The International Baccalaureate (IB) Physics course is renowned for its rigorous curriculum and high expectations. Students who embark on this journey often find themselves challenged by the depth and breadth of the material. However, with the right study techniques, the rewards can be immense. Mastering IB Physics not only opens doors to prestigious universities but … Read more
Organisations all throughout the world are dealing with unpredictable crises. These problems may interrupt operations, strain resources, and even jeopardise an organisation’s very survival, ranging from unexpected market swings to unforeseen natural calamities. There has never been a greater need for leaders who can not only withstand the storm but also shepherd their teams and … Read more
Beta Oxidation Definition In beta oxidation, fatty acid molecules are broken down to produce energy through multiple steps. The beta oxidation process breaks down long fatty acids that have been converted into acyl-CoA chains into progressively smaller fatty acyl-CoA chains. As a result of this reaction, acetyl-CoA, FADH2 and NADH are released, the three of … Read more
Tissue Definition In tissue, cells have a similar structure and perform a specific function together. An old French verb means “to weave” is the origin of the word tissue. An animal’s tissues can be divided into four categories: connective, muscular, nervous, and epithelial. It is possible to divide plant tissues into three types: vascular, ground, … Read more
Trophic Level Definition A trophic level is the group of organisms within an ecosystem which occupy the same level in a food chain. There are five main trophic levels within a food chain, each of which differs in its nutritional relationship with the primary energy source. The primary energy source in any ecosystem is the … Read more
Dihybrid Cross Definition A dihybrid cross is an experiment in genetics in which the phenotypes of two genes are followed through the mating of individuals carrying multiple alleles at those gene loci. Most sexually reproducing organisms carry two copies of each gene, allowing them to carry two different alleles. Historically, an organism with parts from … Read more
What Are Peripheral Proteins Peripheral protein, or peripheral membrane proteins, are a group of biologically active molecules formed from amino acids which interact with the surface of the lipid bilayer of cell membranes. Unlike integral membrane proteins, peripheral proteins do not enter into the hydrophobic space within the cell membrane. Instead, peripheral proteins have specific … Read more
Polygenic Inheritance Definition Polygenic inheritance, also known as quantitative inheritance, refers to a single inherited phenotypic trait that is controlled by two or more different genes. In a system which differs from Mendelian Genetics, where monogenic traits are determined by the different alleles of a single gene, polygenetic traits may display a range of possible … Read more
Krebs Cycle Definition The Krebs Cycle, also called the citric acid cycle, is the second major step in oxidative phosphorylation. After glycolysis breaks glucose into smaller 3-carbon molecules, the Krebs cycle transfers the energy from these molecules to electron carriers, which will be used in the electron transport chain to produce ATP. Krebs Cycle Overview … Read more
Parenchyma Cells Definition In plants, parenchyma is one of three types of ground tissue. Ground tissue is anything that is not vascular tissue or part of the dermis (skin) of the plant. In contrast to collenchyma and sclerenchyma cells, parenchyma cells primarily consists of all of the simple, thin walled, undifferentiated cells which form a … Read more
