Adenine and guanine have a fused-ring skeletal structure derived of purine, hence they are called purine bases. ... Similarly, the simple-ring structure of cytosine, uracil, and thymine is derived of pyrimidine, so those three bases are called the pyrimidine bases.
Foods that contain more than one type of molecule help us meet our daily requirement of nutrients. There is a limit to how much we can eat in a day, so if nutrient rich foods are consumed, we can easily provide the necessary building blocks for our bodies to maintain healthy function. This is not possible with foods that contain only one type of molecule.
The obvious answer is a bc it does not use and toxic fuels
Answer:
1.) The solute molecules will not move between the two sides because the membrane does not have large enough spaces for the molecules to move through. The water molecules will move to the right side because water moves to places of a higher solute concentration.
2.) The right side represents high concentration because it contains the majority of the solute molecules.
3.) The left side represents low concentration because it contains a small amount of solute molecules compared to the right side.
