The progression of a cell by the cycle of cell is regulated by the protein family Cyclic
Explanation:
- In the year 1982, Cyclin was located by Timothy Hunt as a family of proteins which has a vital function in the progression of a cell.
- CDK enzymes or ‘cyclin dependent kinase’ gets activated by it that synthesizes the cycle of the cell.
- The concentration of this protein moves in a cyclic way in the cell cycle. No enzymatic function is seen in them but it aims at CDK’s different location.
Answer:
B) replaces injured tissues with connective tissue.
Explanation:
Inflammatory response:
When there is injury to the tissues by bacteria, toxins, heat, trauma or by any means then inflammatory response occurs by release of chemicals known as histamine, prostaglandins, bradykinin. It will prevent the spread of injurious agent to nearby tissue. It causes the swelling of tissue by liquid from the vessels. It also disposes of the pathogen and cellular debries and help in the repair of damage tissues.
