Some chemicals increase the mutation rate, physical agents such as radiation also increase the mutation rate. There are viruses that are mutagens as well. Also, the number of mutations that an organism produce can also be phenotypically plastic.
Hope this helps. (This is the definition my bio teacher gave me.)
Answer:
The cortex is the outermost layer of brain cells.
Explanation:
Your brain contains billions of nerve cells arranged in patterns that coordinate thought, emotion, behavior, movement and sensation.
If you brain is not working you need to destress.
To rearrange it's configuration in order to result in a complete outer energy level
If an exothermic reaction has reached equilibrium, then increasing the temperature will favor the reverse reaction. So, the correct option is B.
<h3>What do you mean by Exothermic reaction?</h3>
Exothermic reactions are those reactions in which the energy or heat is liberated apart from the product.
Increasing the temperature of exothermic reactions causes a decline in the concentration of products while enhancing the concentration of reactants.
Therefore, if an exothermic reaction has reached equilibrium, then increasing the temperature will favor the reverse reaction.
