Transmembrane proteins are found in the plasma membrane. Hydrophilic regions are embedded
<span>
within the membrane, and Hydrophobic regions project from both surfaces of the bilayer.

Approximately 20-80% of the cell membrane is composed of lipids, the rest, is made up of protein. The lipid layer of the membrane gives it flexible and permeable characteristic. While the protein part assists in transport of molecules it needs to survive.<span>

Answer:
Extra carbon dioxide in the atmosphere increases the greenhouse effect. More thermal energy is trapped by the atmosphere, causing the planet to become warmer than it would be naturally Explanation: yeah
Fire is not a living thing, and abiotic factors are the factors in an ecosystem that are non-living. So, fire is an abiotic factor in an ecosystem, though its not mentioned alot.
Answer: ingestion, propulsion, mechanical or physical digestion, chemical digestion, absorption, and defecation.
Explanation:
Both nuclear and chemical equations are balanced according to the total mass before and after the change.
In every equation or reaction, the total mass of the reactants must be equal to the total mass of the products. In other words, all reactions - be they chemical or nuclear - must obey the law of conservation of mass.
The law of conservation of mass states that mass can neither be created nor destroyed, but can be converted from one form to another during a reaction.
Thus, in order to balance reactions involving chemical or nuclear reactants, the total mass before the reaction must be equal to the total mass after the reaction.
