Explanation:

Reconstruction was the period in the united states during which the Civil war took place and the laws were made to provide equity to the slaves ending slavery.

The problem arises due to the reunion of the 11 states of the South to the Union which seceded earlier. Slavery was more practised in the Southern states compared to Northern states.

The Republican party did corruption from 1869 to 1877 which allowed due to which they lost their election of 1877.

In 1877, a special electoral commission was established in favour of Hayes and Democrats took benefits of this condition.

When Hayes was selected, he withdrew the federal troops from the South which allowed the Democrats to gain their seats in South and ended Reconstruction.

Example 1: Two different enzymes are able to catalyze the same reaction, A → B. They both have the same Vmax, but differ their K

luda_lava [24]

Answer: (a) = 0.022mmoles/minute; (b) = 0.00022mmoles/minute; (c) = 0.022mmoles/minute

Explanation:

The Michaelis- Menten equation is used to show the relationship between substrate concentration and reaction rate.

The equation is Vo = Vmax[S]/(Km + [S]

where Vo is the initial velocity, Vmax is the maximum velocity, [S] is the substrate concentration, Km is the Michaelis constant.

(a) For enzyme 1; Vo = 0.002mmoles/minute, Vmax = ?, [S] = 0.1mM, Km =1.0mM; making Vmax subject of the formula;

Vmax = Vo * (Km + [S])/ [S]

Vmax = 0.002*(1.0 + 0.1)/ 0.1

Vmax = 0.022mmoles/minute (Vmax for Enzyme 1&2)

(b) Vo = Vmax[S]/(Km + [S]

Vo = 0.022 * 0.1/(10+0.1) = 0.00022mmoles/minute

Vo = 0.022*1000/(1.0+1000) = 0.022mmoles/minute

What is the likeliest limiting factor restricting phytoplankton to approximately the top ten feet of the ocean, rather than deep

serg [7]

Quality of light is the limiting factor restricting phytoplankton to approximately the top ten feet of the ocean, rather than deeper

Explanation:

When sun rays pass through the water in the oceans, they are quickly diffused and cannot penetrate very deep into the deep water layers. Remember that phytoplanktons are photosynthetic organisms and hence require sunlight to manufacture their own food. They, therefore, cannot grwo in deeper layers of the oceans. They are only found in the photic zone.

The quality of light is especially of most importance and hence the major limiting factor. Red light, of longer wavelength, and which is the major wavelength of light that is used the most by photosynthetic organisms, diffuses very fast than blue light when it passes through water. Therefore the more reason phytoplankton is found in the top ten feet of the ocean, rather than deeper.
