The rainforests cover about 2 percent of the total area of the Earth surface but the 50 percent of the animals and plants of the earth live in the rainforest. The rainforests can be found in different countries of the world. These can be found in Alaska, Canada, Asia, America and Africa. The rainforest cannot be found in Alaska because the temperature in Alaska is too cold.
Answer:
Fish, shrimp prawns, crabs, shellfish and snails.
Others can be tigers, sharks, turtles, and many more.
if two doscounts x and y are given, then
total discount= (x+y-xy/100)%
by the question,
x=20%
y=75%
hence total discount= (20+75-20×75/100)%
=(95-1500/100)%
=(95-15)%
=80%
Why are we living longer now? Well during the Industrial revolution we made a significant reduction in the amount of deaths by increasing in food production and distribution, improving public health (mainly water and sanitation), and as for medical technology, we made vaccines and antibiotics. Modern medicine prospers every day, being able to cure almost any disease. Because of all of this we gradually started living longer. Back in 1950, life expectancy was 68.2 years old. Nowadays, that
number has risen to 79.12 years old and is expected to increase up to
83.9 years old by the year 2050.
