21) The X hypothesis, proposed by JamesLovelock, was first scientifically formulated in the1960s by Lovelock as a consequence of his work

for NASA on methods of detecting life on Mars.

It is an ecological hypothesis proposing that thebiosphere and the physical components of the

Earth (atmosphere, cryosphere, hydrosphere andlithosphere) are closely integrated to form acomplex interacting system that maintains theclimatic and biogeochemical conditions on Earth

in a preferred homeostasis.It was named after the Greek supreme goddess ofEarth. The theory was initially, said to be a wayto explain the fact that combinations of chemicalsincluding oxygen and methane persist in stable

25) The simplest method to measure temperatuethis way is to count the number of_____in 15seconds and add 40. The sum usually approximates

the temperature within a few degrees Fahrenheit.

The original formula for determining temperaturefrom____appears to have been published in 1897

by A.E. Dolbear, a physics professor at Tufts College.Since Dolbears time, formulas have been devisedfor various sub-species. For example:

Field ______: T = 50 + (N - 40 / 4)

Snowy Tree _______: T = 50 + (N - 92 / 4.7)

Katydid: T = 60 + (N - 19 / 3)
