Answer:
An animal that is getting body heat.
<span>Oil and water don't mix because oil is made up of non-polar molecules while water molecules are polar in nature. Because water molecules are electrically charged, they get attracted to otherwater molecules and exclude the oil molecules. (this is from wiki)</span>
<u>Al2(SO4)3</u>
<u>Option: E</u>
<u>Explanation:</u>
The freezing point lowering of a solution depends on the number of ions and molecules that dissolve in water solution. So when there are more number of molecules, the freezing point will also be reduced more.
Now let us look at Al2(SO4)3. Here, it produces a total of 5 molecules. i.e (2 Al(3+) and 3 SO4(2-)). If we take the other choices from first:
MgBr2 - It produces a total of 3 molecules. (1 Mg(2+) and 2 Br(-))
HOCH2CH3 - This produces 1 molecule as it remains the same as HOCH2CH3 because it is covalent and does not dissociate in water.
NaNO3 - This produces 2 molecules. (1 Na(1+) and 1 NO3(-))
C6H12O6 - This also produces 1 molecule same as HOCH2CH3 because it is also covalent and does not dissociate in water.
Na3PO4 - This produces a total of 4 molecules. (3 Na(+) and 1 PO4(3-))
Thus, from the above analysis, it shows that Al2(SO4)3 has more molecules compared to others. When there are more molecules, the freezing point is also lower.

Bacteria multiply through binary fission. This process involves the division of a single cell into two identical daughter cells, and it starts when the DNA of a bacterium divides into two replicates. The bacterial cell splits into two daughter cells that have identical DNA to the parent cell.
