A neuron consists of three main parts: the cell body, or soma; dendrites, which are branch-like extensions of the cytoplasm that receive input from other neurons; and an axon (usually just one), which transmits input to the end of the neuron, where substances called neurotransmitters are re...
It is often unclear if cell types defined by different phenotypic features agree with each other nor which feature is the right one to define cell types. Furthermore, lacking a systematic approach and effort, we do not know if all the cell types in an organism have been identified and ...
phagocytosis is slightly different, according to Maciver. Giant amoebae engulf their prey "by the willful gathering of pseudopods around the bacteria." In both cases, as the bacteria is drawn in, the cell membrane that surrounds it pinches off to form an intra-cellular compartment called the ...
“If you think 20 percent of genetic information in your nose is a lot of biological dark matter, if we looked at your gut, up to 40 or 50 percent of that information is biological dark matter. And even in the relatively sterile blood, around one to two percent of this information is...
Yeastis a living single celled organism commonly used in baking. Yeast is a type of leavener ( baking soda and baking powder can also be used asleavening agents). Yeast converts sugar and starch ( from the sugar and flour in the bread mix ) into carbon dioxide and ethanol. The carbon ...
