The productivity of autotrophs, such as plants, is called primary productivity, while the productivity of heterotrophs, such as animals, is called secondary productivity. [ 1 ] The productivity of an ecosystem is influenced by a wide range of factors, including nutrient availability, temperature, and water availability.
In the book's introduction, Bauer raises several questions which are examined in subsequent chapters. These questions are about the distinction between "productivity" and "creativity" (commonly understood as word-formation via, respectively, unconscious or semiconscious application of rules, and deliberate coining), the possibility of developing measures for productivity, the relationship ...
Neuroplasticity is the process by which neurons adapt to a disturbance over time, and most often occurs in response to repeated exposure to stimuli. [27] Aerobic exercise increases the production of neurotrophic factors [note 1] (e.g., BDNF, IGF-1, VEGF) which mediate improvements in cognitive functions and various forms of memory by promoting blood vessel formation in the brain, adult ...
Gross primary productivity is the amount of energy the producer actually gets. [13] [14] Generally, 60% of the energy that enters the producer goes to the producer’s own respiration. [12] The net primary productivity is the amount that the plant retains after the amount that it used for cellular respiration is subtracted. [13]
Productivity is the efficiency of production of goods or services expressed by some measure. Measurements of productivity are often expressed as a ratio of an aggregate output to a single input or an aggregate input used in a production process, i.e. output per unit of input, typically over a specific period of time.

A person simultaneously making use of a laptop and mobile phone. Human multitasking is the concept that one can split their attention on more than one task or activity at the same time, such as speaking on the phone while driving a car.
The units GDU and MCU are based on how fast one gram of the enzyme will digest gelatin or milk proteins, respectively. 1 GDU approximately equals 1.5 MCU. [ 2 ] An increased amount of substrate will increase the rate of reaction with enzymes, however once past a certain point, the rate of reaction will level out because the amount of active ...
Sequencing technologies vary in the length of reads produced. Reads of length 20-40 base pairs (bp) are referred to as ultra-short. [2] Typical sequencers produce read lengths in the range of 100-500 bp. [3] However, Pacific Biosciences platforms produce read lengths of approximately 1500 bp. [4] Read length is a factor which can affect the results of biological studies. [5]
