The best answer is c) trust me
Desert and steppe regions on Earth cover about 42 million square
kilometers, or about 30 percent of Earth's land surface
The percentage of energy in glucose that is available for the body to use is 40.6%.
<u>Explanation</u>:
Total used energy is the energy released by the hydrolysis of one mole of ATP and it is 30.7 kJ.
The total possible energy (used pus released as heat) is 2870 kJ.
Hydrolysis of 38 moles ATP gives = 38
30.7
= 1166.6 kJ of useful energy
The percentage of energy is transformed into useful energy, we can calculate by simple proportion,
2870 : 100 = 1166.6 : x
x = (1166.6
100) / 2870
x = 40.6% of energy is transformed into useful energy.
Answer:
what is the effect of food availability/competition on natural selection
Explanation:
Something along those lines, this is similar to the Galapagos finches when there used to be just one species but due to natural selection and limited food due to competition, the beaks changed to be able to eat the other food s available that they originally could not eat. There are now about 14 due to this.
I hope this helps u!
