Social norms and deviance as covered in the MCAT is a fascinating topic, and in this episode, we'll break down the intersection of social norms—folkways, mores, taboos, and laws—how they play a crucial role in shaping societal values, and what happens when these norms break down, a concept known as anomy. Plus, we'll delve into collective behavior phenomena such as fads, mass hysteria, moral panic, and riots, touching on some real-life examples and historical comparisons.

Expect a comprehensive overview, with real-world relevance and plenty of examples to help solidify your understanding.

In this episode, we discuss population genetics and see how genetically related individuals share the same alleles, delving into the mechanisms of gene flow and genetic drift. We'll also unravel the complexities of hybrid vigor, reproductive isolation, and natural selection, and how these processes shape the genetic landscape of populations.

We'll also touch on the fascinating dynamics of X-linked and mitochondrial inheritance, and the role of genomic imprinting in disease risk. Ever wondered how the Hardy-Weinberg equation helps us understand genetic equilibrium in populations? We've got that covered too, breaking down the assumptions and applications of this essential model. Plus, we'll delve into how allele frequencies can shift due to factors like mutations and population bottlenecks.

In this episode, we'll explore three crucial hormone axes: the hypothalamic-pituitary-adrenal (HPA) axis, the hypothalamic-pituitary-gonadal (HPG) axis, and the renin-angiotensin-aldosterone (RAAS) system. We'll decode the complex interplays among the hypothalamus, pituitary gland, and various peripheral organs, focusing on how these hormone systems regulate everything from stress responses and reproductive functions to blood pressure and fluid balance.

We'll break down the HPA axis and its pivotal role in stress response, featuring hormones like corticotropin-releasing hormone (CRH) and cortisol. Next, we’ll navigate through the HPG axis to understand the hormonal orchestration behind testosterone, estrogen, and progesterone production. Lastly, we’ll zero in on the RAAS system, demystifying its essential function in blood pressure regulation and electrolyte balance.
