Animals use territorial behavior to adapt to new surroundings. it helps them stay stronger when they have to compete for food and it also helps with overcrowding and overpopulation
Based on what I have read. This is what you are looking for.
"During endothermic reactions, energy is absorbed from the surrounding environment.<span> The energy is typically transferred in the form of heat energy, and causes the reaction mixture and its environs to cool. A thermometer can be used to detect the decrease in temperature.</span>"
Answer:
(3a+2)/a(a+2)
Explanation:
(1/a)+(2/(a+2)
we cannot add any unlike fractions simply,we have to make it's denominator equal to add
you can do it by simply multiplication or by taking lcm of the the denominator!
here , it's 'a' and 'a+2'
now we got a modified denominator a(a+2), to make it fair to each term we have to multiply the extra multiplicand to numerator too
in case of 1/a, denominator becomes a(a+2) ,so we have to modify numerator also by multiplying the extra (a+2) to numerator also ,now 1/a becomes (a+2)/a(a+2)
---- similarly other term={2/(a+2)}can be modified as 2a/a(a+2)
now both denominator are equal , now new can add it simply by it's numerator
i.e, (a+2)/a(a+2) + 2a/a(a+2)
= (3a+2)/a(a+2)
it's from basic of fraction's addition!
