A food web is the natural interconnection of food chains and a graphical representation of what-eats-what in an ecological community. Ecologists can broadly define all life forms as either autotrophs or heterotrophs, based on their trophic levels, the position that they occupy in the food web.
Bioenergetics is a field in biochemistry and cell biology that concerns energy flow through living systems. [1] This is an active area of biological research that includes the study of the transformation of energy in living organisms and the study of thousands of different cellular processes such as cellular respiration and the many other metabolic and enzymatic processes that lead to ...
Biodegradation is the naturally-occurring breakdown of materials by microorganisms such as bacteria and fungi or other biological activity. [ 35] Composting is a human-driven process in which biodegradation occurs under a specific set of circumstances. [ 36] The predominant difference between the two is that one process is naturally-occurring ...
Photosynthesis ( / ˌfoʊtəˈsɪnθəsɪs / FOH-tə-SINTH-ə-sis) [ 1] is a system of biological processes by which photosynthetic organisms, such as most plants, algae, and cyanobacteria, convert light energy, typically from sunlight, into the chemical energy necessary to fuel their metabolism.
Phage display is a laboratory technique for the study of protein–protein, protein – peptide, and protein– DNA interactions that uses bacteriophages ( viruses that infect bacteria) to connect proteins with the genetic information that encodes them. [ 1] In this technique, a gene encoding a protein of interest is inserted into a phage coat ...
Biomimetics or biomimicry is the emulation of the models, systems, and elements of nature for the purpose of solving complex human problems. [ 2][ 3][ 4] The terms "biomimetics" and "biomimicry" are derived from Ancient Greek: βίος ( bios ), life, and μίμησις ( mīmēsis ), imitation, from μιμεῖσθαι ( mīmeisthai ), to ...
The investigating scientist (V. O. Kalinenko) referred to them as "bio-like structures" and "artificial cells". Formed in distilled water (as well as on agar gel) under the influence of an electric field, they lack protein, amino acids, purine or pyrimidine bases, and certain enzyme activities.
PowerPoint for the web is a free lightweight version of Microsoft PowerPoint available as part of Office on the web, which also includes web versions of Microsoft Excel and Microsoft Word. PowerPoint for the web does not support inserting or editing charts, equations, or audio or video stored on your PC, but they are all displayed in the ...
