The African pygmy phenotype stems from genetic foundations and is considered to be the product of a disturbance in the growth hormone–insulin-like growth factor (GH–IGF) axis. However, when and how the pygmy phenotype is acquired during growth remains
Growth in plants is of indeterminate type i.e plant grow through out their life because of presence of meristematic tissues present in specific p[arts of plant i.e apical intercalry and lateral These tissue has abiltiy to divide continuously and contribu
Different tissues and different regions of the body mature at different rates, and the growth and development of a child consists of a highly complex series of changes. It is like the weaving of a cloth whose pattern never repeats itself. The underlying threads, each coming off its reel at ...
following an increase in the population of zooplankton (minute aquatic animals), the population of their algae prey may decrease or grow at a slower rate. This results in anoscillatingpopulation pattern, such as the cyclical fluctuation of thesnowshoe hareand lynx populations, as depicted in Figure...
B. The appearance of a certain pattern of categories. C. The language used in the submitted summaries. D. The appearance of wildlife animals and plants.(姊妹题)14. Why did the researchers name each nature experience? A. To create a universal language for people to communicate. B. To find...
We develop a model for ontogenetic growth of animals, applicable to ad libitum and food limited conditions, based on an energy balance that expresses growth as the net result of assimilation and metabolic costs for maintenance, feeding and food processing. The most important contribution is the ...
Soil nutrient status of hill agro-ecosystems and recovery pattern after slash and burn agriculture (Jhum) in north-eastern India The present study deals with fertility changes in agro-ecosystems where vegetation is removed by slash and burn procedures, the land is planted to crops (c......
To the extent that descriptions of cultural values mention specific attributes, they seem to align well with the ecological attributes of large trees, old age, canopy layers, open understories, diverse plants and animals, and patchiness of large and small trees. Many of the values appear to dep...
To detect the relationship between bamboo growth status and woody plants in a giant panda habitat, we carried out a field survey in the Wanglang Nature Reserve, Sichuan Province, China. We used bamboo clump number and bamboo height to describe the growth status of bamboo. We found bamboo heig...
The release of vesicles from the outer membrane of Gram-negative bacteria. Blebbing occurs during normal growth and is enhanced in certain mutants that are impaired in cell division. Lysozyme An antibacterial enzyme that is produced in animals, plants, fungi and even bacteria and is capable of ly...
