The answer is B. A chemical reaction consists of an endothermic stage (energy taken in to break chemical bonds) followed by an exothermic stage (energy released as bonds are formed). The first stage requires this energy input, which is the activation energy. When the activation energy is reached or exceeded, the reaction will occur. Therefore as soon as this threshold is REACHED, it happens
Answer:
The above statement is false.
Explanation:
<em>As we can infer from the question, Thymine is being replaced by Cytosine at position 3 of a genetic sequence. This means that only a single change is being made in the genetic sequence. This change will cause a faulty protein to be formed. The faulty protein will be associated with this genetic sequence. </em>
<em>Hence, not all of the changes existing between the cichlid and coelacanth/frog will be associated with this single base change.</em>
However, instead of replacement of C with T, if an addition or deletion of a base might have occurred, then the entire genetic sequence would have been altered causing many changes.
Brain suffers the least damage during prolonged starvation. Starvation can be termed as a severe deficiency which is in caloric energy intake. It is the most form of extreme way of malnutrition when starvation is prolonged can cause damage to an organ which is permanent or even death.
The one which is termed as the primary cause of starvation is the imbalance between energy expenditure and energy intake.
<span>B. As in most traditional plays, the plot of act 1 of A Doll’s House is designed to provide exposition and build up the tension of the play.

The plot of act 1 of Henrik Ibsen’s A Doll’s House parallel the plots of more traditional plays by designing to provide exposition and build up the tension of the play.
