Explanation:
Answer:
c. Ribs move out- diaphragm contracts- lungs expand- decrease intrathoracic pressure
Explanation:
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.
The correct option is this: THE TROUTS GROW FASTER BUT HAVE SHORTER LIFE SPAN.
Trouts live in fresh waters such as streams and lakes, they feed on microscopic organisms, small fish and insects. They have a maximum length of about 35 inches and they are excellence sources of omega 3 fatty acids. Trouts have relatively short life span.
The first one is going to be b and the second one is going to be a
