What sort evidence must be gathered to support the idea that all living things are composed of cells
a. comparison should be made between nonliving things in living things to determine any similarities in their structure
b. samples of many kinds of living things should be examined under a microscope to identify the presence of cells
c. the functions of cells are many different living things should be monitored to see if they are identical
d. nonliving things should be examined to verify that the smaller part is they are composed are not cells

In positive numbers less than 1, the zeros between the decimal point and a non-zero number are blank significant

While the change in blank will remain the same during a collision, the force needed to bring an object to a stop can be blank if the time if collision is blank

Abasketball star covers 2.65 m horizontally in a jump to dunk the ball. his motion through space can be modeled precisely as that of a particle at his center of mass. his center of mass is at elevation 1.02 m when he leaves the floor. it reaches a maximum height of 1.90 m above the floor and is at elevation 0.910 m when he touches down again. (a) determine his time of flight (his "hang time"). (b) determine his horizontal velocity at the instant of takeoff. (c) determine his vertical velocity at the instant of takeoff. (d) determine his takeoff angle. (e) for comparison, determine the hang time of a whitetail deer making a jump with center-of-mass elevations yi = 1.20 m, ymax = 2.45 m, and yf = 0.750 m.
