Answer:
yes
independent - temperature
dependent - amount of sugar dissolved
Explanation:
When water molecules are heated they move faster and collide more with the sugar molecules. These collisions transfer energy to the sugar molecules. Energy is needed to break bonds. The bonds holding the sugar molecules together or more likely to be broken.
The amount of sugar dissolved is dependent on the temperature of water.
Pure water is very close to a pH of 7. The Great Salt Lake (from what I've read about) can range from 8.2 to 7.7 in different areas. Saliva is between 6.5 and 7.5. And ammonia has a pH of 11.
So the items that have a pH between 5 and 8 are pure water, saliva, and possibly the Great Salt Lake.
Answer:
prevents secretion of upper air passage
Explanation:
to prevent foods and drinks from falling down the airway which is called aspiration and may lead to pneumonia
Why temperature affects heart rate in ectothermic organisms? If the temperature is within the optimal range for enzyme activity more ATP will be produced and the heart will beat faster due to increased metabolic activity and energy availability.
