Basics in Engineering Biology : Practice MCQ Questions & Answers with Explanations

Individuals with fundamental similarities are known as species. Genus comprises of group of related species which has more characters in common in comparison to species of other genera. Kingdom is the ultimate and most superior hierarchy which holds the group of related phylum.

He accidently dropped a mixture of rubber and sulfur on a hot stove and found the mixture to be flexible and tough led to the discovery of vulcanization process. The other processes mentioned aren't a part of his discovery. Polymerization is addition of monomer units, Liquefaction is conversion of a solid to liquid, and Sublimation is the direct conversion of solid to gas.

Publishing for cross check is not an approved step by biologists in fact the step that is approved and similar to cross check is confirming, modifying, or rejecting the hypothesis. All others mentioned are the approved steps in the classification of organisms.

Fungi are generally either parasitic or symbiotic in nature. Hence they obtain their food from the host organism or the organism with which they hold a symbiotic relationship. They are unicellular eukaryotes and structurally they are made up of individual feathery filaments called hyphae.

Monera consists of unicellular organisms that lack a nucleus and many of the specialized cell parts, called cell organelles. Hence they are termed to be prokaryotic. Monera mainly constitutes of bacterial organisms. All others mentioned are either unicellular or multicellular eukaryotes.

Pieces is a class in the subphylum vertebrata under the phylum chordate while all others mentioned are the names of 5 kingdom classes. The others i.e. monera, protista and plantae are the 5 kingdom classification hierarchy.

Taxonomy is the branch of science dealing with the classification of organisms, specially with systematics. Nomenclature is the naming of organisms according to their genus and specific epithet. Specialization and bioautonomy aren't the terms used in the naming and classification of the living world.

Evolution always involves continuous development and modifications in all aspects and not only in specific aspects such as genetic, biochemical etc. Subsequent, biological and genetic modifications are just parts of the overall continuous modifications.

Movement can occur in non-living organisms under the influence of high speed winds, high water current, pressure etc. Hence it cannot be considered as an exclusive characteristic to living organisms. Growth, reproduction, consciousness are considered as characteristic features because no non living organism can produce one of its kind by own, show metabolic changes or show signs of being conscious.

A living organism is defined as a complex entity of physiochemical components that is capable of surviving through self-regulatory mechanisms such as metabolism, reproducing, and coping with the external environment.
