
Other options, like option D, is not correct because a peer- reviewed journal carries authentic information as the work has been rechecked by different people who have expertise on the subject.
The event which takes place during normal fertilization is zygote formation.
<h3>Which event takes place during fertilization?</h3>
The major event which is characteristic of fertilization is zygote, otherwise termed cell formation in which case, the zygote is capable of undergoing cell division to form a new living cell. The fusion of two gametes necessary for fertilization kick-starts several reactions in the egg.

Incomplete question. Here are the missing parts.
What will happen to the substances in this diagram to bring the concentrations closer to equilibrium?
A. The solute will flow into the cell from the surrounding environment.
B. Nothing will change--it is already in equilibrium.
C. Water will flow into the cell from the surrounding environment.
D. Water will flow out of the cell and into the surrounding environment.
My answer:
D. Water will flow out of the cell and into the surrounding environment.
The solute cannot pass through and go inside the cell, water has to flow from the cell to the surrounding environment to bring the concentration closer to equilibrium.
