The theory of evolution.

                                      The theory of evolution. 


Evolution is change in the heritable characteristics of biological populations over successive generations. These characteristics are the expressions of genes that are passed on from parent to offspring during reproduction. To this matter one will almost always become familiar with Charles Darwin, perhaps the greatest of all contributors. As a naturalist, Darwin was not only responsible for the theory of evolution as we know it today, but also the foundation that biological sciences are based on. Evolution is change in the heritable characteristics of biological populations over successive generations. These characteristics are the expressions of genes that are passed on from parent to offspring during reproduction. Modern humans originated in Africa within the past 200,000 years and evolved from their most likely recent common ancestor, Homo erectus, which means 'upright man' in Latin. Homo erectus is an extinct species of human that lived between 1.9 million and 135,000 years ago. As a fact we all believe different things so some of you may not believe the theory of evolution but some might. It is up to you to decide.

Theory of Hypnosis

 Hypnosis  Today we're going to discuss about something deep minded. Hypnosis is  a human condition involving focused attention, reduced peripheral awareness, and an enhanced capacity to respond to suggestion. There are competing theories explaining hypnosis and related phenomena. Its a  trance-like state in which  you have heightened focus and concentration . Hypnosis is usually done with the help of a therapist using verbal repetition and mental images.  Not everyone can be hypnotized , but two thirds of adults can, and people who are easily hypnotized tend to be more trusting of others, more intuitive and more likely to get so caught up in a good movie or play that they forget they're watching one, Spiegel explains.  How is hypnosis done? During hypnosis, a trained hypnotist or hypnotherapist induces a state of intense concentration or focused attention. This is a guided process with verbal cues and repetition. The trance-like state you enter m...

How are vaccines made? | mRNA technology explanation.

   Pfizer/ Moderna  As you know these vaccines are made of a new technology called mRNA technology.  therefore before we discuss about this, I am going to briefly explain how other vaccines such as sinopharm, astrasenica & suptnic V are made. They are made of the normal technology which is not new, If we say it in the normal words these vaccines are made of from an inactive covid virus. So when injected to your body your immunity system will be trained to defeat the active covid virus. This is the technology used in other vaccines other than pfizer and moderna vaccines. So when we talk about mRNA technology,  mRNA is created during the process of  transcription , where an  enzyme  ( RNA polymerase ) converts the gene into  primary transcript  mRNA (also known as  pre-mRNA ). This pre-mRNA usually still contains  introns , regions that will not go on to code for the final  amino acid sequence . These are removed in the ...
