My extremely heavy teacher desk is too massive to move. This resistance to change in motion is known as ______________
balance
inertia
gravitational resistance
potential
How does mechanical energy (total kinetic + potential) change as a diver drops off of a cliff?
it remains the same - kinetic energy just converts into potential energy during the fall.
it remains the same - potential energy just converts into kinetic energy during the fall.
it increases as the rock accelerates, some is converted to speed
it decreases as the potential energy converts to acceleration during the gravitational force of fall

In eukaryotic cells, this is the process of cell division that forms two new nuclei, each of which has the same number of chromosomes.
mitosis

A sea breeze blows from the ocean toward the shore. Why does this occur?
High pressure over the land causes a downdraft to occur.
Air over land heats faster than air over water, which causes convection.
The tide carries the wind to the shore as it moves back and forth.
Conduction of heat from the warm water produces wind from the ocean.
Which is a function of the respiratory system?
to provide the body with carbon dioxide, which reacts with food to produce energy
to provide the body with oxygen, which reacts with food to produce energy
to provide the cells with glucose, which is used as a source of energy
to provide the cells with water, which is used as a source of energy
How do forces act on a dropped object as it is falling?
Air resistance is pushing up on the object, while gravity is pulling it down.
Air resistance is pulling down on the object, while gravity is pushing it up.
Both gravity and air resistance are pulling down on the object.
Both gravity and air resistance are pushing up on the object.
