biology The research study of living things. The researchers who study them are referred to as biologists.

cell The tiniest structural and practical system of an organism. Usually too little to see with the unaided eye, it includes a watery fluid surrounded by a membrane or wall. Depending upon their size, animals are made from anywhere from thousands to trillions of cells.

chemical A compound formed from 2 or more atoms that join (bond) in a repaired percentage and structure. For instance, water is a chemical made when 2 hydrogen atoms bond to one oxygen atom. Its chemical formula is H 2 O. Chemical likewise can be an adjective to explain residential or commercial properties of products that are the outcome of different responses in between various substances.

coworker Somebody who deals with another; a colleague or employee.

agreement To trigger muscle by permitting filaments in the muscle cells to link. The muscle ends up being more stiff as an outcome.

establish(in biology) To grow as an organism from conception through their adult years, frequently going through modifications in chemistry, size and in some cases even form.

developmental( in biology) An adjective that describes the modifications an organism goes through from conception through their adult years. Those modifications frequently include chemistry, size and in some cases even form.

diaphragm( in biology) The muscular wall in mammals that separates the thorax from the abdominal area. In breathing, its contractions open the thorax, pumping up the lungs.

dissection The act of dismantling something to take a look at how it is created. In biology, this suggests opening animals or plants to see their anatomy.

electrical power A circulation of charge, normally from the motion of adversely charged particles, called electrons.

electrical capacity Frequently referred to as voltage, electrical capacity is the driving force for an electrical existing (or circulation of electrons) in a circuit. In clinical terms, electrical capacity is a procedure of the prospective energy per system charge (such as electron or proton) kept in an electrical field.

fiction( adj. imaginary) A concept or a story that is fabricated, not a representation of genuine occasions.

field A location of research study, as in: Her field of research study was biology

gene( adj. hereditary) A section of DNA that codes, or holds directions, for a cell’s production of a protein. Offspring acquire genes from their moms and dads. Genes affect how an organism looks and acts.

cardiovascular disease Irreversible damage to the heart muscle that takes place when several areas of it end up being starved of oxygen, normally due to a short-lived obstruction in blood circulation.

hypothesis( v. assume) A proposed description for a phenomenon. In science, a hypothesis is a concept that should be carefully checked prior to it is accepted or turned down.

uncontrolled An action that is refrained from doing purposefully.

ion( adj. ionized) An atom or particle with an electrical charge due to the loss or gain of several electrons. An ionized gas, or plasma, is where all of the electrons have actually been separated from their moms and dad atoms.

lightning A flash of light set off by the discharge of electrical power that takes place in between clouds or in between a cloud and something in the world’s surface area. The electrical current can trigger a flash heating of the air, which can produce a sharp fracture of thunder.

mammal A warm-blooded animal differentiated by the ownership of hair or fur, the secretion of milk by women for feeding their young, and (usually) the bearing of live young.

membrane A barrier which obstructs the passage (or circulation through) of some products depending upon their size or other functions. Membranes are an essential part of filtering systems. Lots of serve that exact same function as the external covering of cells or organs of a body.

muscle A kind of tissue utilized to produce motion by contracting its cells, referred to as muscle fibers. Muscle is abundant in protein, which is why predatory types look for victim consisting of great deals of this tissue.

nerve A long, fragile fiber that transfers signals throughout the body of an animal. An animal’s foundation consists of lots of nerves, a few of which manage the motion of its legs or fins, and a few of which communicate feelings such as hot, cold or discomfort.

nerve system The network of afferent neuron and fibers that transfers signals in between parts of the body.

neurology A research study field that studies the anatomy and function of the brain and nerves. Individuals who operate in this field are referred to as neurologists (if they are medical physicians) or neuroscientists if they are scientists with a PhD.

organ( in biology) Numerous parts of an organism that carry out several specific functions. For example, an ovary is an organ that makes eggs, the brain is an organ that understands nerve signals and a plant’s roots are organs that take in nutrients and wetness.

phenomenon Something that is unexpected or uncommon.

physics The clinical research study of the nature and residential or commercial properties of matter and energy. Classical physics is a description of the nature and residential or commercial properties of matter and energy that counts on descriptions such as Newton’s laws of movement. Quantum physics, a discipline that emerged later on, is a more precise method of discussing the movements and habits of matter. A researcher who operates in such locations is referred to as a physicist.

physiologist A researcher who studies the branch of biology that handles how the bodies of healthy organisms work under typical situations.

scalpel A kind of unique knife utilized to open the body, normally to carry out surgical treatment.

skeletal muscle Muscles that assist an animal relocation and whose motions can be directed willingly. (The heart, likewise a muscle, moves involuntarily.)

types A group of comparable organisms efficient in producing offspring that can endure and replicate.

spine A round package of nerve fibers and associated tissue. It is confined in the spinal column and links almost all parts of the body to the brain, with which it forms the main nerve system.

tissue Made from cells, it is any of the unique kinds of products that comprise animals, plants or fungis. Cells within a tissue work as a system to carry out a specific function in living organisms. Various organs of the body, for example, frequently are made from several kinds of tissues.

voltage A force connected with an electrical current that is determined in systems referred to as volts. Power business utilize high-voltage to move electrical power over fars away.
