Navigating the Challenges of IB Biology

Challenges of IB Biology

The International Baccalaureate (IB) Biology course is renowned for its rigorous curriculum and the comprehensive understanding of biological concepts it demands. Students often find themselves grappling with the depth of content and the necessity for strong analytical skills. These challenges can be daunting, but they also set the stage for a rewarding academic journey. This … Read more

Scientific Method

Scientific Method

Definition It refers to a set of processes that people can use to gain knowledge about the world around them, improve that knowledge, and explain why and/or how things happen. By using this method, observations are made, questions are formulated, hypotheses are formed, experiments are conducted, data is analyzed, and a conclusion is reached.  In … Read more

Chlorophyll

Chlorophyll

Chlorophyll Definition Chlorophyll is a molecule produced by plants, algae and cyanobacteria which aids in the conversion of light energy into chemical bonds. Chlorophyll is known as a pigment, or molecule that reflects some wavelengths of light, while absorbing others. Pigments produce a variety of colors in the plant and animal world. Chlorophyll is a … Read more

Embalming

Embalming

Embalming Definition Embalming refers to the preservation of human remains via inhibiting decomposition with the use of chemicals for the purpose of medical education or social reasons (e.g., funeral service). Embalming involves the preservation of the entire human body, and is associated with three goals: Sanitization: Sanitizing the body during embalming involves washing the body … Read more

Law of Independent Assortment

Law of Independent Assortment

Law of Independent Assortment Definition The Law of Independent Assortment states that different genes and their alleles are inherited independently within sexually reproducing organisms. During meiosis, chromosomes are separated into multiple gametes. Genes linked on a chromosome can rearrange themselves through the process of crossing-over. Therefore, each gene is inherited independently.   Law of Independent … Read more

Cytoskeleton

Cytoskeleton

Cytoskeleton Definition The cytoskeleton is a network of filaments and tubules that extends throughout a cell, through the cytoplasm, which is all of the material within a cell except for the nucleus. It is found in all cells, though the proteins that it is made of vary between organisms.  The cytoskeleton supports the cell, gives … Read more

Phosphate Group

Phosphate Group

Phosphate Group Definition One phosphorus atom and four oxygen atoms make up the chemical compound phosphate, PO43-. A phosphate group is formed when it attaches to a carbon molecule. In addition to DNA and RNA, adenosine triphosphate (ATP) provides energy to cells.  Cell membranes are made up of phospholipids, which are formed by phosphotates. Especially … Read more

Nerve Cell

Nerve Cell

The adult human brain contains around 86 billion neurons, the basic functional units of the nervous system. Nerve cells transmit information to other cells after receiving it from other cells. In the human body, there are three different types of nerve cells that detect and interpret information about our external environment before responding to it.  … Read more
