By copying their genomes, they retain the tool kit and at the same time generate a garage full of spare parts. Gene duplication can provide the raw material for expression changes to occur, and polyploidy itself can trigger epigenetic changes
current, the flow of electrons make the current
The rate of change of d(t) at t = 2 and t = 6 is the ratio between the change of distance (difference between the distances) to the time elapsed. That is,
r = (576 - 64) / (6 - 2) = 128 ft /s
The rate of change is equal to 128 ft/s and this represents the average speed at this time interval.
Answer:
There is a right angle and it has three sides.
Explanation:
There are two 45 degree angles and since a triangles sides ALWAYS add up to 180 we know the the other side has to be 90 degrees because 45+45+90=180. And we know that every triangle has three sides because "tri" means three.
Heat absorbed to raise the temperature is given by
here
m = mass
c = 7.11 J/g C
Q = 138 KJ
Now by using the above formula we will have
So the amount of the substance will be 3.88 kg
