What function does the cytosol do in a cell?
semifluid medium of a cell's cytoplasm.The cytosol has no single function and is instead the site of a wide variety of cell processes. Examples of these processes include signal transduction from the cell membrane to sites within the cell, such as the cell nucleus,[51] or organelles.[52] This compartment is also the site of many of the processes of cytokinesis, after the breakdown of the nuclear membrane in mitosis.[53] Another major function of cytosol is to transport metabolites from their site of production to where they are used. This is relatively simple for water-soluble molecules, such as amino acids, which can diffuse rapidly through the cytosol.[14] However, hydrophobic molecules, such as fatty acids or sterols, can be transported through the cytosol by specific binding proteins, which shuttle these molecules between cell membranes.[54][55] Molecules taken into the cell by endocytosis or on their way to be secreted can also be transported through the cytosol inside vesicles,[56] which are small spheres of lipids that are moved along the cytoskeleton by motor proteins.[57] The cytosol is the site of most metabolism in prokaryotes,[6] and a large proportion of the metabolism of eukaryotes. For instance, in mammals about half of the proteins in the cell are localized to the cytosol.[58] The most complete data are available in yeast, where metabolic reconstructions indicate that the majority of both metabolic processes and metabolites occur in the cytosol.[59] Major metabolic pathways that occur in the cytosol in animals are protein biosynthesis, the pentose phosphate pathway, glycolysis and gluconeogenesis.[60] The localization of pathways can be different in other organisms, for instance fatty acid synthesis occurs in chloroplasts in plants[61][62] and in apicoplasts in apicomplexa.[63]http://en.wikipedia.org/wiki/CytosolTo suck the sperm and urine out of the dickthe function is to save the cell from dirt and germs.
What is a lipid that contains phosphorus and that is a structural component in cell membranes?
Our world has a lot of phosphorus in it. There are two different kinds of phosphorus, which includes man-made phosphorus and natural phosphorus. The phosphorus in our teeth, nails, and body fluids is natural. Other phosphorus in highlighter ink, laundry detergent, and televisions screens is man-made. All of these things will show under a black light.
Why does cell membrane not leak when its is punctured with a needle?
If a cell is punctured with an ultra-fine needle it will NOT leak. instead, the proteins and phospholipids will move in to fill the gap as the needle is removed.
Why is the model of a membrane shown in the transperency referred to as the fluid mosaic model?
The membrane is made out of several molecules - mainly phospholipids. Instead of being a rigid structure, the molecules within the membrane are constantly moving and changing places. This means the membrane appears like a fluid.
Why must scientists be ethical about their work?
If they didn't, they would be lying and instead of trying to help others, they would be just pleasing themselves.
A form of diffusion in which the molecules pass through a protein instead of between the phospholipids is called?
Glucose molecules are molecules that pass through a protein instead of between the phospholipids. This is because they are to big to diffuse through phospholipids.
What do animal cells have instead of a cell wall?
A membrane composed of phospholipids. Called the phospholipid bilayer, it's two phospholipids with their "heads" facing opposing directions and their "tails" facing inward. They have a natural tendency to come together in a spherical shape and they pack themselves in relatively tight together, through differences in polarity of the tails of the phospholipids against their surroundings.
Which kingdoms do not have a cell wall?
The eukaryotic Cells have an extracellular glyco-callyx coat instead of the bacterial Cell Wall.
What is a function of a Cytosol?
Cytoplasm is stored in an animal or plant cell and its job is to store nutrition and important chemicals for the cell. The Cytoplasm also provides support for the cell and allows movement in a cell but does not move anything.
What do otters have instead of blubber?
Instead of blubber, the otter species keep themselves warm by growing a dense fur coat.
What are some fan coral adaptations?
not sure if this is one but they anchor themselves in mud or sand instead of attaching themselves to hard substrates.

Do oceans produce sugar instead of salt?
Oceans of and by themselves produce neither.
Do donkeys pant?
equines are incapable of panting and instead sweat to cool themselves down
What course was open to the pilgrims when they found themselves in cape cod instead of Virginia?
no restrictions on them
Should animals be left in the wild instead of being placed in the zoo?
In the wild because they can be free and they can take care of themselves and find food by themselves.
