Two angles are called complementary angles, if their sum is one right angle i.e. 90°.
Each angle is called the complement of the other.
Example, 20° and 70° are complementary angles, because 20° + 70° = 90°.
Clearly, 20° is the complement of 70° and 70° is the complement of 20°.
Thus, the complement of angle 53° = 90° - 53° = 37°.

Tropical Evergreen Forests: These forests are also called the tropical rainforests. These forests are found in the regions near the equator and close to the tropics. These regions are hot and receive plenty of rainfall throughout the year. Since rainfall is throughout the year, there is no particular dry season. Hence the trees do not shed their leaves altogether and the trees always appear green. This is the reason they are called evergreen.The trees are closely spaced. Thick canopies of these closely spaced trees do not allow sunlight to penetrate inside the forest even in day time. The following hardwood trees are common here; rosewood, ebony, mahogany, etc.

» 2x + 3y + 5 = 0
» kx + 4y = 10
➡ kx + 4y - 10 = 0
we have to find the value of k such that the pair of equations have unique solution.
we know that, when pair of equations have unique solution,
a1/a2 ≠ b1/b2
➡ 2/k ≠ 3/5
just put any value of k so that it doesn't get equal to 3/5.
you can put 1, 2 etc.
for example, k is 2, then a1/a2 = 2/2 = 1
LHS ≠ RHS

Cellular respiration is a characteristic of all living cells in organisms. It is a catabolic process in which reduced substrates are oxidised to release energy and synthesize biochemical intermediates. In aerobic respiration, oxygen is utilised by the organisms to indirectly break down nutrient molecules like glucose and to derive energy for performing various activities. Carbon dioxide which is harmful is also released during the catabolic reactions.
