By having a unicellular form, a protist will gain two major advantage:
1. It would be able to reproduce on its own, asexually without having to look for sexual partners. It will be able to reproduce by binary fission, multiple fission or budding.
2. It will benefit from a simple body system that does not need system specialization. Having specialized systems with many parts can results in some of the system having problems at times.
Water!!! It’s is water.....
Explanation:
Percentage w/v means that weight of solute present in 100 ml of a solution. Hence, 15% w/v means that 15 gram of solute per 100 ml of solution.
Hence, for 2 L (or 2000 mL) preparation the amount of mass will be calculated as follows.
= 300 g
Thus, we can conclude that weight of Tris-HCL required is 300 g.
