Which property of water prevents significant changes in its temperature even when heat is lost or absorbed in the environment?

Categorize the following processes as Anabolic or Catabolic:
$I -$ Protein synthesis,
$II -$ Lactic acid fermentation,
$III -$ Aerobic respiration,
$IV -$ Alcoholic fermentation,
$V -$ Synthesis of cholesterol from acetic acid,
$VI -$ Photosynthesis,
$VII -$ Digestion,
Identify the Anabolic and Catabolic processes respectively.

Match the following columns:

Column-$I$	Column-$II$
$1$. Oleate	$a$. Triose sugar
$2$. Trihydroxy alcohol	$b$. Unsaturated fatty acid
$3$. Glyceraldehyde	$c$. Subcutaneous fat layer
$4$. Amylopectin	$d$. Glycerol
$5$. Ergosterol	$e$. Branched chain of glucose units

The smallest particle of water is

Match the names of biomolecules listed under column $I$ with the characteristics given under column $II$; choose the answer which gives the correct combination of the alphabets of the two columns.

Column-$I$ (Biomolecule)	Column-$II$ (Characteristics)
$(A)$ $ATP$	$(p)$ One or more sugar monomers
$(B)$ $DNA$	$(q)$ The main source of energy
$(C)$ Protein	$(r)$ Two strands of nucleotides
$(D)$ Carbohydrate	$(s)$ Long sequence of amino acids

In the given figure,what does $A$ indicate?
