Answer:
D) Water dissolves some molecules while causing the aggregation of others because of hydrophobic and hydrophilic interactions.
Explanation:
Sugars tend to dissolve, while lipids aggregate out because sugar has hydrophilic (water loving) interaction with water and on the other hand lipids have hydrophobic (fear of water) interaction with water. Water is a polar solvent and only polar solute dissolve in it due to phenomenon of like dissolve like, while lipids does not dissolve in it because lipid is non-polar in nature. In this case, sugar is hydrophilic while lipids is hydrophobic.
Answer:
In the 1960s, Lynn Magulis came up with the theory of endosymbiosis. Different evidence supports this theory that the cell organelles like chloroplasts and mitochondria were once utilized by the independent living species. Both of these organelles exhibit their own genetic material. The mitochondria cannot differentiate to produce chloroplasts and vice versa.
However, the fact that the mitochondria are found in all the cells of eukaryotes, while the chloroplast is witnessed only in certain specific cells, shows that the evolution of mitochondria took place much earlier than the chloroplasts.
The R group is what allows amino acids to form macromolecules with different properties. every amino acid has the same basic structure, the only difference is what the R group is made up of. The similarities allow the amino acids to form a chain while the differences allows them to have different functions. Hope this helped!
