Base your answer to the following question on the graph below which shows the results of an experiment comparing the cooling rates of two cans of identical size and shape that painted different colors and filled with water at 100c the cans were allowed to cool at 60 minuets the temperature of the water in each can was recorded every 5 minuets describes the effect the color of the cans had on the cooling rate of the water during the first 10 minuets of the experiment ( answer fast)

According to the graph, we can see that the white cans cool a little bit slower than black cans on the same conditions.
On the first ten minutes, we can see that the temperature of water in black cans decreased from 100°C to 50°C. and the temperature of water in white cans decreased from 100°C to 75°C.
To explain this, you need to know what is a dark and white color?
it's a color in which the total absorption of all wavelengths and none of these wavelengths will be reflected. But since light is a form of energy expression, we can conclude that the black color has no energy on it. on the opposite of the white color, which absorbs all wavelengths, so it has energy on it (which will turn into heat), and that's why it could keep the temperature better than the dark color (all is about energy).

Are you asking about a street map usage  if so here is your answer  a street map for a very limited area could simply be a bit map or a .jpg image.  but a more general map would probably store the streets as vectors.  but you shouldn't assume that there is one way to do it

Amutation is basically the change in the gene, caused by alteration of single based units in the dna, or the genes or chromosomes were rearranged in the dna
