What is equilibrium

Please answer
And if help needed I am here to help anyone ☺️

if a body ,under the  action of  a number of forces ,is at rest or moving with uniform velocity ,it is said to be in equilibrium.or simply if a body is moving with uniform velocity it is said to be in equilibrium.

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.
