I think you wrote this wrong? Is it not round rr vs wrinkled RR?? I'll answer it with that assumption:
You are crossing a rr with an RR:
You only get Rr back so they will phenotypically be all wrinkled
If you are crossing rr with an Rr (so a heterozygote wrinkled):
50% will be Rr (wrinkled)
50% will be rr (round)
See my picture for the Punnett Squares for both answers!
There are mountain ranges in the middle of the ocean floor. Because of the higher elevation gravity pushes down on the edges of the plates. This is called ridge push.
<h3><u>Explanation:</u></h3>
Ridge push is a simple explanation of the height of the landforms based on the gravity and the elasticity of the underlying rock. It says when a landform gets too much higher, the weight of the overlying rock and soil pushes the landform back to plains. Thereby an equilibrium is maintained.
Slab pull is a theory proposed which visualizes the earth interior as a pool of hot molten lava that has a convection current going on. It explains why the crust of the earth continuously moves slowly and forms mountains and other rift valleys.
There are called the stomata
Natural selection is a mechanism of evolution. Organisms that are more adapted to their environment and are more likely to survive and pass on the genes that aided their success. This process causes species to change and diverge over time.
Hope this helps :))
I don't completely understand the question, but I am guessing that you are trying to finish the sentence. If so, the answer is "Diffusion continues until the concentration on both sides of the membrane is <u>equal</u>". The reason it's equal is because diffusion always travels high to low, to reach a point of equilibrium. The particles are trying to move so that water is the same inside and outside of the cell/membrane, and the solute is also equal on the inside and outside of the cell/membrane. If that doesn't make sense, just comment any questions you have and I will try my best to answer :)
