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: <em>Water potential = pressure potential + solute potential</em>

Since the system is an open one;

<em>Water potential = solute potential = -iCRT</em>

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

b.

<em>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.</em>

The fact that all seven of the pea plant traits studied by Mendel obeyed the principle of independent assortment most probably i
Feliz [49]

Answer:

All of the genes controlling the traits behaved as if they were located on different chromosomes.

Explanation:

Mendel's experiments with pea plants lead to two principles:

  • Law of segregation which states that the pair of alleles (for any trait) of each parent separate, meaning that one allele passes from father and another from mother  to an offspring.
  • Law of independent assortment which states that different pairs of alleles (for different traits) are passed to offspring independently of each other (traits are located on different chromosomes).
