B - Because an active cell can only work if it has a 3-Dimension structure.
Yes that is the correct answer choice
Answer:
B. The tropospheric gases move becuase of convection currents.
Explanation:
The uneven heating of the regions of the troposphere by the sun ( the sun warms the air at the equator more than the air at the poles )causes convection currents, large-scale patterns of winds that move heat and moisture around the globe. In the Northern and Southern hemispheres, air rises along the equator and subpolar ( latitude about 50 to about 70 north and south ) climatic regions and sinks in the polar and subtropical regions. Air is deflected by the Earth's rotation as it moves between the poles and equator, creating belts of surface winds moving from east to west ( easterly winds ) in tropical and polar regions, the winds moving from west to east ( westerly winds ) in the middle latitudes. This global circulation is disrupted by the circular wind patterns of migrating high and low air pressure areas, plus locally abrupt changes in wind speed and direction known as turbulence.
Answer:
Atomic theory is the scientific theory that matter is composed of particles called atoms.
Solids: their molecules are close to each other.They can't change their shape nor they can does it expand to fill the entire available volume like gas.
Liquid: A liquid is an incompressible fluid that conforms to the shape of the container in which it is stored. It's molecules are not too close to each other.
Gas: Most gases cannot be seen but are present in the atmosphere.Their particles are far from each other.Gas is described by pressure, volume, temperature and number of particles
