The cell theory consists of the rule that all living things must contain cells. The stuffed animal (since it is nonliving) has no cells. More evidence to prove this is that the stuffed animal comes from a manufacturer not other cells.
Explanation:
crossing over is a process that happens between human organs chromosome in order to increase general diversity. during crossing over part of one chromosome is exchange with another. the result is a hybrid chromosome with a unique pattern of genetic material. gametes gain the ability to be genetically different from their neighbouring gametes after crossing over occurs. this a loss for genetic diversity which will help cell participate in survival of the fittest and the evolution.
Science can answer many questions for example the speed of light, the frequency of pitch or sound, dna tests
