Answer:
Prokaryotes do not have a nucleus; eukaryotes have a nucleus
Explanation:
Work done= <span>force x distance moved in the direction of that force so: 200 x 15 = 3000J=4kJ</span>
Answer:
D. hot, but much cooler than at a hydrothermal vent
Explanation:
A cold seep is an area in the ocean floor where hydrogen sulfide, methane and other hydrocarbon rich fluids seep through thus forming a brine pool.
A cold seep is also called a cold vent and its temperature is not necessary lower than that of the surrounding water, but it is lower than that of a hydrothermal vent which is about 60 °C.
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.
