In this lab the rate of germination in relation to temperature was observed testing the hypothesis‚ if the seeds are exposed to cold temperatures then they will not germinate. In the standard germination test a total of one hundred corn seeds were divided into four groups of twenty-five and each group was used to make a ragdoll. The rag dolls were germinated in room temperature. In the cold test one hundred corn seeds were placed on four layers of moist paper towels in the bottom of a metal tray

The reproductive system is a collection of internal and external organs (male and female) that work together for the purpose of recreating. Many scientists argue that the reproductive system is the most important system in the body.

Many people argue if the embryo research is right or wrong and if it’s beneficial or just a waste of time. There are some good things about embryo research
