20. Jared's little sister asked him to explain how cells are similar in different organisms. Which comparison would best describe the similarities?
А
Playgrounds have different types of equipment and lots of different children playing. The way the children
share the equipment to play is similar to how cells share materials to live and grow.
B To make a building out of blocks, you have to have materials, a plan, someone to do the work, and somewhere
to put the extra blocks later. All cells work this way-food provides materials, the DNA provides the plan, and the
cell parts do the work and clean up.
с
The rooms of a house are like the parts of a cell. All houses have the same rooms that do the same things. Only
the shape and color of the houses are different, just like cells can have different shapes and colors.
To play a video game, you have to have a machine, a person to play it, a game cartridge, a power source, and
D sometimes accessories. Cells are the same way- they need to take in energy and cell parts and have different
roles based on the rules they are given.

Y=‐1x + 7 if y has a value of ‐24 what is the value of x?

Water is important for the of cells. a: size, shape, and temperature b: temperature, color, and odor c: color, odor, and size d: shape, temperature, and color

Nconcentration refers to the molar concentration of an ion in solution. it may be identical to, or greater or less than, the molar concentration of the compound containing the ion that was used to make the solution. for soluble salts, the molarity of a particular ion is equal to the molarity of that compound times the subscript for that ion. for example, 1 m of alcl3 is 1 m in al3+ and 3 m in cl−. 1 m of (nh4)2so4 is 2 m in nh4+ and 1 m in so42−. part a what is the concentration of k+ in 0.15 m of k2s? view available hint(s) nothing m m part b if cacl2 is dissolved in water, what can be said about the concentration of the ca2+ ion? view available hint(s) if is dissolved in water, what can be said about the concentration of the ion? it has the same concentration as the cl− ion. its concentration is half that of the cl− ion. its concentration is twice that of the cl− ion. its concentration is one-third that of the cl− ion. part c a scientist wants to make a solution of tribasic sodium phosphate, na3po4, for a laboratory experiment. how many grams of na3po4 will be needed to produce 550 ml of a solution that has a concentration of na+ ions of 0.700 m ? express your answer numerically in grams. view available hint(s) mass of na3po4 n a 3 p o 4 = nothing g provide feedback
