Answer and Explanation:
The cell division cycle is responsible for increasing and maintaining cell number and size. This cycle is an essential feature of living organisms. There are four phases of cell division mitotic phase (M phase), growth phase 1 (G1), growth phase 2 (G2), and synthesis phase (S). One phase of the cell cycle ends, and the other starts; this is named a phase transition—a unidirectional alteration in the cell cycle phases. During G1, G2, and S phase cell grows and during the M phase cell divides. There are two models of cell reproduction as the clock model and the domino model. The domino model implies that cell division phases must occur in a distinct order and at a definite time. The domino model recommends that the cell cycle events are independent, while the clock model shows that the effectiveness of mitosis entrance was not persuaded by other actions.
Answer:
B. Replaces injured tissues with connective tissue
Explanation:
Inflammatory responses are natural defense mechanism of body of higher organisms which have been evolved to protect the organism from various types of infections and injuries. The main function of his response is to -
- Localize the injury so that it will not spread to the other parts of the body
- Eliminate the injurious agents to prevent further increase in the infection inside the body
- Remove the damaged tissue of the body so that it can start the mechanism of tissue healing
Thus, all the functions of the inflammatory responses that are mentioned in the options are correct except option B.
