(1) This kingdom comprises of Eukaryotic organisms that are mostly unicellular with some exceptional multicellular algae. Amoeba , Euglena and Paramoecium all belong to the kingdom Protista of gwhittaker’s 5 kingdom classification system. This kingdom includes all the unicellular eukaryotic organisms.
(2) Hepatitis is the odd one out because it is a type of viral infection while the rest of three are spread through the bite of mosquitoes.
(3) Neutralisation is the reaction between an acid and a base to form a salt and water. Some examples of neutralisation reaction are as follows. During neutralisation reaction, hydrogen ions from acid react with hydroxide ions from alkali to form water. H + (aq) + OH – (aq) → H 2 O (aq)
(4) Lactobacilli are not harmful bacteria. They are mostly found in the gastrointestinal tracts of humans and animals. They are an important component of dairy products such as milk, yogurt, ghee, etc.
(5) positive terminal of a dry cell is cathode
