what is virus

History:
             The first time this virus is discovered in China(city Bohan).The prevention or precautions are if you follow you will be safe from this disease. Actually, this is not the disease this is a genetically modified virus. It first time this disease is found in animals and then converted into a human.
Types:
          There are two types of viruses. 
1)DNA virus.
2)RNA virus.


1)DNA virus:
Mean: 
          Those viruses which are propagating due to DNA.
                                 
Explanation:
                    Ase we can know that DNA is the property of polymerase(enzymes). Which is the ability to repair the DNA sequence, as it is made the first stand and then come at the second time correct the sequence of the DNA. 
due o this property te DNA viruses change are not propagate that much, and it is finished after some time or it is converted to a genetic disorder.

2)RNA virus:
Mean:
          Those viruses which are propagating through RNA.

Explanation:
                    Ase we can know that RNA has no polymerase to re-correct the RNA sequence. That,s why RNA is spread throughout the world. Because of stopping this virus we can not make any antidote. Because if we give to that person who has already affected this virus you cannot give it to him.
Already his immunity was struggling and if you give to him his immunity system worked very fast and may be very dangerous for that person and he will die.
That is the reason for this that coronavirus is not stopping and spread out in the many countries of the world.

Can Not Take Medication:
                                          you are not taking any medication in the case of the virus effect. Because if you take medications your immunity will destroy the cell,s of your body. And if it is destroying your cell,s after some time you are all so dead.

Digestive System

Definition:                   "The mechanical and chemical break down of large, complex, non-diffusible food into small, simple, diffusible and soluble form is known as Digestion". 1)Mechanical digestion:                                       "The break down of food without the help of any chemical or enzyme action is called mechanical digestion". 2)chemical Digestion:                                    "The break down of food with the help of digestive juices or enzyme present in the digestive tract".                           Digestiv e System:                               "it is the system in which the organs are involved in the process of the digestive system or absorption. Part,s:           There are two different parts,s of the digestive tract. 1)Alimentary Tract:                                The food passes from that tract. It starts from the mouth and ends at the anus. It is consists of a mouth, pharynx, esophagu

Three type of chromosome

There are three main types of chromosomes on the base of ribosomes: 1:free chromosome 2:membrane bounded chromosome 3:orgnelleies bounded membrane No1:          Free chromosome they  are present insole or matrix of the cell.  Many are present in the mitochondria of the cell.                                    No2:        Membrane-bounded chromosome.  The single chromosome  of a prokaryotic cell is not enclosed  within a nuclear membrane . Among eukaryotes, the chromosome  is contained in a membrane boundary of the  cell nucleus .  No3:        O rganelles bounded chromosomes are mainly found in the cytoplasm of the cell.  In the animals, cells have different organelles such as the endoplasmic reticulum, Golgi apparatus, chloroplasts, mitochondria, and others. Have contained  several, rod-shaped chromosome.
