<span>They are both a form of passive transport, meaning that no cellular energy is required for the processes to take place.
They both involve the movement of materials from an area of high concentration to an area of low concentration.
The main difference is one of definition. When WATER is diffusing from one place to another, like across a membrane, the process is called OSMOSIS. The movement of any other substance is just called DIFFUSION.

Answer:
Answer is option C.
Mountain glaciers are the water reservoir that could always provide fresh water on earth.
Explanation:
Glacier, the largest fresh water reservoir on earth is an important component in the water cycle of earth. They are huge mass of ice formed over many years, where the accumulation of snow and ice exceeds ablation (melting and sublimation). About 69% of the world's fresh water is stored in glaciers. Glaciers are made from compressed snow, which is salt-free because it is formed from water vapor in the atmosphere. When the water evaporates, it left the salt behind. Also the pollution level of glaciers are very low compared to other water reservoirs like lakes, rivers, seas etc.
Answer:
A. The histone protein has fewer basic amino acids than albumin
Note: The question is incomplete. The complete question is given below:
You use the Bradford (coomassie) assay to determine the concentration of a whey protein. You use bovine albumin as your standard. You determine the histone protein concentration to be 3 mg/ml. When you use the same whey protein as your standard, you determine the histone protein concentration to be 5 mg/ml. Explain the discrepancy (pick ONE answer): (2 points) The histone protein has fewer basic amino acids than albumin. The histone protein has more acidic amino acids than albumin c. The histone protein has more basic amino acids than albumin d. The histone protein contains more methionine than albumin
Explanation:
The Bradford assay measures the concentration of proteins in a a protein sample using a color change that occurs from brown to blue when the protein in the sample binds to Coomassie dye. The Coomassie dye specifically binds to basic and aromatic amino acids in the protein. A standard curve is created using absorbance data from samples of proteins of known concentrations. The spectrophotometer is set to read at 595 nm in the Bradford assay as the peak absorbance of Coomassie Blue once bound to proteins occurs at 595 nm.
The higher the concentration of proteins, the higher the color intensity and the higher the absorbance values.
Since when bovine serum albumin was used as standard, the sample protein concentration was lesser than when the protein sample was used as standard, this means that the sample protein binds less to Coomassie dye as a standard thereby giving a higher sample protein concentration than the BSA standard. Therefore, the histone protein has fewer basic amino acids than albumin.
I'm not sure about this but I Think,Acyclovir halts viral DNA replication...You can ask someone higher educated to be sure
