Plants and animals respond to stimuli. discuss their similarities and differences.

Fundamental differences between plants and animals shape the ways they perceive their environments and respond (see also [75,76]). Plants, unlike animals, are less mobile (top), are constructed of repeated modular units (middle), and are more tolerant of attack and loss of some tissue (bottom).

Explanation:

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.
