Overview: Biology 2e is designed to cover the scope and sequence requirements of a typical two-semester biology course for science majors. The text provides comprehensive coverage of foundational research and core biology concepts through an evolutionary lens. Biology includes rich features that engage students in scientific inquiry, highlight careers in the biological sciences, and offer every…
In this video we are going to look at what density is, how it is measured and the differences in density between the different states of matter. Informally, density is a measure of how ‘packed’ a material is with mass. Density is defined as the mass of an object per its unit volume. So the big beach ball has a small mass but a big volume, meaning it’s density is low. Whereas the pebble is…
his textbook is an introduction to the ideas and techniques of linear algebra for first- or second-year students with a working knowledge of high school algebra. The contents have enough flexibility to present a traditional introduction to the subject, or to allow for a more applied course. Chapters 1–4 contain a onesemester course for beginners whereas Chapters 5–9 contain a second semes…
There are some key angles that have exact values in trigonometry. The ones we need to know are 0, 30, 45, 60 and 90. In this video we will discover one method of remember what these values are - by counting fingers on our hand! In the first part we discovered a different method (constructing a table) which you may prefer. Choose whichever method works best for you. SUBSCRIBE to the Fus…
Summary – the theory of plate tectonics had enabled us to explain the origin of earthquakes, volcanoes, mountain building and has told us the fascinating history of the earth. To find out the evidence for all this watch “Wegener and the proof of continental drift.” Tags: digital learning, online learning, learn chemistry, school chemistry, chemistry, gcse chemistry, high school chemistry…

DNA (deoxyribose nucleic acid) is extremely important. All living things have DNA, or in the case of some viruses they have RNA instead. In eukaryotes, it is found within the nucleus and is arranged into chromosomes. DNA determines the characteristics of an organism. Specific codes of DNA are called genes. DNA is made up of nucleotides. Nucleotides are repeating units, that are made up…
Hydrogen is a gas at room temperature, and is the first element in the periodic table. It has the chemical symbol H, but is usually found as a diatomic molecule of H2.

Rabies is an acute, progressive, incurable viral encephalitis found throughout the world. Despite being one of the oldest recognized pathogens, its impact remains substantial in public health, veterinary medicine, and conservation biology. Thus, it is Essential to apply existing tools and to seek new methods to improve upon prevention, control, selective variant elimination, and treatment effor…
