"maintaining a steady state internal environment, despite a changing external environment, is called homeostasis"
<span>Homeostasis is any self-regulating process by which biological systems tend to maintain internal stability with the tendency to resist external changes. Homeostasis involves negative and positive feedback loops.</span> <span>Homeostasis depends on the ability of the body to detect (via sensors) and oppose these changes. From sensors signals are sent to the control center<span> in the brain, and then after processing the information the </span>effectors are activated.</span>
Codominance - <span>A form of dominance in which the alleles of a gene pair in a heterozygote are fully expressed thereby resulting in offspring with a phenotype that is neither dominant nor recessive.
</span>Mutation<span> occurs when a DNA gene is damaged or changed in such a way as to alter the genetic message carried by that gene.</span>
