In biology, evolution is a process by which species change over time. Evolution is a theory-an explanation about how the world works, backed by evidence. The theory of evolution states that groups of organisms change over time. 1 That's because some individuals in the group survive to ...
catabolism,destructive metabolism,katabolism,dissimilation- breakdown in living organisms of more complex substances into simpler ones together with release of energy cell division,cellular division- the process in reproduction and growth by which a cell divides to form daughter cells ...
When it comes to adaptation, it is important to understand that climate change is a process. 2017年高考英语江苏卷 阅读理解 阅读D 原文 When these organisms die, they bury carbon in the deep ocean, an important process that helps to regulate t...
reproduces usually has a very high reproductive capacity, as so few of their offspring are likely to survive in aquatic environments. The number of organisms in a species, or any other defined population, that die over a certain period of time is referred to as this species’s mortality ...
With technological advances at single-cell resolution, researchers found that brain microglia are composed of heterogeneous populations among organisms with different lifespans, sexes and species6,7,8,9. It also boosted the identification of microglial markers, regulatory factors, pathways and gene ...
Figure 4. Nitrogen isotopic fractionation factors associated with the formation of organic nitrogen by aquatic organisms (i.e., algae, cyanobacteria, and bacteria) experimentally determined based on laboratory culture experiments and field observations. Fractionation factors (α) are expressed as ratio of...
For billions of years, all of the Earth’s organisms were gene machines, until, about 2 million years ago, just one species — our ancestors — started imitating sounds, gestures and ways of processing food. They had let loose a second replicator and turned us into meme machines. Following...
and produce more organisms. In this process,organic carbonis metabolized to produce heat, resulting in the temperature rise of compost materials (up to 70°C) to kill bacteria,insect eggs, and weed seeds. Theorganic nitrogen, however, is decomposed into inorganic ammonium ions and free ammonia ...
The life and operation of cells involve many physiological processes that take place over fast timescales of milliseconds to minutes. Genetically encoded technologies for driving or suppressing specific fast physiological processes in intact cells, perhaps embedded within intact tissues in living organisms,...
