The answer is; A
This model hypothesizes how life started during the early conditions of the earth which were hot and filled with greenhouse gases in its atmosphere about 4 billion years ago. It is explained by the theory of spontaneous generation where organic molecules were created from inorganic molecules spurred from energy from lightning. These organic molecules filled the water bodies and chemically arranged themselves, over time, into primordial life.
It would drop you pH levels in your body prior to eating. When you eat the burger it will bring it back up, hopefully to 7 (neutral)

Answer: Cell number one is an hypotonic solution, cell number two is an isotonic solution, and cell three is an hypertonic solution.
Explanation:
Cell number one which is a 98% water content is added the 100% water solution, water moves from low to high concentration. Therefore, the water moves from the solution into the cell, which is hypotonic.
Cell number two which is a 98% water content added with a 98% water solution. These two solutions are equal to one another, so the water does not move. This is isotonic.
Cell number three which is a 98% water content added with a 80% water solution. Water moves from high to low concentrations, so water moves from the cell to the solution. The water leaves the cell, which is an hypertonic.
