Which is known as ‘Terror of Bengal’?

Identify the organism which is a source of single cell protein and is grown on commercial scale.

Exposure to antigens, whether from living or deceased microbes or other proteins, prompts the host body to produce antibodies, resulting in active immunity. Active immunity operates gradually, requiring time to achieve its full effectiveness. The deliberate injection of microbes during immunization or the infiltration of infectious organisms into the body during natural infection induces active immunity. Conversely, when antibodies are administered directly to shield the body against foreign agents, it is referred to as passive immunity.
Which of the following is passive immunisation?

In which process unusual nucleotide (methyl guanosine triphosphate) is added to the 5' end of hnRNA.

Out of the following which one is not a hermaphrodite?

Read the passage and answer the question given below.
Exposure of a host to antigens, whether from living or deceased microbes or other proteins, triggers the production of antibodies within the host's body, resulting in what is known as active immunity. Active immunity operates gradually, requiring time to reach its full effectiveness. Introducing microbes deliberately through immunization or through natural infection allows for the induction of active immunity. Conversely, when antibodies are administered directly to shield the body against foreign agents, it constitutes passive immunity. Colostrum, produced by the mother during the initial stages of lactation, offers passive immunity due to its richness in antibodies.
