<h3>Answer:</h3><h2>A Reaction is the rate rate which increases with a decrease in temperature.</h2>
It can be physical or chemical; a physical reaction is the one which occurs as a result to an event i.e. anger, happiness, excitement etc. Where as a chemical reaction is illustrates the process a chemical behaves when mixed with another substance.
Explanation:
1.Law of Inertia
<em>Inertia</em><em> </em>: is the ability to resist change in motion.
<em>Example</em><em>;</em><em> </em><em>if you roll a ball it will keep running unless you</em><em> change </em><em>it's</em><em> </em><em>direction with the help of </em><em>friction.</em><em>.</em>
2. second law of motion states that an object will accelerate when an unbalanced force is applied on a mass..
<em>unbalanced force is a type of force</em><em> where total force</em><em>≠</em><em>zero</em><em>,</em><em> </em><em>means the object will move</em><em>.</em><em>.</em>
<em>Example</em><em>;</em><em> if you will try to push a truck</em><em> will be less but if you push a car the acceleration will be more</em><em>.</em><em>.</em><em> because </em><em>c</em><em>ar has less </em><em>mass.</em><em>.</em>
<em>3</em><em>.</em><em> the third law of motion state that foreign every</em><em> action there is a opposite reaction</em><em>.</em><em>.</em>
<em>Example</em><em>;</em><em> can you throw a ball on the floor </em><em>.</em><em>.</em><em>.</em><em>the floor </em><em>pushes</em><em> </em><em>back</em><em> that the ball</em><em>.</em><em>.</em>

Stem cells are very controversial for several reasons. Mainly, because stem cells need to be harvested from Embryos, which raises a huge ethical debate as to weather the (scientifically speaking, alive) embryo harvesting is not cruel and twisted, as these are human beings that are being used. Another ethical issue is that it is related to human cloning, and often times stem cells are mislabeled. Not to mention that there is an argument for the idea of cloning humans to be used for limb replacement, throwing everybody in a tizzy. Overall, one of the greatest medical acheivements of recent years has lots of issues that haunt it.
