Water is a polar molecule because its opposite ends have opposite electric charges.
I believe that hair and limbs are homology because all mammals have hair and similar limb structure. Hair loss and social behavior on the other hand are homolasy because not all mammals have them. Homology is the similar traits due to common ancestry while homoplasy is similar traits for other reasons other than common ancestry.
Answer:
As pressure increases, volume of an object tends to decrease.
Explanation:
The answer is respiration.
The burning of fossil fuels is known as combustion. It is often compared with cellular respiration.
The general equation of cellular respiration is:
glucose + oxygen → <span>water + carbon dioxide
</span>
The general equation of combustion is:
fuel + oxygen → <span>water + carbon dioxide
Both reactions involve breaking down of large molecules (glucose and fuel) using oxygen into water and carbon dioxide. In both reactions, chemical energy is transformed into more useful form.</span>
