Answer:
When hydrogen peroxide is added to a chicken liver sample exposed to lemon juice the chemical reaction will be slower and appear some bubbles within the first minute (option B).
Explanation:
The liver contains an enzyme called catalase, whose function is the degradation of hydrogen peroxide (H₂O₂), an intense reaction that produces gas and heat. <u>The activity of this enzyme must occur at an appropriate pH, so changes in pH can affect the activity of catalase</u>.
- Under normal conditions, when a liver sample is exposed to H₂O₂, bubbles and foam appear in the sample as a result of the catalase reaction.
- When the chicken liver sample is subjected to the acidic lemon juice, the reaction will occur, but more slowly.
This is because the activity of the catalase enzyme, present in the liver, continues to occur —although it decreases— and will form few bubbles over a longer period of time.
The other options are not correct because:
<em> A. At a lower pH, the reaction will not form many bubbles.
</em>
<em> C. Even if the reaction is minor, and produces very few enzymes, it will always occur.
</em>
<em> D. Although the catalase/H2O2 reaction produces heat, it is impossible for the liver to catch fire and cause evacuation from the school, even less so with a reaction whose speed has been slowed down.</em>
If the warm air rises high enough, the air will eventually cool to its dew point. When it cools to its dew point, it begins the process of condensation. Starting from here, as air rises, the heat of condensation stored in water vapor will gradually release.
Answer:
the reaction was exothermic because the heat dissipated quickly after a mere few minutes.

Answer:
If the calcium levels in blood increases, then there is increase in blood glucose level.
Explanation:
Calcium in blood plays a vital role of homeostasis in regards to level of secretion of insulin. If the calcium level is altered, the homeostasis mechanism is hampered. Several researches have shown that alteration of serum calcium level affects the metabolism process of carbohydrate and makes the person vulnerable to risks of diabetes mellitus and associated complications. Hence during calcium supplementation, the person's blood glucose level must be considered.
