The gravitational potential energy of the ball decreases as it rolls down the hill while the gravitational kinetic energy of the ball increases due to its acceleration in velocity.
Hormones derived from amino acids can cause different effects in different cells depending on the type of cell and its signal transduction pathway.
An arrangement of chemical reactions in a cell that happens when a particle, for example, a hormone, joins to a receptor on the cell layer. The pathway is really a course of biochemical responses inside the cell that eventually achieve the objective particle or response.
Answer:
can you make the picture so that I can help you
The flow<span> of a </span>river<span> is the amount of water in the </span>river. ... Likewise, the steeper theriver's gradient<span>, the faster the </span>flow<span> of water (due to the pull of water down the </span>gradient<span>by gravity). Likewise, lower </span>gradients<span> would result in slower </span>flows<span> of the</span>river<span>.</span>
B is the answer to your question.
I hope this helped!
