Ainat [17]

The correct answer is: Both experienced the most rapid uptake of glucose at the beginning of the experiment.

The difference between pigs would be in their uptake of glucose during the whole experiment, where the younger guinea pig's cells took up more glucose than the older guinea pig's. This is because older guinea pigs have fewer glucose transporter proteins.

Expiratory reserve volume (ERV) You ask your lab partner to inspire a normal tidal inspiration, and breathe out a normal tidal e
Bumek [7]

The average expiratory reserve volume or ERV is 810.

<h3>What is expiratory reserve volume?</h3>
  • Expiratory reserve volume or ERV is the amount of air that is exhaled forcibly.
  • This can be measured using a spirometer and is used to detect restrictive lung diseases.
  • It is the maximum amount of air that can be exhaled after normal tidal volume is exhaled.
  • Respiratory volume is the volume of air which is either inhaled, exhaled or stored in your lungs.
  • The doctors estimate the reserve volume with the help of spirometer to determine some lung diseases.
  • Once diagnosed with a lung disease, spirometry is used to monitor it.
  • Here, 3 readings of ERV are taken, calculate the sum of the these and divide by 3 to calculate the average ERV.
  • ERV= (800+ 850+ 780)/ 3= 810

Diego is conducting an experiment to investigate how temperature affects chemical change. He has three pieces of cheese that he
valkas [14]

The piece of cheese in the refrigerator had the least amount of chemical change.

  • Moulding occurs on substances which are warm and moist
  • Mold thrives in warm and humid places
  • In refrigerators, the environment is cool and dry
  • This environment hinders the growth of mold
  • The bacteria and fungi require optimum temperatures to flourish, which is not present in a refrigerator
  • The cheese placed outside and on the counter will grow mold as those environments do not arrest the growth of mold
  • Refrigeration ensures that food is not spoilt

Therefore, the least amount of chemical change takes place on the cheese placed in the refrigerator.
