C Oxygen.
Mammals breath in oxygen and releases it as CO2 gas.
Solar energy, which is an abiotic factor, by the way, enters the ecosystem through the process of photosynthesis. ... The organisms in an ecosystem that capture the sun's electromagnetic energy and convert it into chemical energy are called producers. Btw I’m in middle school lol
Answer:
<u>Double bonds in the fatty acid tail</u> is the characteristic of a phospholipid contributes to the fluidity of the membrane .
Explanation:
Phospholipid -
The phospholipid has a hydrophobic region or the water hating , and is a non - polar region , hence , it can interact with the non - polar molecules in a chemical reaction .
And phospholipid has a hydrophilic region or the water loving , and is a polar region , hence , this region can form hydrogen bond with water .
Hence ,
When , a phospholipid is placed in water , it forms a ball or a cluster .
The two hydrophobic tails and the hydrophilic head together forms a phospholipid molecule .
The hydrophilic region have a phosphate-containing group which is attached to the glycerol molecule and the hydrophobic tails have unsaturated fatty acid and are the long chain hydrocarbon .
Answer:
Proteins are polymers; the monomers which make them up are amino acids.
