Place the following events of a reflex arc in the correct order: 1) motor neuron activation, 2) sensory neuron activation, 3) se
VikaD [51]

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.

During aerobic cellular respiration, what combines with hydrogen ions and the product is released as a by-product of respiration
Rufina [12.5K]
 The correct answer is C, Oxygen.
During aerobic cellular respiration, oxygen combines with hydrogen ions and water is released as a by-product of respiration. 

Explanation; 
Cellular respiration allows organisms to release energy stored in chemical bonds of glucose, and other nutrients. The energy in glucose or other nutrients such as fats is used to produce ATP, which cells use to supply their energy needs. During aerobic respiration (in presence of oxygen), oxygen is reduced and water is produced together with carbon dioxide as by-products.

How does the proofreading mechanisms in viruses affect the frequency of the mutations a virus typically undergoes?
SVEN [57.7K]

Answer:

Explanation:

DNA polymerases are the enzymes that build DNA in cells. DNA polymerase also proofread their work to check for any error the process of which is called proof reading.

If the polymerase detects that an Incorrectly paired nucleotide has been added, it will remove (splicing) and replace the nucleotide with the correct one before it continues with DNA synthesis.

Mismatch repairing also corrects other errors that omit proofreading. They fix mismatched base pairs, replace some insertion and deleted base pair that can result into mutations.

When an error is corrected the rate of mutation is reduced this is because mutation results from error during the DNA formation process either through Insertion of a wrong nitrogenous base, or deletion leading to formation of an entirely new amino acid sequence that result into abnormal phenotype.
