What is the relationship among cells, chromosomes, genes, and dna? a. dna is a double helix structure found in the nucleus. chromosomes straighten out the dna so the code can be read by genes. b. cells contain chromosomes which are made up of genes. genes are made up of tightly wound strands of dna. c. chromosomes are tightly wound strands of dna located in cells. genes are sections of dna. d. tightly wound strands of chromosomes contain genes and are found in cells. the genes we coded sequences nucleotide read by dna.

The diagram below shows a cell placed in a solution. a cell is shown placed inside a beaker. it is labeled cell. the solution inside the beaker is labeled 40% salt solution and the solution inside the cell is labeled 20% salt solution. only water is allowed to move in and out of the cell. what will most likely happen to the cell? it will expand as water moves out of it. it will shrink as water moves out of it. it will expand as water moves into it. it will shrink as water moves into it.

The molality of calcium chloride (cacl2) in an aqueous solution is 2.46 m. what is mole fraction of the solute?

The small bags of silica gel you often see in a new shoe box are placed there to control humidity. despite its name, silica gel is a solid. it is a chemically inert, highly porous, amorphous form of sio2. because water vapor readily adsorbs onto the surface of silica gel, it acts as a desiccant. despite not knowing mechanistic details of the adsorption of water onto silica gel, from the information provided you should be able to make an educated guess about the thermodynamic characteristics of the process. predict the signs for δg, δh, and δs for the adsorption of water.
