1/4. There is a 1/2 chance for each plant to pass on a gene for wrinkled seeds, and both must pass the gene, so we have 1/2*1/2=1/4.

In which case would facilitated diffusion be needed?
melomori [17]

Answer:

The voltage-gated potassium channels associated with an action potential provide an example of what type of membrane transport?

A. Simple diffusion.

B.<u> Facilitated diffusion. </u>

C. Coupled transport.

D. Active transport.

You are studying the entry of a small molecule into red blood cells. You determine the rate of movement across the membrane under a variety of conditions and make the following observations:

i. The molecules can move across the membrane in either direction.

ii. The molecules always move down their concentration gradient.

iii. No energy source is required for the molecules to move across the membrane.

iv. As the difference in concentration across the membrane increases, the rate of transport reaches a maximum.

The mechanism used to get this molecule across the membrane is most likely:

A. simple diffusion.

<u>B. facilitated diffusion. </u>

C. active transport.

D. There is not enough information to determine a mechanism.

Carrier proteins - exist in two conformations, altered by high affinity binding of the transported molecule. Moves material in either direction, down concentration gradient (facilitated diffusion). EXAMPLE: GluT1 erythrocyte glucose transporter.

Channel proteins - primarily for ion transport. Form an aqueous pore through the lipid bilayer. May be gated. Moves material in either direction, down concentration gradient (facilitated diffusion). EXAMPLES: Voltage-gated sodium channel, erytrhocyte bicarbonate exchange protein.

This might be helpful... because I don't know anything about facilitated diffusion.

If you are testing traits for Mendelian inheritance, how do you calculate the EXPECTED values?
Georgia [21]

n a cross between two heterozygous individuals, the offspring would be expected to show a 3 : 1 ratio. For example, in Case 1, three-fourths of the individuals would have red (wild-type) eyes, and one-fourth would have sepia eyes.

If there are 44 offspring, how many are expected to have red eyes?

We expect three-fourths to have red eyes.
<span>34</span> of 44 = 33

If there are 44 offspring, how many are expected to have sepia eyes?
<span>14</span> of 44 = 11

Now you are ready to calculate chi-square.
