Nitrification is one of the crucial steps of the nitrogen cycle that occurs in soil. It is an aerobic process that involves two successive oxidation reactions, where the ammonia first oxidizes into nitrites, and then nitrites get oxidized into nitrates. It occurs in the soil, which includes members of autotrophic bacteria and archaea that facilitate …
Difference between ATP and ADP is mainly due to the given three factors like their energy state, a number of phosphate groups and the hydrolysis process. Energy state: ATP is comparatively high energy molecule than ADP. Phosphate group: There are three phosphate group in ATP, while two in ADP. Hydrolysis: As a result of hydrolysis, …
Difference between unicellular and multicellular organisms is primarily due to the difference in cell composition, cell function and cell arrangement. Cell composition: The unicellular and multicellular organisms incorporate a single cell and multiple cells, respectively. Cell’s function: Unicellular organisms mediate all their cellular activities by a single cell itself, while multicellular organisms perform specific cell …

Difference between water-soluble and fat-soluble vitamins is primarily due to the difference in the process of absorption and excretion rates inside a body. Absorption: Water-soluble vitamins are readily absorbed in the small intestine, while fat-soluble vitamins are first absorbed in the lymph, later stored inside a liver and fatty tissues. Excretion: Water-soluble vitamins swiftly excrete …

Neurotransmitters also refer as “Chemical messengers” that is composed of molecules like amino acids, amines, purines and neuropeptides. Its activity can inhibit or excite the production of a nerve impulse. Its synthesis occurs endogenously by the presynaptic-neuron and releases out on membrane stimulation. Neurotransmitter ensures neurotransmission by transmitting an action potential beyond the chemical synapse. …
Synapse is a term that was first coined by Charles S. Sherrington in the year 1897 and derived from the Greek word “Synapsis” which means to conjugate or clasp. The communication between the neurons is through synapses only that helps in the transmission of a nerve signal from one to the next cell. A scientist …
Nerve impulse can define as the generation of action membrane potential beyond the cell membrane in response to the stimulus. The propagation of nerve impulse, as a result of a change in membrane potential beyond the cell membrane commonly, refers to as “Nerve impulse conduction”. When a nerve impulse or action potential reaches the axon …
Neurons are the fundamental components of the nervous system that perform a specific task by receiving, conducting, and transmitting the signal or action potential to the other parts of the body. An electrical signal produced by the neurons refers as Nerve impulse that propagates via continuous and saltatory conduction. A term neuron is sometimes interchangeable …
Sclerenchyma tissue can define as one of the types of ground or simple permanent tissue that constitutes both primary and stiff secondary wall. These are generally rigid woody cells with a compact arrangement. Sclerenchyma has a characteristic feature, where it functions to promote cell strength and conduction instead of being a dead cell. On secondary …
Mitotic division shows a pattern of cell division, where a single cell multiplies into two similar daughter cells by the segregation of newly replicated chromosomes in the nucleus. It is the intermediate phase of the cell division that activates after the G-2 interphase and ends with the stage of cytokinesis. Mitosis is a part of …
