Gametes are an organism's reproductive cells. They are also referred to as sex cells. Female gametes are called ova or egg cells, and male gametes are called sperm. Gametes are haploid cells, and each cell carries only one copy of each
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.
2. The stepper the gradient the more energy the stream has as it flows down.
3.. the higher the gradient, the higher the velocity and the ability to erode and carry sediment . As the gradient decreases toward the coast,stream velocity slows and the ability to transport sediment decreases.
