Biology: Lesson 130

There are many different levels of intelligence across various living organisms. Humans, no doubt, are the smartest of all life on earth, but it is still interesting to study some of the more intelligent animals. Besides humans, there are a few living organisms who have shown relatively high intelligence levels. Primates and elephants are thought …

Biology: Lesson 120

Many of the most successful pieces of technology we have today came from mimicking animals. There is still so much more we could achieve by researching animals, specifically those in the clade of Arthropoda, known as arthropods. Members in the clade of Arthropoda can be further divided into groups you may know: insects, crustaceans, arachnids, …

Producing fruit is a big investment for plants. However, it has proven to be a very effective method for distributing seeds. Often times, animals such as bears will eat the fruit, digest away the outer protective layer of the seed. When it leaves the bear in the form of feces, it will be in ideal …

Biology: Lesson 80

Plants have tiny openings called stomata. They will open or close them depending on the environment. If it's too hot, they will close their stomata to conserve water. But normally, they're open so the plant can access CO2 (carbon dioxide) from the air. Plants need CO2 for photosynthesis, but they also need light. In the …

Biology Lesson 40: Viruses

Viruses are very strange things. They are not considered to be alive, and yet they continue to survive by replicating in organisms, causing serious harm in the process. Nowadays there seems to be a lot of confusion in fighting viruses and bacteria. The two are very different, but most doctors typically treat them the same …

Biology Lesson 10: If Ice Didn’t Float

H2O. For it's simple composition, water is by far the most complex and useful substance out there. Our oceans contain vast amounts of it; so much that over 70% of the earth's surface is water. But to understand it's all of its amazing properties, it is crucial to first understand how it behaves on a …
