Answer:
Option B, weight greater than your true weight
Explanation:
When a person stand on a scale in an elevator, his inertia tries to remain constant and stable. Thus when a lift starts moving upward it presses against the feet of that person in order to lift him/her up. In doing so an apparent weight is applied on the person which do not change with speed and it is due to this weight that scale shows a higher reading when elevator moves up.
Hence, option B is correct.
As a result of its involvement in a reaction, an enzyme is unchanged.
Enzymes are catalysts that speed up chemical reactions that occur within the biological systems (they increase the reaction rate by lowering its activation energy). Enzymes react with substrate that binds to them (key-lock mechanism) and convert the substrate into the product. Most of enzymes are proteins by their structure but a few are catalytic RNA molecules-ribosymes.
Enzyme activity can be affected by other molecules (activators and repressors), pH, temperature etc.
The most important reason for food handlers to understand and apply food safety knowledge is to prevent the spread of illnesses through food.
Food workers play a critical role in ensuring food safety, those who do not practice proper personal hygiene, including hand washing at appropriate times and using appropriate methods can contaminate food. It is therefore; very important for food workers to understand and apply food safety measures so as to prevent spread of diseases through food.
