Texas Gateway: Internal Feedback Mechanisms

When nature calls, you need to answer. Physiology learners discover that it is a just your body's way of regulating pressure and water content. Along with osmoregulation, they also examine thermoregulation, two vital processes with which...

Explore homeostasis in animals with this all-encompassing learning exercise. Advanced biology pupils consider a variety of mechanisms for maintaining internal conditions such as temperature and waste products. Eighteen short-answer...

Study the process of by which humans respond to their environment to reach equilibrium in this tutorial. Learn that feedback mechanisms trigger living things to respond to their environment.

By the end of this section, you will be able to describe the definition, aims, and branches of physics; describe and distinguish classical physics from modern physics and describe the importance of relativity, quantum mechanics, and...

By the end of this section, you will be able to associate physical quantities with their International System of Units (SI) and perform conversions among SI units using scientific notation; relate measurement uncertainty to significant...

Gene pools can change as a result of genetic drift and other mechanisms. This tutorial will investigate how gene pools change and evolve.

Given illustrations or partial DNA sequences, students will identify changes in DNA and the significance of these changes.

Given diagrams, illustrations, or descriptions, students will identify the types of energy.

Given diagrams, illustrations or relevant data, students will identify examples of kinetic and potential energy and their transformations.

This tutorial investigates protein synthesis. Learn about the steps of transcription and translation that take place to form a protein.
