When we look at a species, oftentimes we notice that they do not all look exactly the same. Perhaps the color of their fur differs or the length of their legs varies. This variation is natural and is essential for survival. In this episode, we explore how this variation can be preserved in order to maintain a healthy population. The six mechanisms we discuss are balanced polymorphism, sexual reproduction, outbreeding, diploidy, heterozygote advantage, and frequency dependant selection.

Cell cycle regulation helps our cells control when they want to divide and when they do not. In this episode, we dive into cyclins, cyclin-dependant kinases, mautration-promoting factors, platelet-derived growth factors, and p53. 

Mutations are essential to the survival of organisms. It drives evolution, creating diversity. But, it also has its consequences. In this episode, we explore the benefits of mutations but also their pitfalls. We discuss gene mutations, chromosomal mutations, insertions, deletions, point mutations, and diseases caused by mutations. 

With countless organisms roaming the Earth, it is important to have a system to classify them all. The 3-Domain Classification System is a way to sort organisms into 3 categories: bacteria, archaea, and eukarya. In this episode, we explore each of these classfications and the criteria each requires. 

Enzymes play a large role in enzymatic reactions so being able to control them is essential. In this podcast, we explore competitive inhibition, noncompetitive inhibition, and cofactors and how they affect enzymes. 

What are the differences between Eukaryotes and Prokaryotes? This episode begins by discussing the essential components that all cells need and then transitions into in-depth explanations on Prokaryotes and Eukaryotes. The episode closes with a comparison between the two cell types.

Community Ecology is the discussion of all of the interactions between organisms in a community. Today, we will be going into depth on the 5 categories of community ecology: competition, predation, herbivory, symbiosis, and facilitation. 

The world of science is advancing faster than ever, especially in biotechnology. With scientists pushing through the frontier, many innovations are being made and it is important to keep up. In today's episode, we will be discussing CRISPR, Polymerase Chain Reactions, Restriction Enzymes, Gel Electrophoresis, and DNA probes. Additionally, we will also be discussing the ethics involved in the biotech industry.

Water is essential to life on Earth. Without it, no life as we know it would exist today. Water has many essential properties that allow for it to sustain life on this Earth and this podcast goes into detail on the 5 major properties: high specific heat, high heat of vaporization, universal solvent, strong cohesion tension, and ice is less dense than water. We will also be discussing atomic structure and types of bonds in order to better understand the properties of water. 

This podcast reviews environmental impacts on enzymes topic 3.3. Enzymes are incredibly important as they are what allow our bodies to complete the required reactions and keep us alive! We will be discussing denaturation and the three major environmental impacts on enzymes which are temperature, pH, and concentration of substrates and inhibitors.
