Alkanes are the most basic organic compounds. They are saturated hydrocarbons, which is just a fancy way of saying that they only contain single bonds and they are composed of hydrogens and carbons. Alkanes have a general chemical formula of CnH2n+2, where n equals the number of carbons. They are primarily used in gasoline, lubricatingContinue reading “Alkanes”

What is Matter?

Nothing. What’s the matter with you? Matter is defined as anything that has mass and takes up space. Mass is the quantity of matter an object contains and is measured in grams (g) and kilograms (kg). Mass is not to be confused with weigh, which is the force exerted on an object by gravitational attraction.Continue reading “What is Matter?”

Prokaryotic vs Eukaryotic Cells

Bacteria cells are prokaryotic, and all other cells are eukaryotic. the biggest difference between them is that eukaryotic cells have a membrane-bound nucleus and membrane-bound organelles, whereas prokaryotic cells have neither a membrane-bound nucleus nor membrane-bound organelles. Prokaryotic cells (0.1-10 micrometres) are generally smaller than eukaryotic cells (10-100 micrometres). There are many benefits to havingContinue reading “Prokaryotic vs Eukaryotic Cells”

Characteristics of Life II

So far we have covered five characteristics of life: organization, nutrition, excretion, response and reproduction. However, these characteristics do not go far enough into explaining what life actually is. The levels of biological organization do not stop at the cell or population. We can go smaller than the cell in terms of organelles, molecules, andContinue reading “Characteristics of Life II”
