At the time of this writing, the most recently available statistics pertain to 2010, at which point the World Bank reported that about 37.7 percent of the world's total land area was considered agricultural land, while approximately 10.6 percent was considered arable.
To catch them :) hope this helps
The scientific investigation is the systematic approach of the scientists to answer the questions about the world. It is applied almost all of the theories including the Theory of Natural Selection. Darwin's theory of evolution is a result of scientific investigation. In this theory, they investigate by observing the distribution of species.

<em>Hello there?</em>
In the stomach, hydrochloric acid is present which is a strong acid (0-4) which is below pH 7. Therefore an enzyme that act best well here should be below pH 7 which for our case is A.

Answer:
The question lacks options, the options are;
A) 4 KJ
B) 122 KJ
C) 30.5 KJ
D) 1600 KJ
The answer is B, 122KJ
Explanation:
Adenosine triphosphate (ATP) is the energy currency of all living cells. It is the usable form of energy by cells for their life functions. Energy in ATP is harnessed via the hydrolysis of one of its phosphate molecules to form Adenosine diphosphate (ADP). The energy (measured in Kilojoules) needed by cells is released in this process.
In this case, a cell uses energy to pump hormones into the bloodstream. According to the question, 4 ATP's were used i.e. 4 ATP were converted to ADP. The hydrolysis of one ATP molecule releases 30.5 KJ/mol of energy needed for cellular work.
Hence, if 4 ATP were utilized by this particular cell, 4 × 30.5 KJ = 122 KJ of energy will be used by the cell to pump hormones.
