What would happen if a researcher failed to realize a thermometer he or she was using has a Celsius and Fahrenheit scale?

Chemistry

sveticcg [70]3 years ago
3 0

Answer:

To obtain a more accurate read on temperature, the researcher should make sure to measure temperature by Celsius degrees rather than Fahrenheit.

Explanation:

Temperature is a measure of heat intensity. In food science experiments, you should always require an exact description of heat intensity. The most commonly used unit of temperature in the laboratory is the Celsius degree because the Celsius temperature scale is based on the boiling and freezing points of pure water. The difference between the points of boiling and freezing temperatures (at 1 atmosphere of air pressure) is divided into 100 equal units, making a Celsius degree 0.01 of the difference between the boiling and freezing points of water, making it the most accurate method of exact temperature reading. It is important to use the Celsius scale if you have a thermometer that reads Celsius and Fahrenheit.

When a plant is entering the Calvin cycle of photosynthesis_____.
Andrei [34K]

B). light energy is not required to proceed

Explanation:

In the Calvin cycle of photosynthesis, light energy is not required. The Calvin cycle is light independent and it is made up of a series of redox reactions.

  • During photosynthesis reactions, green plants manufacture their food using carbon dioxide, sunlight and water.
  • During the Calvin cycle aspect, light energy is not required for chemical reactions to take place. The light energy helps to move electrons.
  • The cycle is also known as dark reactions.
  • It is at this stage that carbon dioxide combines with water to form glucose.
  • The reaction is initiated with light energy which produces NADPH and ATP.
  • The Calvin cycle follows by using the NADPH and ATP to produce glucose in the dark phase.
