Questionnaire Overview A questionnaire includes questions and other elements to elicit data suitable for the study. The questionnaire may be viewed as a paper-based interview. The creation of a questionnaire follows a structure similar to that of the interview schedule. However, due to the questionnaire’s impersonal nature, its development requires even more attention. Due to …
Phylum Coelenterata (Cnidaria) Definition: Phylum Coelenterata (Cnidaria) are defined as diploblastic metazoa having a nematocyst and a single gastrovascular cavity, or coelenteron, as the tissue construction grade. Phylum Coelenterata (Cnidaria) Characteristics They are aquatic, except for a few freshwater species, such as the hydra. They are multicellular and organized at the tissue level. They are …

Classification Of Bacteria On The Basis Of Nutrition All living creatures need nutrition since these ingredients are employed in biosynthesis and energy generation. Like all living cells, bacteria need food and energy to create proteins, maintain structural membranes, and power biochemical reactions. Sources of carbon, nitrogen, phosphorus, iron and a vast number of other chemicals …

Epithelial Tissue Definition One of the four kinds of tissue found in animals—the others being epithelial, muscular, connective, and nervous—epithelial tissue is made up of tightly clustered polyhedral cells that adhere strongly to one another to create cellular sheets that fill empty organs and coat the surface of the body. Epithelial tissue comprises cells arranged …

Phytoplankton Vs Zooplankton: An Overview Phytoplankton Definition The free-floating microalgae known as phytoplankton play a significant role in the ecosystems of the ocean, sea, and freshwater bodies of water. The terms “phyto” and “plankton,” which both imply drifter in Greek, are combined to form the word “phytoplankton.” Since phytoplanktons get chlorophyll to produce their own …

Biotic Factors Definition Ecosystem components include both biotic and abiotic elements. Abiotic factors include non-living substances such as radiation, sunshine, heat, water, soil, and humidity. These are the biotic factors that ultimately influence physical and chemical agents. The term “biotic factor” or “biotic components” refers to an ecosystem’s biological organisms. It is also to blame …
Differences Between Exotoxins Vs Endotoxins Toxins are small chemicals, peptides, or proteins created by living cells that, when they come into contact with or are ingested by tissues, can result in morphological changes or structural damage. Enzymes and toxins both contribute significantly to the pathogenicity of pathogenic bacteria. Toxins can promote invasiveness, harm cells, impair biological …
