What is a group of organisms of the same species that occupy the same geographic place at the same time?
population – A group of organisms of the same species living in the same area at the same time, and which are capable of interbreeding.
What is the smallest unit of matter made up of protons neutrons and electrons?
atom: The smallest possible amount of matter which still retains its identity as a chemical element, consisting of a nucleus surrounded by electrons. proton: Positively charged subatomic particle forming part of the nucleus of an atom and determining the atomic number of an element.
What is an individual that consists of one or more cells?
A living thing, whether made of one cell (like bacteria) or many cells (like a human), is called an organism.
What do we call the smallest unit of matter or an organism?
A cell is the smallest unit of an organism that can perform all life’s processes.
What is the smallest unit in a cell?
The cell is the smallest structural and functional unit of living organisms, which can exist on its own. Therefore, it is sometimes called the building block of life. Some organisms, such as bacteria or yeast, are unicellular—consisting only of a single cell—while others, for instance, mammalians, are multicellular.
What is the smallest units of matter?
atom, smallest unit into which matter can be divided without the release of electrically charged particles. It also is the smallest unit of matter that has the characteristic properties of a chemical element.
What are three basic units of matter?
The term “atom” comes from the Greek word for indivisible, because it was once thought that atoms were the smallest things in the universe and could not be divided. We now know that atoms are made up of three particles: protons, neutrons and electrons — which are composed of even smaller particles, such as quarks.
What is a very small particle called?
Explain that all matter on Earth exists in the form of a solid, liquid, or gas, and that solids, liquids, and gases are all made of extremely tiny particles called atoms and molecules.
Is a Preon smaller than a quark?
One preon model started as an internal paper at the Collider Detector at Fermilab (CDF) around 1994. The momentum uncertainty of a preon (of whatever mass) confined to a box of this size is about 200 GeV/c, 50,000 times larger than the rest mass of an up-quark and 400,000 times larger than the rest mass of an electron.
What’s the smallest subatomic particle?
quark
Is an electron smaller than a photon?
the size of photons and electrons are same as mass,but electron is negatively charged particle and photon is the energy (quanta).
What is the heaviest subatomic particle?
Electrons
What happens when you split a quark?
As you pull two quarks apart, you invest more energy in the system (incidentally making it heavier, e=mc2 and all). The inside of the flux tube is (of course) in a state of flux, with gluons being created and annihilated, sometimes producing quark pairs.
What happens to the mass When a particle and its antiparticle come together?
For each basic particle of matter, there exists an antiparticle with the same mass, but the opposite electric charge. When a particle and its antiparticle come together, they both disappear, quite literally in a flash, as the annihilation process transforms their mass into energy.
What happens when a particle and its antiparticle collide quizlet?
Whenever a particle and its antiparticle meet they annihilate each other. Annihilation is the process by which mass is converted into energy, particle and antiparticle are transformed into two photons of energy.
