Some man-made fibres, too, are derived from naturally occurring polymers. For instance, rayon and acetate, two of the first man-made fibres ever to be produced, are made of the same cellulose polymers that make up cotton, hemp, flax, and the structural fibres of wood.
The reason why we were unable to read the lab manual through the tubes containing isotonic and hypertonic solution is because the cells in those solutions remained intact, causing the solutions to be opaque, in the tonicity of red blood cells activity. The reason why we can't read the lab manual is because the cells in the solutions remained intact.
Option <u>(c.) the purity of the protein</u>, will be the right one.
Sodium Dodecyl Sulphate provides a negative charge to each protein as a function of their molecular size. It is an anionic detergent, as well as it is there to determine the relative abundance of major proteins.
After denaturing, proteins get unfolded and gets coated with SDS detergent molecules. The SDS-PAGE technique is used for the separation of protein based on their molecular size/weight/mass.
It is so because as it identifies the proteins by its molecular weight. Therefore, SDS is used in denaturing polyacrylamide gel electrophoresis for the determination of protein molecular weight, the SDS-PAGE is a technique.

If they didn't adapt, they couldn't survive in the changed environment.
Because abiotic factors determine the kind of organisms that are able to live in certain conditions.
Answer:
A.) Pollen are well preserved in the sediment layers because they are highly resistant to decay.
B.) Other indicators that can be used to determine past climates are through the analysis of the width of tree rings and the coral reefs formed underwater.
