Introduction to Animal Diversity – (Part One)

This is a introduction to Animal diversity! Animals are super diverse, and even though this is an introduction, it is going to be a long post. So grab a cup of tea, sit back, and enjoy the read! This is part one and there will be a second part posted later. The first animal fossils [...]

The Evolution of Populations

Welcome to our continuing AP Biology/ General Biology series here on STEM Talks! The purpose of this post is to talk about population evolution Each organism's traits affect its survival and reproductive success compared with those of other individuals. But the evolutionary impact of natural selection is only apparent in how a population of organisms [...]

The Tree of Life

Welcome to the next StemTalk! This is going to be about the tree of life. This talk is going to go over the history of Earth's formation in a very brief manner. Earth formed around 4.6 billion years ago, condensing from a large cloud of dust and space rock to form the first structure. Condensation [...]

Carbohydrates: the fuel and building material of organisms

Hey all! This blog post is a part of STEMTalksNC’s ever expanding General Biology Series. In the last post, we talked about how macromolecules were built. In this post, we will examine the structure and function of carbohydrates. Monosaccharides Carbohydrates include sugars and polymers of sugar. Monosaccharides, the simplest carbohydrates, generally have molecular formulas that [...]

Heredity- A Shallow Look

Living Organisms are distinguished by their ability to reproduce their own kind. Heredity is the transmission of traits from one generation to the next. Along with these these inherited traits, there is also variation- the offspring differ somewhat in appearance from parents and siblings. We will first establish that offspring acquire genes from parents by inheriting chromosomes.
