Answer:
A good hypothesis needs to have clear concepts which must be testable by experimental or observational procedures
Explanation:
A scientific hypothesis is a possible explanation for a given phenomenon observed in the natural world. In the scientific method, a hypothesis is first raised, subsequently tested, and finally confirmed (or rejected) by empirical evidence. A scientific hypothesis needs to fulfill a series of characteristics: to be capable of being tested, to be understandable, to be precise, to be plausible, to define associations among experimental variables, etc.
Answer:
Explanation:
It is important that a cell undergoes replication before cell division occurs because, the main goal of cell division is to make more cells. And for all these cells to remain functional, all their components must be intact and complete. without this, these cells might not function. Thus, the goal of replication is to produce the next new copy that would go into one of the daughter cells produced. With DNA replication, the set of DNA present in a cell can be duplicated and then each daughter cell that results from division can have its own entire set of DNA and then cell division can theoretically continue as normal indefinitely.
