Some tissues, such as those in skin, are soft. Others, such as bone are harder. How do differences among cells explain this variation in tissue? a. Cell walls grow in hard tissues but not soft ones.
b. Smaller cells arise in softer tissue, while larger cells arise in harder tissues.
c. Cells die in harder tissues and then get pressed into dense solids over time.
d. Cells in one tissue perform a different function from cells in a different tissue.

Six solutions are made, each with a y concentration of 1.0 μm and varying concentrations of ab as shown below. based on the concentrations, rank the solutions in decreasing order of reaction rate.

Next a skier is pulled by a tow rope up a frictionless ski slope that makes an angle of 15 with the horizontal. the rope moves parallel to the slope with a constant speed of 0.69 m/s. the force of the rope does 800 3 of work on the skier as the skier moves a distance of 8.4 m up the incline. (a) if the rope moved with a constant speed of 2.2 m/s how much work would the force of the rope do on the skier as the skler moved a distance of 8.4 m up the incline? at what rate is the force of the rope doing work on the skier when the rope moves with a speed of (b) 0.69 m/s and (c) 2.2 m/s?

Suppose an objects initial velocity is 10m/s and it’s final velocity is 4 m/s. mass is constant. what can best be concluded about the object based in the work-energy theorem
