A flood can wash away important abiotic factors such as soil and rocks that certain biotic factors need for survival.
Degger [83]

Flooding is the term used to characterize the process that occurs when the waters of a river overflow due to rain and occupy the area next to the river, called the river plain. It can have natural or anthropogenic causes and affect vulnerable populations more often.

<h3>What is Biotic and Abiotic?</h3>

The biotic components are all the living things that live in a certain place, while the abiotic components are all the physical, chemical and geological factors of the environment such as water, light, soil, humidity, temperature, nutrients etc.

With this information, we can conclude that A flood can wash away important abiotic factors, such as soil and rocks, that certain biotic factors need to survive, thus flooding affects the ecology of affected regions.

Human Tissue-Resident Memory T Cells Are Defined by Core Transcriptional and Functional Signatures in Lymphoid and Mucosal Sites
beks73 [17]

Tissue-Resident Memory (TRM) can be found in both CD4+ and CD8+ T cell lineages and in a variety of tissue locations.

What are resident memory T cells?

  • Resident memory T cells are long-lasting, non-recirculating memory T cells found in epithelial barrier tissues such the gastrointestinal tract, lungs, skin, and reproductive tract.
  • In line with a recent study that found memory T cells specific for persistent viruses in human tonsils, the predominance of TRM-phenotype cells in all human lymphoid tissues include the spleen, lymph nodes, and tonsils, and reflect their long-term persistence over decades and/or continual pathogen exposure.
  • The cumulative encounter of different antigens over the course of a human lifetime may be the cause of TRM persistence in various places. The study of various diseases, from infection to cancer to inflammation and autoimmune disease, is becoming increasingly popular as a result of TRM.
