Answer:
Instable behavior.
Explanation:
The checkpoints currently behaving instable in sally cancer cells because mutants show genetic instability so this instability is the cause of cancer disease. Two checkpoints are sensitive to DNA damage, one occur before mitosis cell division and the other occur before replication of DNA. So damage occur in these two check points leads to instable behavior of cancer cells.
<span>Plant and animal cells have different structures. One structural difference of plant cells and animal cells is the presence of the plant cell’s </span>cell wall,<span> specialized plastids and a large central vacuole which are not found within animal cells.
Another difference is the garbage disposal of each cell. Centrosomes and lysosomes are found in animal cells but both do not exist within plant cells. The animal cell’s garbage disposal takes place in the lysosome while garbage disposal of plant cells takes place in the vacuole.</span>
Answer: Traditionally, hornworts have been classified as bryophytes, together with mosses (division Bryophyta) and liverworts (division Marchantiophyta). In some classification systems, hornworts have been grouped as horned liverworts in the subclass Anthocerotidae (class Hepaticae), class Anthocerotopsida, order Anthocerotales.
