Organisms can reproduce. They can give rise to another of the same kind (species). There are essentially two ways to do this: (1) bysexual reproduction, i.e. involvinggametes, or (2) byasexual reproduction, i.e. a reproduction that does not involve gametes. In asexual reproduction, the...
Organisms are highly organized structures that consist of one or more cells. Even very simple, single-celled organisms are remarkably complex. Inside each cell, atoms make up molecules. These in turn make up cell components or organelles. Multicellular organisms, which may consist of millions of i...
21Eukarya真核域The domain that includes all eukaryotic organisms.包括所有真核生物的领域。 22natural selection自然选择A process in which individuals that have certain inherited traits tend to survive and reproduce at higher rates than other individuals because of those traits.具有某些遗传特征的个体往往比...
Large compendia of gene expression data have proven valuable for the discovery of novel biological relationships. Historically, most available RNA assays were run on microarray, while RNA-seq is now the platform of choice for many new experiments. The da
reproduce it, to reconstruct it from artificial components. This epistemological change is probably the result of the progressive acknowledgment that the plain description of the complex molecular networks present in organisms is not sufficient to account for their behaviour. This ‘new’ (for ...
Each compound is linked to a putative target, and the use of model organisms and virtual screening of structural models provides leads for target identification. Prioritized compounds are now poised for testing in animal models of infection as well as in vitro characterization against other filarial...
In fact, there are a lot of marine plants that survive, that grow and reproduce in surfacewaters. 事实上,有很多海洋植物生存下来了,在表层水里茁壮成长,不断繁殖。 In particular, there are a lot of diatoms. 那里特别多硅藻。 Diatoms are microscopic, photosynthetic organisms and they are a major...
Figure 10. All the organisms within a clade stem from a single point on the tree. A clade may contain multiple groups, as in the case of animals, fungi and plants, or a single group, as in the case of flagellates. Groups that diverge at a different branch point, or that do not in...
capturing the achieved sensory diversity of a species or clade. The sensory perception of the organisms themselves, and the capacity for contrast among those perceptions, are central to the intellectual goal of quantifying a color gamut. Because each of the edges of a convex hull is a potentially...
