High above the surface of the Earth, charged particles (such as electrons and protons) can become trapped in the Earth's magneti
c field in regions known as Van Allen belts. A typical electron in a Van Allen belt has an energy of 40 keV and travels in a roughly circular orbit with an average radius of 210 m. What is the magnitude of the Earth's magnetic field where such an electron orbits?
The transport of the solutes may occur along the concentration gradient or against the concentration gradient. Two main types of transport that occur in living organism are active process and passive process.
The passive transport do not require the energy for its transport whereas the active transport require energy. The K+ coupled transport do not require any energy molecule for its transport and easily transfer by the leaky channel. Hence, the K+-coupled transport is not the common active transport.
Binomial nomenclature<span> is the formal </span>naming system<span> for living things that all </span>scientists use<span>. It gives every species a two-part scientific name. For example, a ladybug found in the United States goes by the fancy name of Harmonia axyridis. The first part of a scientific name, like Harmonia, is called the genus.</span>
