Answer: The scientific method is cyclic.
Explanation: Scientific methods is the systematic way of using knowledge , hypothesis , observation , theories and experiments , to give us understanding for the questions.
Scientific method is always cyclic as it involves several steps. Cyclic way give us better understanding about facts and whole phenomena.
Answer:
Cyclic
Explanation:
Scientific method comprises of various complex procedures or cycle. Scientific method involves a lot of people and ideas usually generate more and new ideas. It doesn’t usually follow a set guideline or step.
It involves raising up of more questions as more ideas are discovered . It makes sure the analysis and procedure is a very thorough one with no issue.
An antigen is a biomolecule, such as a protein or sugar, that binds to a specific antibody. An antibody/antigen interaction may stimulate an immune response. Not every biomolecule is antigenic and not all antigens produce an immune response. B cells are the major cell type involved in the humoral immune response.
The key biomolecule involved in the immune system is a protein known as an antibody. These are produced by B cells and help the immune system recognize and destroy foreign substances like bacteria or viruses.
The biomolecule that has significant involvement in the immune system is a group of proteins known as antibodies or immunoglobulins. These antibodies are produced by certain types of white blood cells (B cells). They play a crucial role in the immune response by recognizing and binding to specific antigens such as bacteria or viruses, enabling other parts of the immune system to destroy these foreign substances more effectively. For example, if a person becomes infected with a virus, the immune system will produce antibodies specific to that virus. Once these antibodies attach to the virus, they basically mark it for destruction by other cells in the immune system.
