D. Scavengers.
Step-by-step explanation:
Explanations are ordered from answers (coordinated)
18. The question asks which of the given options is not a chemical approach to control microorganisms. Antibiotics, disinfectants, and antiseptics are all chemical approaches that can be used to control microorganisms, while autoclaving is a physical method that uses high pressure and high temperature to sterilize materials.
The scientific name for modern man, or Homo sapiens, is option B.
Prokaryotic organisms, which lack a membrane-bound nucleus and other complex cell structures, are placed in the kingdom Monera. The other options given, Fungi, Protista, and Plantae, are all eukaryotic kingdoms.
Angiosperms are plants that have true roots, leaves, stem, and seeds inside a fruit. Gymnosperms, ferns, and mosses are other types of plants with different characteristics.
Taxonomic groups are organized hierarchically, with closely related organisms grouped together at lower levels and more distantly related organisms grouped at higher levels. The options given, genus, order, class, and phylum, are all taxonomic ranks, but genus is the level that contains closely related organisms.
Plasmodium is a single-celled parasitic protozoan that causes malaria. Paramecium is a different type of single-celled organism, while Salmonella is a type of bacteria and mosquito is an insect.
Yeast, molds, and mushrooms are all eukaryotic organisms that belong to the kingdom Fungi. Ecosystem and population are not kingdoms, but rather ecological concepts that describe interactions among different organisms in an environment.
Ecology is the scientific study of the interactions between organisms and their environment. The options given, organism and none, are not part of the field of ecology.
Consumers are organisms that obtain energy by consuming other organisms. Photosynthetic bacteria and green plants are autotrophic organisms that produce their own food through photosynthesis, while chemosynthetic bacteria obtain energy from chemical reactions. Scavengers, like vultures or hyenas, are examples of consumers that feed on dead organisms.
