Example: Adenosine triphosphate energy molecule.
(c) There are five groups given below with four examples in each. In each group, there is one example which does not fit into the category. For each of these groups write down the category of the group and identify the odd one as shown in the example below:
i. Diplococcus, Salmonella typhi, Plasmodium, Vibrio cholera.
ii. Adrenal, Liver, Thyroid, Pituitary.
iii. Coughing, Sneezing, Eating, Blinking.
iv. Corpus luteum, Corpus callosum, Pons, Cerebellum.
v. Sulphur dioxide, Carbon monoxide, Oxygen, Nitrogen dioxide.
Sl. No (i) has been done for you as an example. Example Sl. No. Category Odd one (i) Disease causing bacteria Plasmodium.
