Saprotrophic nutrition / s æ p r ə ˈ t r ɒ f ɪ k,-p r oʊ-/ [1] or lysotrophic nutrition [2] [3] is a process of chemoheterotrophic extracellular digestion involved in the processing of decayed (dead or waste) organic matter.
All saprotrophic bacteria are unicellular prokaryotes, and reproduce asexually through binary fission. [2] Variation in the turnover times (the rate at which a nutrient is depleted and replaced in a particular nutrient pool) of the bacteria may be due in part to variation in environmental factors including temperature, soil moisture, soil pH, substrate type and concentration, plant genotype ...
Saprophyte may refer to: . Saprotrophs; organisms, particularly fungi, which obtain nutrients directly from dead organic matter or wastes; Myco-heterotrophs; plants, fungi, or micro-organisms that live on dead or decomposing matter and parasitize fungi, rather than dead organic matter directly.
Brain cells make up the functional tissue of the brain. The rest of the brain tissue is the structural stroma that includes connective tissue such as the meninges , blood vessels , and ducts. The two main types of cells in the brain are neurons , also known as nerve cells, and glial cells , also known as neuroglia. [ 1 ]
The human brain is the central organ of the nervous system, and with the spinal cord, comprises the central nervous system. It consists of the cerebrum, the brainstem and the cerebellum. The brain controls most of the activities of the body, processing, integrating, and coordinating the information it receives from the sensory nervous system ...
Lee's death was officially ruled the result of cerebral edema — swelling of the brain. While a normal human brain is about 3 pounds, Lee's was reportedly closer to 3½ pounds.
Despite the reduced brain matter, the man lived a relatively normal life; he was a married civil servant with two kids. He also scored an IQ of 75 which is considered low but not disabled.
A functional magnetic resonance imaging (fMRI) scan looks at oxygenated blood levels in the brain as a way of observing the activity of specific cortical areas. fMRI scans show dampened activity when anesthetized versus awake in rats, specifically claustrum connections to the medial prefrontal cortex (mPFC) and the mediodorsal thalamus (MD ...
