Low infiltration capacity means that the soil cannot absorb much water per volume. The first step in erosion in a landscape dominated by low-infiltration capacity is the raindrop splash. This is where raindrops displace the soil from their original place because the soil cannot absorb adequate amounts of water.

Recombinant DNA technology has produced medically useful products. Most of these products are _______ that are normally present

scZoUnD [109]

Answer:

proteins; purify; expression

Explanation:

One of the products of recombinant DNA technology is antibiotics. To have penicillin, we used to have to breed fungus that produces the drugs. With recombinant DNA technology, you can extract the DNA that needed to produce penicillin, then put it into a bacteria using an expression vector. This technology will allow us to produce a specific protein (whether its enzyme, hormone, or anything) easier.

The solutions in the two arms of a U-tube are separated by a membrane that is

IgorC [24]

Answer:

See the answer below

Explanation:

Recall that: Water potential = pressure potential + solute potential

Since the system is an open one;

Water potential = solute potential = -iCRT

i = number of particles the molecle will make in water (1)

C = molar concentration

R = Pressure constant = 0.0831 liter bar/mole K

T = temperature in kelvin = 22 + 273 = 295 K

To calculate water potential on side A:

C = 1 M

Water potential = - (1 x 1 x 0.0831 x 295) = -24.51 bars

For side B:

C = 2 M

Water potential = - (1 x 2 x 0.0831 x 295) = -49.03 bars

Since side A has higher water potential than side B, water will flow from side A to side B until equilibrium is established between the two sides. Water always flows from the region of higher water potential to the region of lower water potential.
