Which of the following is correct observation?

#SCPH28 | Zoology

  1. Niche partitioning allows for selection of differential patterns of resource usage, which can drive speciation

  2. This narrowing of phenotypes causes a reduction in genetic diversity in a population

  3. Extreme phenotype is favored over other phenotypes, causing the allele frequency to shift over time in the direction of that phenotype

  4. The phenotypes grade become wide and caused increases the genetic diversity in a population

C. roseus cells immobilized in Ca-alginate beads of diameter 0.5 mm are used for production of indole alkaloids (IA) in a fluidized-bed bioreactor. The rate limiting nutrient is glucose and no intraparticle diffusion limitations exist. Use the following data: Flow rate of the feed: Q = 1 l/h, Glucose in the feed: So = 30 g/l, Plant Cell Concentration: X = 6 g/l reac. The rate constant for IA formation: k = 5 d-1 (g/l)^-1 Ks = 0.4 g/l, Column diameter: Do = 0.15 m. Growth is negligible and Monod kinetics is valid. For 95% glucose conversion determine height of the column

We need to minimum buffering capacity is required so that the pH value of the samples analyzed does not have any influence on the system, 
What would happen if we used the higher buffering concentration
a) more electric power is applied, resulting in higher heat development. 
b) less electric power for less time  is applied, resulting in very high  heat development
c) higher buffering concentration need more electric power resulting increases in the temperature will increase the mobility and rate of migration of ions.
d) using the higher buffering concentration shows no affect at all
