The two distinct physiological phenomena to be suggested, which could be responsible for the observed difference in the corticosterone response to a stressor in nonhabituated and habituated penguins. Introduction: Corticosterone is a steroid hormone belonging to the category of glucocorticoids, which are produced in the adrenal cortex of vertebrates. CRH (corticotrophin-releasing hormone) is a hormone released by the hypothalamus in stress conditions. The secretion of this hormone eventually leads to the secretion of corticosterone hormone. In habituated penguins, hormone secretion of CRH will be less, which would contribute to lesser secretion of corticosterone.

Humans consider themselves amazingly clever and innovative, constantly developing "new" ways of altering the world around us. As material consumption has increased, many have turned to the ideas of recycling and reuse as a means to minimize some negative aspects of our modern consumerism. Mother Nature though is the ultimate innovator and, more importantly, the ultimate recycler.

Alleles at the P locus control seed color. Plants which are pp have white seeds, white flowers and no pigment in vegetative parts. Plants which are P_ have black seeds, purple flowers and may have varying degrees of pigment on stems and leaves. Seed color can be assessed, visually, based on if the seed is white or not white A gene for mold resistance has been reported and we want to determine its inheritance and whether it is linked to P. For the purposes of this exercise, we will assume that resistance is controlled by a single locus M, and M_ plants are resistant and mm plants are susceptible. Resistance can be measured, under greenhouse conditions, 2 weeks after planting, by injecting each seedling with a spore suspension. After two weeks, the seedlings can be rated as resistant or susceptible, based on whether or not tissue is actively sporulating. For this exercise we will use seed and data from the F10 generation of a recombinant inbred population produced using single seed…
