CHILD DEVELOPMENT PEDAGOGY

Detailed explanation-1: -Biosafety level 2 (BSL-2) covers all laboratories that work with agents associated with human diseases-that is, pathogenic or infectious organisms-that pose a moderate health hazard.

Detailed explanation-2: -There are six levels of cognitive learning according to the revised version of Bloom’s Taxonomy. Each level is conceptually different. The six levels are remembering, understanding, applying, analyzing, evaluating, and creating.

Detailed explanation-3: -There are four biosafety levels. Each level has specific controls for containment of microbes and biological agents. The primary risks that determine levels of containment are infectivity, severity of disease, transmissibility, and the nature of the work conducted.

Detailed explanation-4: -Activities and projects conducted in biological laboratories are categorized by biosafety level. The four biosafety levels are BSL-1, BSL-2, BSL-3, and BSL-4, with BSL-4 being the highest (maximum) level of containment.
