Living plants may be valuable additions to science classrooms. Which is the most important safety consideration when planning to grow plants in a classroom? the light required for the plants to grow best
the nutrients to feed the plants
the composition of the soil in which to grow the plants
the structure and chemical properties of the plants

small, big, or no change could occur in the phenotype. it could cause something as simple as a cats ears to curl backwards or something as frighting as death. it could also occur in the protien-coding area and have an effect on that but no effect on the amino acids. what has to occur is a changing in the hox gene or the control gene.
