Answer:
<h2>TRUE </h2>
Explanation:
Normally , substrates bind to the active site of the enzyme and catalyzes the reaction.
If there is sufficient amount of enzyme present, the reaction rate increases, because additional active sites could speed up the reaction. As the amount of enzyme is increased , the rate of reaction increases.
If there is insufficient amount of enzyme present , The reaction rate increases , but not so fast as it otherwise would.
Hence the statement an increase in the concentration of enzyme will increase the reaction rate is true.
The process responsible for the movement of substance A into the cell will be active transport.
<h3>What is active transport?</h3>
It is a kind of cellular transportation of molecules against their concentration gradients through the use of energy.
Active transports are different from passive transports. The latter has to do with the cellular transportation of molecules in and out of the cell without involving the use of energy.
In the diagram, there is more concentration of substance A inside the cell than the outside. Thus, moving substance A into the cell will be a movement against its concentration gradient.
The movement of substances against concentration gradients always requires energy, usually in the form of ATP - active transport.

Answer:
Transient ischemic attack (TIA) may be defined as a medical condition in which individual suffers from numbness, difficulty in speaking and dizziness. The body loss is completely lost for few minutes.
In the given question, Robert might suffers from TIA. In TIA the brain cells of the body feels the anoxia or the cells are completely deprived of the oxygen. This TIA remain last only for few seconds to minutes and might cause the other serious problem.
