A、An organism upon which an organism of a different species grows and from which all or most of its food is derived. B、an organism that causes disease. C、A saclike structure, usually containing eight ascospores or the sexual spores of the Ascomycota, formed by karyogamy and meiosis. ...
Parasiteis <br/> A、an organism that grows part or all of the time on or within another organism of a different species(known as its host),and from which it derives all or part of its food. <br/> B、an organism that lives on dead organic matter.<br/> C、
GMO is defined as “an organism (…), in which the genetic material has been altered in a way that does not occur naturally by mating and/or natural recombination.” From: Genomics and the Global Bioeconomy, 2023 About this pageSet alert ...
If we look at this problem more closely, the term “anaerobes” covers a wide range of biological variations including permanent or time-dependent tolerance to O2[2]. Here, “tolerance” means that growth and development is restricted by O2, but ananaerobic organismcan still be alive, and is...
Small chemical compounds that enter an organism unnaturally, such as drugs or pollutants. Acidic dissociation constant (pKa). The equilibrium constant for the dissociation of an acid into its conjugate base and hydrogen ion, expressed as the negative logarithm. The lower the pKa of a sulphydryl ...
Stress, often caused by unpredictable and unpleasant events and circumstances, pervades modern life. Acutely, stress elicits adaptive physiological and behavioral responses through which the organism maintains physiological stability, a process termed “allostasis” [1]. However, prolonged stress may overwhel...
organism will be a result of such proteins. In other words, the specific sequences that are trasmitted in genes are a memory of characters that are adapted to the environment. Jacob’s Law suggests that even in the subsequent major levels–cognition and culture–some information is transmitted...
(cellular colonies which outlive the organism, such as hair and fingernails, remain uninfected). Once infected, the host’s dead cells undergo a radical transformation. The cells are effectively reanimated, although they are so altered that it would be inaccurate to describe the host organism as...
However disease is a more complex process that may result from direct virus effects, immune responses to infection, or a combination of both. Modern studies of viral pathogenesis seek to understand not only the damage to an organism but the underlying molecular events that cause the observed ...
So far, SARS is the most severe human disease caused by a coronavirus. Recent evidence confirmed that the SARS-CoV virus originated from a mutation occurring in a non-human host, probably bats, gains the ability to affect humans. Luckily, the transmission of SARS-CoV was relatively inefficient...
