Cone cells in the retina of the eye detect color.
There are three types of cone cells.
Two of them detect light of different wave lengths, one medium and the other long.
And the third detects the overall intensity of the light source.
Your brain uses this information to interpret the combination of those three receptors to give you the sensation that you perceive different colors.

Feliz [49]

Answer:

The right solution according to the question is provided below.

Explanation:

According to the question,

(a)

The initial conditions will be:

DO = $\frac{(40\times 1.8)+(260\times 7.6)}{40+260}$

= $\frac{2048}{300}$

= $6.826 \ mg/L$

The initial oxygen defict will be:

Do = $8.5-6.826$

= $1.674 \ mg/L$

The initial BOD will be:

Lo = $\frac{(40\times 25)+(260\times 3.6)}{40+260}$

= $\frac{1936}{300}$

= $6.453 \ mg/L$

(b)

The time reach minimum DO:

tc = $\frac{1}{(kr-kd)} ln{(\frac{0.76}{0.61} )[1-\frac{1.674(0.76-0.61)}{0.61\times 6.453} ]}$

= $\frac{1}{0.15}\times ln \ 1.158$

By putting the values of log, we get

= $0.973 \ days$

The distance to reach minimum DO will be:

Xc = $\frac{1.1\times 3600\times 24}{5280}\times 0.973 \ days$

= $18\times 0.973$

= $17.5 \ miles$
