Cell biology (also cellular biology or cytology) is a branch of biology that studies the structure, function, and behavior of cells. [1] [2] All living organisms are made of cells.
To obtain a result valid for non-zero temperature, we note from eq. (23) that z S d F D F = J 0 /d F. So when eq. (21) is integrated at non-zero temperature, then – on making this substitution, and inserting the explicit form of the Fermi–Dirac distribution function – the ECD J can be written in the form:
The location of the star within a galaxy may also affect the likelihood of life forming. Stars in regions with a greater abundance of heavier elements that can form planets, in combination with a low rate of potentially habitat -damaging supernova events, are predicted to have a higher probability of hosting planets with complex life.

Phage therapy is the use of bacteriophages to treat bacterial infections. Bacteriophage treatment offers a possible alternative to conventional antibiotic treatments for bacterial infection. [55]
Both external and internal temperatures are taken into consideration. The autoignition temperature is the lowest temperature at which the substance will ignite without an additional heat or ignition source (at atmospheric pressure). This temperature is used for classification for industry and technology applications. [6]
The notion of acoustic microscopy dates back to 1936 when S. Ya. Sokolov proposed a device for producing magnified views of structure with 3-GHz sound waves. However, due to technological limitations at the time, no such instrument could be constructed, and it was not until 1959 that Dunn and Fry performed the first acoustic microscopy experiments, though not at very high frequencies.
Coccoid bacteria often occur in characteristic arrangements and these forms have specific names as well; [8] listed here are the basic forms as well as representative bacterial genera: [3]
Congenital iodine deficiency syndrome (CIDS) is a medical condition present at birth marked by impaired physical and mental development, due to insufficient thyroid hormone (hypothyroidism) often caused by insufficient dietary iodine during pregnancy.
