Answer:
Polar molecules occur when there is an electronegativity (a charge) difference between the bonded atoms. Nonpolar molecules offur when electrons are shapred between atoms of a diatomic molecule or when polar bonds in a larger molecule cancel each other out.
Explanation:
Or basically, polar molecules occur with a charge, as nonpolar molecules do not. And yes, lipids are molecules.
A scientific investigation...
An enzyme is a biological molecule. They are essential to sustain life.
The correct answer as to how heat is involved in photosynthesis and respiration would be that it is not needed. In other words, heat is not involved in photosynthesis and respiration.
- Heat stress actually limits photosynthesis because the functions of relevant enzymes is impacted.
- Heat is not required as input in respiration, but is generated as one of its products. Approximately 60% of the ATP generated during respiration is converted to heat.
Hence, when we are talking about involvement, heat is not involved in both photosynthesis and respiration but only generated as a product in the latter.
