B. the second part of meiosis is very similar to mitosis
The solution is non-ideal for NaCl soln so ΔH3<span> is greater than the sum of ΔH</span>1<span> and ΔH</span>2. this means the forces of attraction between like molecules is greater than the forces of attraction between unlike molecules. <span>NaCl (table salt) dissolves readily in water. In solid NaCl, the positive sodium ions are attracted to the negative chloride ions. The same is true of the solvent, water; the partially positive hydrogen atoms are attracted to the partially negative oxygen atoms. While NaCl dissolves in water, the positive sodium cations and chloride anions are being stabilized by the water molecule electric dipoles. Thus, the intermolecular bonds between NaCl are broken and the salt is dissolved.</span>
The four (4) functions of water in the body are:
I. Site for many reactions.
II. Transport of nutrients and wastes.
III. Carries heat.
IV. Acts as solvent.
Water can be defined as a liquid molecule that comprises two (2) main chemical elements, which are hydrogen and oxygen in the ratio of two to one (2:1).
Generally, water is considered to be an important and essential chemical molecule that aids in the growth and development of the body of living organisms. The four (4) functions of water in the body of a living organism are:
- It is typically a site for many reactions.
- It helps in the transportation of nutrients and wastes around the body.
- It carries heat from a hot region.
- It acts as solvent to dissolve a solute to produce a solution.
