1.use the diagram to answer the question.
what would happen if some of the red blood cells were placed in beaker b?
water would move into the cells by osmosis, causing the cells to shrink.
water would move out of the cells by osmosis, causing the cells to shrink.
water would move into the cells by osmosis, causing the cells to swell.
water would move out of the cells by osmosis, causing the cells to swell
2.
use the diagram to answer the question.
what would happen if some of the red blood cells were placed in beaker a?
water would move into the cells by osmosis, and the cells would swell.
water would move out of the cells by diffusion, and the cells would shrink.
water would move out of the cells by osmosis, and the cells would shrink.
water would move into the cells by diffusion, and the cells would swell.
3.
what would occur if some of the red blood cells were placed in beaker c? recall that red blood cells normally float in plasma.
the concentration of water inside and outside the cells would be equal, so no osmosis would occur.
the concentration of water inside and outside the cells would be equal, so no diffusion would occur.
the concentration of water inside the cells would be less than outside, so the cells would swell.
the concentration of water inside the cells would be greater than outside, so the cells would shrink.
4.
what is a function of water in a cell?
producing lipids and carbohydrates
assisting in the production of proteins
the cell move and grow
preventing rapid temperature changes
5.
the cell membrane and water are both involved in
directing the cell’s activities and functions
the movement of materials into and out of the cell
preventing chemical reactions from taking place
making and packaging proteins for the cell

Industrial processes often require the damping of vibrations. consider a workbench that uses four large ideal springs in place of traditional legs, with each spring supporting one corner of the workbench and exhibiting a force constant of 47500 n/m. this workbench is used when creating products that involve highly unstable chemicals. according to specifications, the acceleration of the manufacturing equipment must be held to less than 22.3 m/s2 for the manufacturing process to proceed safely. the amplitude of vibrations are expected to remain under 0.622 mm throughout. given that the workbench and maufacturing equipment combine to 6.05 kg, find the maximum acceleration expected of the equipment and workbench. (ignore the mass of the springs.)
