The main component of the cell membrane is a phospholipid bi-layer or sandwich. The heads (the phospho part) are polar while the tails (the lipid part) are non-polar.
Answer:
Gene expression is primarily controlled at the level of transcription, largely as a result of binding of proteins to specific sites on DNA. ... The regulator gene codes for synthesis of a repressor molecule that binds to the operator and blocks RNA polymerase from transcribing the structural genes.

Exergonic is the term in the passage that is most likely be used only in a scientific context.
<u>Explanation:</u>
The term Exergonic is used in a scientific context in the given passage. The chemical reactions takes place either absorbing or releasing energy to its environment in which the reactions takes place. This is due to the breaking or the formation of chemical bonds. It mainly depends on the bond's strength.
When energy is given to the environment in which it takes place then it is called as exoergonic reaction. This occurs due to high strength of the chemical bond that is formed. When energy is absorbed from the environment in which the reaction takes place, it is known as endergonic. The bond that is formed will be weaker and not stronger.
Answer:
. The main structural differences between plant and animal cells are the additional structures found in plant cells. These structures include: chloroplasts, the cell wall, and vacuoles. In animal cells, the mitochondria produces the majority of the cells energy from food.
