Brassicaceae
The family Brassicaceae, also known as Mustard or Cruciferous plants, is a large and diverse group of flowering plants commonly found in temperate and subarctic regions. It includes many species of plants, such as broccoli, cabbage, cauliflower, kale, mustard, turnips, rutabaga, and collard greens, among many others. These plants are characterized by the presence of four or six petal-like structures, known as petals, in their flowers, as well as by their capacity to form an enzyme called glucosinolate in their leaves, stems, and flowers.
Bronchitis
Bronchitis is a medical condition characterized by inflammation of the bronchial tubes, which are the airways that carry oxygen to the lungs. It is often caused by a bacterial or viral infection and can cause symptoms such as coughing, wheezing, chest tightness, and shortness of breath. There are two main types of bronchitis: acute and chronic. Acute bronchitis is a short-term infection that usually goes away on its own with rest and medication, while chronic bronchitis is a long-term condition that can lead to further lung damage and complications if left untreated.
Caenorhabditis
Caenorhabditis is a genus of nematode worms that is widely used as a model organism in scientific research, particularly in the fields of genetics, developmental biology, and neuroscience. The most well-known species in this genus is Caenorhabditis elegans, which is a small, soil-dwelling worm that is often used to study the biology of aging, behavior, and disease.
Calcitonin
Calcitonin is a hormone produced by the thyroid gland and also by certain tissues in response to high levels of calcium in the blood. It works to lower blood calcium levels by inhibiting the release of calcium from bones and increasing the excretion of calcium in the urine.
Cannabaceae
The Cannabaceae family is a group of flowering plants that includes hemp, mangroves, and hops. It is a relatively small family of about 100 species of plants, mostly found in tropical and subtropical regions. The plants in this family are characterized by their characteristic growth habit, which is often shrub-like or vine-like.
Capitate
Capitate refers to a shape resembling a top or dome, typically rounded and flat at the top. In anatomy, the capitate bone is a small round bone in the wrist. Additionally, it can also mean to head or crown, as in "capitate the mountain with a statue".
Capsule
A capsule is a small, usually rigid or semirigid, hollow container, typically made of plastic or metal, that is used to hold or enclose something, such as a medication, a flavoring, or a spice. Capsules can be used in various fields, including medicine, food, and engineering.
Catabolism
Catabolism is the process of breaking down or decomposing complex molecules into simpler ones, often releasing energy in the form of heat or movement. It is the opposite of anabolism, which is the building up of complex molecules. In biology, catabolism is an important process that helps the body get energy from the food we eat, by breaking down carbohydrates, proteins, and fats into simpler compounds that can be used to fuel our cells and tissues.
Catalyst
A catalyst is a person or thing that precipitates an event or change, often without being directly involved in the outcome. It is an agent that accelerates a chemical reaction or influences the course of events in a significant way.
Caveolae
Caveolae (pronounced kah-vee-oh-lee) are small, flask-shaped pouches or vesicles in the plasma membrane of many cells, particularly in endothelial cells and smooth muscle cells. They are involved in the regulation of cell signaling, cholesterol transport, and cell adhesion. Caveolae can also act as docking sites for certain proteins and lipids, facilitating their entry into cells. They are about 50-100 nanometers in diameter and were first described in the 1950s by Dr. Joseph Goldstein.
Cellulose
Cellulose is a type of complex carbohydrate found in the cell walls of plants. It is the most abundant organic compound found in nature and is a key component of plant cell walls, making up about 50% of the biomass of all living organisms. Cellulose is also the main component of paper, cardboard, and many textiles, such as cotton. It is a highly crystalline, insoluble, and inert substance, and it is highly resistant to acid digestion, which makes it difficult to break down by most animals, except for certain microorganisms such as bacteria and fungi.
Centromere
The centromere is a specialized structure found in the center of a chromosome that plays a crucial role in its segregation during cell division. A centromere is typically a constricted region of the chromosome where the two sister chromatids are attached. It acts as a docking site for the spindle fibers, which pull the sister chromatids apart during mitosis and meiosis, ensuring that each new cell receives a complete set of chromosomes.
Cerebrum
The cerebrum is the largest part of the human brain, responsible for processing sensory information, controlling movement, and managing higher-level cognitive functions such as thought, emotion, and memory. It is divided into two hemispheres, the left and right, each with distinct functions, with the left hemisphere dealing more with language and logic, and the right hemisphere with spatial awareness and creativity.
Chemotaxis
Chemotaxis is the movement of cells, organisms, or particles towards or away from a specific chemical substance, often in response to its concentration gradient or chemical signal. In other words, chemotaxis is a biological phenomenon where cells or organisms navigate their environment towards a source of chemicals that stimulate them or away from those that repel them. This movement is essential in various biological processes, such as finding food, mates, or escaping from danger.
Chimera
A chimera is a mythological creature composed of the physical parts of multiple animals, typically a lion, a goat, and a serpent. In modern usage, a chimera can also refer to something that is composed of disparate parts, such as a concept, idea, or entity that is made up of diverse elements. In biology, a chimera is an individual organism that contains cells or tissues from two or more different individuals, often resulting from organ transplantation or embryo mixing.
Chimeric
Chimeric refers to something that is composed of multiple disparate parts or elements, often in a way that is unusual, illogical, or unnatural. This can apply to physical structures, shapes, or combinations, as well as abstract concepts, ideas, or entities.<br><br>In biology, a chimera is a creature that is composed of cells or tissues from two or more different individuals, often resulting from a genetic mutation or the combining of genetic material from different sources.<br><br>More broadly, chimeric can describe anything that is hybrid, composite, or artificial, often in a way that blurs boundaries or defies categorization. Examples might include a cityscape with a futuristic skyscraper nestled among ancient buildings, a piece of art that combines opposing styles, or a political system that blends different ideologies.
Chitin
Chitin is a type of polysaccharide, a complex carbohydrate, found in the exoskeletons of crustaceans, insects, and some mollusks. It is a major component of the cell walls of fungi and provides strength and rigidity to their cell walls. Chitin is similar in structure to cellulose, a polysaccharide found in plant cell walls, but has a slightly different molecular structure. It is also found in the shells of some microorganisms, such as bacteria and archaea.
Chlorophyll
Chlorophyll is the green pigment found in plants, algae, and cyanobacteria that plays a crucial role in photosynthesis. It absorbs light energy from the sun and uses it to power the conversion of carbon dioxide and water into glucose and oxygen. Chlorophyll is responsible for the green color of plants and its absence or reduction leads to the yellowing or bleaching of leaves.
Chloroplast
A chloroplast is a type of organelle found in plant cells that is responsible for photosynthesis, the process by which plants convert sunlight, carbon dioxide, and water into glucose and oxygen. Chloroplasts are like tiny factories inside plant cells that use energy from sunlight to produce glucose, which is used by the plant to fuel its growth and development.
Chondroblast
Chondroblast refers to a type of cell that plays a crucial role in the formation of cartilage. Chondroblasts are immature cells that differentiate into chondrocytes, which are the mature cells responsible for producing cartilage tissue.
Chordata
Chordata refers to a phylum of animals that includes vertebrates (animals with a backbone) and some marine animals that do not have a backbone, such as tunicates and lancelets. Chordates are characterized by the presence of a notochord (a flexible, rod-like structure that provides support and stiffness), a dorsal hollow nerve cord, pharyngeal slits, and a post-anal tail.
Chromatin
Chromatin refers to the complex of DNA and proteins that make up the chromosome of a cell. Chromatin is composed of DNA wrapped around a protein core, and when a cell is not actively using its genes, the chromatin is compacted into a more manageable structure called chromatin fiber.
Chromatograph
A chromatograph is a laboratory instrument used to separate, identify, and quantify the components of a mixture based on their physical and chemical properties, typically by carrying out a process called chromatography. In this process, a sample is dissolved in a mobile phase and carried through a stationary phase, where the different components of the mixture interact with the stationary phase in different ways, resulting in a separation of the components. Chromatographs are commonly used in fields such as pharmaceuticals, environmental monitoring, and food testing to analyze complex mixtures and identify specific compounds.
Chromosome
A chromosome is a thread-like structure made up of DNA and proteins that carries genetic information in the nucleus of living cells. It is made up of a long double helix of DNA wrapped around proteins called histones, and plays a central role in the development and function of all living organisms. In humans, there are 23 pairs of chromosomes, for a total of 46 chromosomes, in every cell of the body. Each chromosome has a specific set of genes that determine the characteristics of an individual.
Chronobiology
Chronobiology is the study of the internal biological processes that occur in living organisms in response to the cycles of nature, such as day and night, and the passage of time. It examines the ways in which organisms adapt to and are affected by these natural rhythms, and how these rhythms are influenced by various factors such as light, temperature, and social and environmental factors.
Chronotype
A chronotype is a person's natural sleep-wake cycle, or the timing of their daily rhythms, including peak alertness and sleepiness. It is also referred to as a person's "sleep-wake chronology".
Cladistics
Cladistics is a method of classification in biology that groups organisms based on shared derived characteristics, known as synapomorphies. It is a system of biological classification that focuses on the evolutionary relationships between organisms and reconstructs their phylogenetic tree. Cladistics aims to identify the most recent common ancestor of a group of organisms and the evolutionary relationships between them, providing a hierarchical classification system.
Cladogram
A cladogram is a diagram or graph that shows the relationships among a group of organisms, typically based on genetic or morphological data. It is a way to visualize how different organisms are related to one another in terms of their evolutionary history. In a cladogram, groups of organisms are represented by nodes or branches, and the relationships between them are represented by lines or edges.
Clathrin
Clathrin is a type of protein that forms a lattice-like structure around the membrane of a cell, creating a "cage" that helps to internalize molecules and other substances by budding off vesicles from the cell membrane.
Cochineal
Cochineal is a bright red or crimson dyestuff obtained from the insect Coccus cacti, commonly found on cacti and other plants in the Americas, and was widely used in the textile, food, and cosmetic industries before the advent of synthetic dyes. The insect was crushed and then mixed with an alkaline substance to release its pigment, which could be used to color fabrics, foods, and cosmetics. Cochineal was a highly prized and valuable commodity in ancient and colonial times, and its use is still restricted in some countries due to concerns about food safety and animal welfare.
Codon
A codon is a sequence of three nucleotides (bases) that code for a specific amino acid or a stop signal in a protein sequence. In other words, it is a triplet of RNA nucleotides that encode a particular genetic message.
Cohesion
Cohesion refers to the state of being united or stuck together. In a broader sense, it can also refer to the quality of being united or coherent in thought or action. In linguistics, cohesion refers to the ways in which a text is held together, such as through repetition, pronouns, and other linguistic devices. In social sciences, cohesion often refers to the sense of community and togetherness among individuals or groups.
Commensalism
Commensalism is a type of symbiotic relationship between two organisms, where one organism, the commensal, benefits from the relationship, while the other organism, the host, is not affected either positively or negatively. The commensal organism often obtains food, shelter, or other benefits from the host without harming or helping it.
Concentration
Concentration refers to the act of focusing one's attention on something, often eliminating distractions in order to achieve a specific goal or complete a task. It can be mental, aiming to concentrate on a thought or idea, or physical, such as maintaining mental focus while performing a physical activity.
Concrescence
Concrescence is a noun that refers to the act of growing or developing together, often used to describe the process of conjoining or fusing of particles, tissues, or organisms. In a broader sense, it can also imply the coming together of ideas, concepts, or entities. The term is often used in scientific contexts, such as biology, geology, and ecology, to describe natural processes like the formation of structures or the integration of different components within a system.
