Symbiotic Relationships | NDK science

What is Symbiotic Relationships?

Symbiosis is any type of a close and long-term biological interaction between two different biological organisms, be it mutualistic, commensalistic, or parasitic. The organisms, each termed a symbiont, must be of different species. 

In normal words

Different species often inhabit the same spaces and share—or compete for—the same resources, they interact in a variety of ways, known collectively as symbiosis. There are five main symbiotic relationships: mutualism, commensalism, predation, parasitism, and competition.     

 

Human Symbiotic Relationships. 


When two species benefit from each other, the symbiosis is called mutualism (or syntropy, or crossfeeding). For example, humans have a mutualistic relationship with the bacterium Bacteroids the taiotetraiotamicron, which lives in the intestinal tract. 


An interesting example. 

The symbiotic relationship between an anemone (Heteractis magnifica) and a clownfish (Amphiron ocellaris) is a classic example of two organisms benefiting the other; the anemone provides the clownfish with protection and shelter, while the clownfish provides the anemone nutrients in the form of waste while also scaring

NDK Astronomy | Mars landing by NASA.

NDK Astronomy                   The mars landing by NASA. Resently 18/2/2021 National aeronutics and space adminstration launched a space rover for the red planet, Mars.  A Mars landing is a landing of a spacecraft on the surface of Mars. Of multiple attempted Mars landings by robotic, unmanned spacecraft, ten have had successful soft landings. There have also been studies for a possible human mission to Mars, including a landing, but none have been attempted.  The most recent landing took place on the 18 of February 2021 by the NASA rover  of 2021, all methods of landing on Mars have used an   aeroshell   and   parachute   sequence for   Mars atmospheric entry   and descent, but after the parachute is detached, there are three options. A stationary lander can drop from the parachute back shell and ride   retrorockets   all the way down, but a   rover   cannot be burdened with r...

Apple silicon chips | The M family.

Computers are made just like the human body. In the human body, the brain controls everything, handles every type of pressure occurring, and process the inputs and output it. Exactly like that the processor in computer plays or played a huge roll from the beginning of computers. Without a processor, the computer is like a human without a brain.  Nowadays there are various types of processors, as well as various large scale companies manufacture those. Simply the process of the processor is to handle the input - process them - Output it. So some examples for such companies are Intel, Nvidia, Apple and AMD.  When we take the most popular chip set Intel, For instance Intel has been founded in 1968 and been serving Windows and Apple devices since. Intel has 3 technologies named Intel single core, duo core and Quad-core.  But today's topic is not Intel, it is Apple M chips.  So when we take the history of Apple, from the beginning they manufactured Laptops and Computers n...
