Oxygen is a small molecule and it's nonpolar, so it easily passes through a cell membrane. Carbon dioxide, the byproduct of cell respiration, is small enough to readily diffuse out of a cell. Small uncharged lipid molecules can pass through the lipid innards of the membrane.
The nucleus potentially resembling an egg yolk, the main component of a cell. The white of the egg would be the gel inside the cell, can't remember the name of it?
Fungi is what decomposes things and puts nitrogen back into the ground. without the fungi plants would soon begin to run out of the nutrients they need. lack in vegetation would soon form. animals would then start to die of or migrate to different locations. so eventually you would begin to see less food and more wildlife in town because of the food shortage.
The appropriate response is cilia. Cilia are little hair-like structures on the surface of the cell. The hairs clear hair, bodily fluid, caught tidy and microscopic organisms up to the back of the throat where it can be gulped.
Cilia are found in the coating of the trachea (windpipe), where they clear bodily fluid and earth out of the lungs. In female well evolved creatures, the beating of cilia in the Fallopian tubes moves the ovum from the ovary to the uterus.
Gouges made by ice sheets are erosion.
