Chemistry 101: At Home Awesome Chemistry Experiments

Chemical reactions happen around us all the time. These reactions occur when we cook or bake and even in our bodies, like when we breathe. Everyday objects are able to react and cause incredible reactions. Here are some easy science experiments you can create using things you can find around the house. Make sure you act safely during the experiment and have fun!

Biology Unit 5 Study Guide: Evolution

Biology Unit 5 Study Guide: Evolution. After his visit to the Galapagos Islands, Darwin came up with the theory of evolution.  This theory stated that organisms change over time.  The way that organisms change is through the process of natural selection. With examples, practice questions, and answers to help make evolution respiration easy to learn!

Biology 101: Microfilaments vs Microtubules in Cell Biology

Microfilaments and microtubules are both important elements of the cytoskeleton, maintaining the structure and integrity of the cell, but there are several differences between microfilaments and microtubules. In this article, we share this information on microfilaments versus microtubules.

Microfilament and Microtubulues are made from different individual subunits. Microfilaments are made from ACTIN, while microtubules are made from TUBULIN.

An Introduction to Skeletal Muscles: Properties and Physiology

The muscular system allows us to move and do our daily tasks. It also provides heat, stability, and blood flow for our body. There are three main types of muscular tissue: cardiac muscle, which comprises the heart muscle, smooth muscle, which comprises the linings of organs, and skeletal muscle, which are the muscles that help our body move. This article will focus on the physiology of skeletal muscles.
