A biology blog for students
Photosynthesis is one of the most heavily discussed topics in biology courses. Probably a reason why they are regarded as such an important topic is because they have impacted Earth's atmosphere in the course of centuries if not thousands of years. Today we will take a look at how photosynthesis altered Earth's atmosphere for millions... Continue Reading →
A couple of weeks ago, we discussed cell respiration - the controlled release of energy to produce ATP. In order for both anaerobic and aerobic cell respiration to take place, the exchange of hydrogen molecules, electrons, and oxygen reactions are crucial. Today we will learn redox reactions, which is a combined word for reduction and... Continue Reading →
The behavior of cells is similar to that of humans in that it needs energy to survive. Cells acquire energy, or ATP, through cellular respiration in the mitochondria. With this energy, cells allow us to move our muscles, repair damaged cells, digest food, and carry out many more critical processes. Today we will learn the... Continue Reading →
On the last post, we talked about the polarity and thermal properties of water. Today we will continue on the discussion of properties of water and move on to the cohesive, adhesive, and solvent properties. Cohesive Properties of Water The definition of cohesion is the "binding together of two molecules of the same type." Water... Continue Reading →
Water is often referred to as the medium of life. It is an essential component to all forms of life - 65% of human body cells are made up of water, and some plants and animals are composed of up to 90% of water. Thus, water is an essential compound in the circle of life,... Continue Reading →
The tissues (groups of the same cells) in our body can be divided into two broad categories: those that are specialized and those that are not. Specialized tissues develop by cell differentiation in multicellular organisms. Unspecialized tissues, on the other hand, can be found in embryonic development in multicellular organisms. Since they are not yet... Continue Reading →
