What are two techniques used to restore biodiversity
Zarrin [17]

Two techniques that are used in order to restore the biodiversity are the sawing of native seeds or planting individual plants, and the reintroduction of animal species native to the ecosystem.

The restoration of the biodiversity is practically trying to get an ecosystem in its initial, pre-destruction condition, and help it function without any human assistance after certain amount of time.

All restorations of the biodiversity are hard and take time, and there's no guarantee that the outcome will be as planned and wanted. Initially, there the sawing of native seeds and planting individual plants, which is crucial as the plants are the basis of the ecosystems. After that animal species are introduced, small and large, herbivores, omnivores, and carnivores. The people initially have to assist the functioning of the ecosystem, but the idea is to make it function properly over time on its own.

What would be a different way by which you could determine the retention volume for the proteins and molecules analyzed in today
Lunna [17]
An alternative approach to this experiment would be the use of  Spectroscopy. Instead of trying to visualize and guess the fraction with the most intense color, the exact fraction could be found with Spectroscopy. A range of fractions that are the most intense are measured with the absorbance value for each one. The fraction with the highest absorbance value will be the most intense fraction.This method guarantees that the <span>correct retention volume is recorded.</span>
