Falling off at maturity. the process is controlled by the plant hormone auxin. as light levels and temperature drops, the flow if auxin to the leaves slows and the levels of other hormone, whenever, rise. this signals the cells at the vase of the leaf to weaken their cell walls , at the same time as other cells explains to break the connection between the weakened cells. the result is like tearing perforated paper and the leaf drops to the ground

When looking at your pictures in order, describe the changes to the area. What changes happened first? Why do you think that is?
Veronika [31]

Answer:

5. no i think that its the same as number 2 because based on number 2, at first there is climate change but then, flowers began to grow which is similar to the pictures protrayed in the website where at first forest trees are burned and then colonizing trees helped to change the landscape

hope this helps! :)

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.
