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.
So basically water is a polar molicule. So when it comes to the structure, water is able to form many hydrogen bonds and the way the atoms are able to bond together adds to the water's special properties.
The earth is surrounded by <em>a layer of</em> gases called the <em>atmosphere</em>. The atmosphere is very <em>important </em>to life on <em>Earth</em> and does many <em>things</em> to help protect life and help<em> life </em>to survive.
The atmosphere absorbs the <em>heat</em> from the <em>Sun </em>and keeps the heat <em>inside</em> the atmosphere helping the <em>Earth </em>to stay warm, called the <em>Greenhouse </em>Effect.
The macromolecule shown here is an amino acid because of the carbon that bears the amine group and the acid group.
<h3>What is a macromolecule?</h3>
The term macromolecules refers to those molecules that have a large molecular weight. They can mostly be found in biological systems and play various roles in the body
The macromolecule shown here is an amino acid because of the carbon that bears the amine group and the acid group. There are four elements present as follows;
- Carbon - 6
- Hydrogen - 14
- Nitrogen - 2
- Oxygen - 2

Answer: Exergonic reaction; Endergonic reaction
In coupled reactions, the energy released by an exergonic reaction is used to drive an endergonic reaction. ATP breakdown is often coupled to cellular reactions that require an input of energy.
Explanation:
Cellular reactions include Exergonic and endergonic reactions. An exergonic reaction is one that occurs spontaneously and brings about the release of energy (in form of ATP). On the other hand, an endergonic reaction proceeds only with the input of energy.
Thus, exergonic reactions are usually coupled to endergonic reactions
