Carlos uses one golf ball to set another golf ball in motion. The following diagram
shows how Carlos designs his experiment.
Carlos releases the ball on the string from
different heights. Each time, the first ball
strikes the second ball, which then rolls
down the track. Which force causes the
first ball to swing downward?
A a pull due to gravity
(B a pull from the string
© a push from Carlos's hand
D friction between air and the golf ball
which force causes the first ball to swing downward?

interphase   is the cell cycle stage in which the cell acquires nutrients, creates and uses proteins and other molecules and starts the process of cell division by replicating the dna. it is the longest stage in the eukaryote cell cycle.

the following   can go wrong during interphase:   a base pair could be mismatched during the duplication process causing a mutation.   correct answer: c

explanation:

micro/nanoscale topography surface exhibits many prominent properties and is extensively employed in biomedical device, microfluidic device and energy device fabrication. additionally, the clinical applications of biomaterials can be largely expanded with of nanostructured surfaces.

stimulus is a change in the environment that causes an organism to react. the response is the reaction to the stimulus. some examples of stimuli for zebras are drought, to many predators, and bad feeding grounds such as dead grass or plants. zebras respond to stimuli just like all other living organisms
