As part of a science experiment, Jose did a test for starch on a slice of apple and a slice of potato. The yellow-orange iodine
Sever21 [200]
If iodine solution reacts with starch, it will change color into black.
Since the yellow-orange iodine solution stayed the same <span>color when it was put on the apple, it can be concluded that there is no starch in the apple. On the other case, the black color of the potato suggests that there is a great amount of starch in the potato. Anyway, this does not mean that there is no starch in the apple at all. As fruits ripen, starch slowly changes to sugar. Iodine cannot react with sugar, so the black color in the apple is missing.</span>

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>

1c) If the amino acid sequences in the proteins of 2 organisms are similar, why will their DNA also be similar?
Trava [24]

Answer and Explanation:

Because the DNA sequence determines a protein's amino acid sequence, a gene shared by two closely related organisms should have similar, or even identical, amino acid sequences. That's because closely related species most likely diverged from one another fairly recently in the evolutionary span. Thus, they haven't had as much time to accumulate random mutations in their genetic codes.
