Which of the following is the correct sequence of taxonomic hierarchy from lowest to highest? MCQ with Answer and Explanation

Explanation:
Basophils, and similarly mast cells in tissues, release histamine and other inflammatory mediators during allergic and hypersensitivity reactions. Neutrophils are first responders to infection, lymphocytes are adaptive immune cells, monocytes become macrophages. Histamine causes vasodilation and bronchoconstriction.

Explanation:
The pancreas is a mixed gland: exocrine acini secrete digestive enzymes (trypsin, lipase, amylase) into the duodenum, while endocrine islets secrete insulin and glucagon into the blood. The liver produces bile, not digestive enzymes. Spleen filters blood, gall bladder stores bile.

Explanation:
Phycology (algology) is the study of algae, which are photosynthetic eukaryotic organisms ranging from unicellular to multicellular forms. Mycology deals with fungi, bryology with mosses and liverworts, and pteridology with ferns. Algae include green algae, red algae, brown algae, and diatoms, and are important primary producers in aquatic ecosystems.
