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.
Answer: Solute size
Explanation:
The passive process of filtration promotes the movement of solutes across the barrier. The smaller particles move more easily and the larger particles moves less easily or it can be said that the it needs energy to be transported.
The filtration of the solution having small solutes particles can be passed on from higher concentration to lower without the use of energy.
But the large particles needs more energy to move from one region to another.
The main difference between prokaryotes and eukaryotes is the nucleus.
Prokaryotes have it's DNA dispersed on the cytoplasm.
Eukaryotes have a differentiated nucleus where all the DNA locates and do all process.
So, the before and after "nut" could talk to you about the differentiation of this nucleus, rounded structure inside the cell with its wall.
Answer:
Additionally, see how survival of younger deer (fawns and yearlings) is reduced. Younger deer are the most sensitive to habitat quality and environmental events, thus reproduction and survival of fawns and yearlings can be a good indicator of habitat quality, or deer density relative to carrying capacity.
Explanation:
The fishapod is a 345 million old fish fossil that was discovered in the Canadian arctic in 2004.
