In biology, homology is similarity due to shared ancestry between a pair of structures or genes in different taxa. A common example of homologous structures is the forelimbs of vertebrates , where the wings of bats and birds , the arms of primates , the front flippers of whales , and the forelegs of four-legged vertebrates like dogs and ...
The release of one species to control another (Carlton 2001). The management of weeds using introduced herbivores (often insects) as biological control agents (Booth et al. 2003). Biological invasion or bioinvasion. A broad term for both human-assisted introductions and natural range expansions (Carlton 2001).
Molecular biology is the study of the molecular underpinnings of the biological phenomena, focusing on molecular synthesis, modification, mechanisms and interactions. Biochemistry is the study of the chemical substances and vital processes occurring in living organisms. Biochemists focus heavily on the role, function, and structure of ...
Ectoplasm (cell biology) Ectoplasm (also exoplasm) is the non- granulated outer part of a cell 's cytoplasm, while endoplasm is its often granulated inner layer. It is clear, and protects as well as transports things within the cell. [1] Moreover, large numbers of actin filaments frequently occur in the ectoplasm, which form an elastic support ...
v. t. e. Standard anatomical terms of location are used to unambiguously describe the anatomy of animals, including humans. The terms, typically derived from Latin or Greek roots, describe something in its standard anatomical position. This position provides a definition of what is at the front ("anterior"), behind ("posterior") and so on.
Posthumanism or post-humanism (meaning "after humanism " or "beyond humanism") is an idea in continental philosophy and critical theory responding to the presence of anthropocentrism in 21st-century thought. [1] Posthumanization comprises "those processes by which a society comes to include members other than 'natural' biological human beings ...
The isopleth crosses the scale for T at just under 4.65. A nomogram (from Greek nomos νόμος, "law" and grammē γραμμή, "line"), also called a nomograph, alignment chart, or abac, is a graphical calculating device, a two-dimensional diagram designed to allow the approximate graphical computation of a mathematical function.
e. In chemistry, pH ( / piːˈeɪtʃ / pee-AYCH ), also referred to as acidity or basicity, historically denotes " potential of hydrogen " (or "power of hydrogen"). [1] It is a logarithmic scale used to specify the acidity or basicity of aqueous solutions. Acidic solutions (solutions with higher concentrations of hydrogen ( H+) ions) are ...
