Geothermal Energy and Solar Energy
Answer:
Through simple diffusion, down the concentration gradient.
Explanation:
The phospholipids of the membrane are amphipathic with hydrophillic heads and hydrophobic tails. Other polar molecules cannot go through this hydrophobic interior. Since small uncharged lipids are non polar and hydrohobic, they are able to go through the membrane without the help of transport proteins. Therefore, the last two options can be ruled out because facilitated diffusion includes the use of a protein. Diffusion involves molecules moving down the concentration gradient so the second option can be ruled out.
Photosynthesis is when plants turn light from the sun into food (energy). The light from the sun is turned into energy by using chlorophyll. Chlorophyll absorbs blue and red light to turn Co2 and H2o into glucose.
The goal is to selectively develop specific desired characteristics in plants or animals, eventually creating the desired offspring.
Your answer would be A because none of the others make sense, Hope that helps!
