Cell structure

Here you are another video about cells, cell types, estructures, etc where you can study or review this part of a living being.

Cell biology animation

Here you are a website where you can study the cell, processes, molecules and more. Take a look and enjoy.   Click on the link below.

Living things - Characteristics

As you already know, living things share several features that make them living things instead of non-living.
These are:

• To be formed by one or more CELLS 
• To have the same chemical COMPOSITION (C H O N)
• To perform the three VITAL FUNCTIONS (English speaking countries call the seven life processes)

Let's have a review in the following videos.

First and Second Law of Thermodynamics

Here is song written and played by Flanders and Swamn a long time ago that explains pretty clear the laws of Thermodynamics.

You can find the  lyrics of the song here (just in order to better follow the song).

DNA

Deoxyribonucleic acid (DNA) is the molecule that contains the genetic instructions of all known living things.

Here I leave an animated movie and related topics about DNA in order to learn about it.

3D anatomical model

By this application you will study and review human anatomy. It is a 3D anatomical model showing different layers of the human body.

The man who bottled evolution

Evolution is a slow process that cannot be seen in real time. So evidences of evolution are always searched backward in time, using the fossil record, genetics or biochemistry of living things today, but it cannot be studied forward (we never know how species are going to change).

Plates with bacteria culture

In 1988, at the Michigan State University, an experiment started with bacteria. Richard Lenski and his research group began to grow 12 populations of Escherichia coli and by reproducing and caring them day and night they have completed over 58.000 generations(equivalent to 1 million years in humans).

The conclusion in this experiment, which has been operating for over 25 years, is evolution never stops, even when the conditions of life do not change.

Darwin on the evolution trail

This video summarizes Darwin's life, from his early youth as a collector of insects through the 5 years trip on the HMS Beagle until he published his book "On the origin of species by means of Natural Selection". We can see how he was shaping and maturing his shocking and revolutionary idea of evolution and the difficulties he encountered .... even in his own wife ("I don't like your ideas, Charles!")

Periodic Table Song

Here you are a funny video about the elements of the Periodic Table. Although the elements are listed in order of atomic number in stead of groups or periods I'm sure that it will be usefull to learn and review about this unit. I hope you enjoy it as much as me.

Osmosis

Take a look closely at this couple of videos.   They will explain and clarify some concepts related to osmosis and cell membrane.
