Answer:

2. 2H2O2 -> 2H2O+ O2

Explanation:

This equation is balanced because there are equal amounts of each element on each side. 4 Hydrogen on the left, 4 On the Right. 4 Oxygen on the Left, 4 on the right.

Although 1 is balanced it is not the Chemical equation for hydrogen peroxide (H2O2)

2. is not the equation for Hydrogen Peroxide

4. Balanced although this one does not show oxygen as a gas ( when oxygen is a gas it is O2)

From an evolutionary perspective, what adaptive value do mirror neurons have?
Akimi4 [234]

Mirror neurons are said to be the factors behind social imitation. Neurons are the main cell of the nervous system which is responsible for communication of organs and control of many bodily functions. In an evolutionary standpoint, mirror neurons are an advantage because humans are able to replicate and imitate skills, behaviors and practices which they find beneficial and advantageous in the wild. Among their social peers, mirror neurons help these individuals practice social inclusion through culture, values and practices for increased group cohesion and cooperation.

In light of the all or none law of muscle contraction, how can you explain the graded response?
Andrews [41]
<span>In the "all or none" law of muscle contraction, it states that when the stimulus applied exceeds threshold then the the nerve sending signals to a few muscle fibers will give a complete response; contraction. Graded response is dependent on how many motor units have been recruited. The more motor units, the greater the force in the contraction.</span>
