Transpiration is a process by which plants absorb water through their roots and then release it through tiny pores in their leaves and stems. It is an important part of the water cycle and helps to keep plants hydrated. The tissue in plants that is directly involved in carrying out transpiration is called the stomata. …

Respiration is a fundamental process in the human body, and it is highly regulated by a number of different processes and stimuli. Many physical and physiological events can either increase or decrease respiration, and it’s important to understand which events are associated with which effects. Here, we’ll explore some of the factors that influence respiration …

? Humans start out as a single cell, but by the time they are born, they consist of trillions of cells with very different functions. But how is it that one cell can become a brain cell and another a skin cell? The answer lies in a process called differentiation. What Is Differentiation? Differentiation is …

? A transcription factor is a special type of protein that binds to DNA and helps control the activity of a gene. Transcription factors play a crucial role in cellular processes, and their activities can cause long-term, even permanent, changes in a cell’s behavior. Transcription factors can be activated in several different ways, so let’s …

Evolutionary change is the process by which species change over time as a result of natural and artificial selection. It is the major force behind the diversity of life on earth, and is the foundation of the theory of evolution. Evolutionary change occurs in many different ways, but there are some general causes that are …

The Allee effect is an important concept in population and community ecology, which states that a population can only persist if it is sufficiently large, i.e. it has a certain minimal population size. Below are some examples of an Allee effect in nature: Social Species: For social species such as primates, the Allee effect includes …

An epitope is a fragment of a larger molecule, usually a protein, that is recognized by the immune system. The recognition involves the binding of a protein (or peptide) from an antigen to a specific binding site on an antibody molecule. Epitopes on a protein can be linear or conformational and can be found anywhere …
