Answer:

Reinforcement

Explanation:

Reinforcement can be referred to as anything that can be used to increase, enhance or strengthen a desirable behavior in a person or an organism. Reinforcement is of two types, they include positive reinforcement and negative reinforcement. Positive reinforcement has to do with adding a reward in order to enhance a desirable behavior, while negative reinforcement has to do with removing an undesirable thing in order to strengthen a desirable behavior.

From the question asked,  because the presence of insects after moving the decaying logs increased the frequency at which the bears moved the decaying logs, the finding of the insects is, therefore, a reinforcement. The finding of the enhanced or strengthened the desirable behavior.

Enolase is an enzyme that catalyzes one reaction in glycolysis in all organisms that carry out this process. The amino acid sequ
Tom [10]

Answer:

Enzymes are influenced by changes in pH. Enzymes are best dynamic at ideal pH. It is the most favorable pH value - where the compound is most dynamic. Above and beneath to this ideal pH influence enzyme action. Accordingly enzyme show catalytic action at ideal pH.  

At the point when enzymes are st low or high pH. Hydrogen particles interface with amino corrosive present at dynamic site. In this way changes their state of amino acids, their legitimate direction and influence enzyme movement.  

While estimating action of enolase . 2 phospho glyceraldehyde is a substrate for enolase included a response tube. After appropriate in hatching measure of item is estimated (PEP). Proportion of PEP to 2 phospho glyceraldehyde gives thought regarding enzyme action.  

For negative control, we will take a response tube, without having any enzyme enolase in it. Along these lines we will ready to preclude any change of 2 phospho glyceraldehyde to PEP without enzyme.  

All compound present in our body are adjusted to as per the earth where we are living. In this manner makes us effective in C. aurantiacus ideal temperature for enolase is 55 degrees. So this catalyst will consistently work best at 55 degrees than at 37 degree .
