The media plays a very important role as a source of information,education and entertainment, whether it is radio, movies or TV. It accommodates the world in to a single village which is saturated of media-information, that cause us to wear what we do, drink what we drink and eat what we eat.
The time it takes in milliseconds for the brain to transmit a signal to your skeletal muscles can be determined given the speed and distance. It was given that the signal travels at approximately 25 m/s while the distance between the brain and one' hand can be set to approximately 1 m. To obtain the time, we divide the distance by the speed and convert it to milliseconds.
The equation would be: (1 m/ 25 m/s)*(1000 ms/1 s) = 40 ms.
Thus, it will take 40 ms for the brain's signal to travel before it can command your skeletal muscles to react accordingly.
Answer:
from what i read!! use own words
Explanation:
Fracking can contaminate water supplies if it is not done properly, because the fracking fluid injected into rock to enable gas to be released often contains chemicals. ... The other possibility of pollution is when the water, which is mixed with chemicals and sand for the fracking process, comes back to the surface
Does fracking contaminate water?
No. They gave examples where fracking could contaminate water. For instance they state that "Injection of hydraulic fracturing fluids directly into groundwater resources" can cause contamination. ... The EPA also notes that disposing of fracking wastewater directly into surface water could contaminate drinking water.
Answer:
predictions is the correct answer.
Explanation:
- Scientific models must be able to generate predictions.
- Scientific models refer to a conceptual illustration of a method of concepts, events or methods which are utilized to explain and predict the role of a system.
- Scientists normally use Scientific models to carry out study and to describe the outcomes of their analysis.
- A reliable and efficient scientific model should be adequate to make perfect predictions.
Mutation
is random, natural selection isn't random because those mutations which
are most adaptable to the environmental conditions of the time are
those which produce more offspring. I mean, "selection", by definition,
isn't "random". <span>The
clue is in the title. It's not considered random for the simple reason
that it's not random. Natural selection is an extremely deterministic
process. So, i guess it's (D) Natural Selection
