Some compounds contribute to antioxidant defense by chelating transition metals and preventing them from catalyzing the production of free radicals in the cell.

Some components of membranes play a key role in medicine, such as the efflux pumps that pump drugs out of a cell.

Some of these groups have been transferred out of the Kingdom Fungi, in part because of fundamental biochemical differences in the composition of the cell wall.

Some algae may store food in the form of oil droplets. Green algae usually have a rigid cell wall made up of an inner layer of cellulose and outer layer of pectose.

Some drugs cause cells to undergo apoptosis ( so-called " self-programmed cell death ").

Some bacteria, such as E. coli, have several flagella per cell ( 4 – 10 typically ).

Some models even have no turn-off button but they provide some way to put off, for example, leaving no operation for a moment, covering solar cell exposure, or closing their lid.

Some cytokines, such as Fas ligand, are used as " death " signals ; they cause target cells to undergo programmed cell death or apoptosis.

Some neurons do, however, communicate via electrical synapses through the use of gap junctions, which allow specific ions to pass directly from one cell to another.

Some sources use edge to refer to a ridge, while H. S. M. Coxeter uses cell to denote an ( n − 1 )- dimensional element.

Some proteins, such as insulin, are extracellular proteins that transmit a signal from the cell in which they were synthesized to other cells in distant tissues.

Some authors explain pixel as picture cell, as early as 1972.

* Some viruses, for example, the Semliki forest virus, enter the cell through this mechanism.

Some promoters are called constitutive as they are active in all circumstances in the cell, while others are regulated becoming active in response to specific stimuli.

Some provirus remains latent in the cell for a long period of time before it is activated by the change in cell environment.

Some TEs contain heat-shock like promoters and their rate of transposition increases if the cell is subjected to stress, thus increasing the mutation rate under these conditions, which might be beneficial to the cell.

# Some proteins involved in cell adhesion prevent tumor cells from dispersing, block loss of contact inhibition, and inhibit metastasis.

Some have hormone-like functions as regulators of mineral metabolism ( e. g., vitamin D ), or regulators of cell and tissue growth and differentiation ( e. g., some forms of vitamin A ).

* Some specialty Batteries ( e. g. lithium, nickel cadmium, or button cell batteries )

Some key developments in biology were the discovery of genetics ; Darwin's theory of evolution through natural selection ; the germ theory of disease and the application of the techniques of chemistry and physics at the level of the cell or organic molecule.

Some newer flash memory, known as multi-level cell ( MLC ) devices, including triple-level cell ( TLC ) devices, can store more than one bit per cell by choosing between multiple levels of electrical charge to apply to the floating gates of its cells.

Some of them are obvious, such as the fact that we associate recorded and live music with our responses and behavior in different types of environments and social settings.

Some popular designs use the following types of ANOVA:

Some types of motions will not be accepted by the court unless accompanied by an independent sworn statement or other evidence, in support of the need for the motion.

Some types of neurons have no axon and transmit signals from their dendrites.

Some recent types have a parallel pair of magnetically-soft probes that are placed on either side of the conductor.

Some of the oldest pre-system sewage types are pit toilets, latrines, and outhouses.

* Some types of hedge funds make use of a modified form of arbitrage to profit.

Some basic types of responsiveness such as reflexes can be mediated by the spinal cord or peripheral ganglia, but sophisticated purposeful control of behavior based on complex sensory input requires the information-integrating capabilities of a centralized brain.

Some types of worms, such as leeches, also have an enlarged ganglion at the back end of the nerve cord, known as a " tail brain ".

Some common types include:

Some bean types include:

Some examples are in improving crop technology ( not a medical application per se ; see BioSystems Engineering ), the manufacture of synthetic human insulin through the use of modified bacteria, the manufacture of erythropoietin in hamster ovary cells, and the production of new types of experimental mice such as the oncomouse ( cancer mouse ) for research.

Some types of instructions manipulate the program counter rather than directly produce result data.

Some classic examples of these types of tasks are multimedia applications ( images, video, and sound ), as well as many types of scientific and engineering tasks.

Some printer technologies don't work with certain types of physical media, such as carbon paper or transparencies.

Some printers can process all three types of data, others not.

Some philosophers believe that Block's two types of consciousness are not the end of the story.

Some types of banking regulation may be delegated to other levels of government, such as state or provincial governments.

Some types of self-starting synchronous motors always started when power was applied, but in detail, their behavior was chaotic and they were equally likely to start rotating in the wrong direction.

Some of the most widely used types of modern cannon are howitzers, mortars, guns, and autocannon, although a few superguns — extremely large, custom-designed cannon — have also been constructed.

Some types of chemotherapy are gonadotoxic and may cause infertility.

Some states, such as Virginia, do not provide for any class actions, while others, such as New York, limit the types of claims that may be brought as class actions.

Some types of smaller thermionic rectifiers sometimes had mercury vapor fill to reduce their forward voltage drop and to increase current rating over thermionic hard-vacuum devices.

Some of them are not main-stream types, but most of them have received special attention ( e. g., in research ) due to end-user requirements.
