.Answer:

Option A, fix nitrogen inside nodules on the roots of legumes

Explanation:

Rizhobium bacteria live in symbiotic relationship with roots of leguminous plants such as pulses including alfalfa, soybean etc.

Rhizobium or Bradyrhizobium  is a gram negative bacteria that satisfies the nitrogen starvation of host plant.  

These bacteria get habitation and nutrition from these leguminous plants and in return they fix the nitrogen into the nodules of the roots. This is a kind of facultative association between soil bacteria rizhobium and legume plants.  

Hence, option A is correct

Thus, option A is correct

Which one of the following statements about the troposphere is
Dvinal [7]

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.

HEYYYYYYYYYY PLEASE HELP!!!!!

Answer:

Velocity

Explanation:

Given the change in positive (direction) over time we are given the velocity formula.

V = Change in direction/Change in time

Since we are given a direction we can rule out speed as well as direction in itself. We can also rule out acceleration because that is the change in Velocity divided by change in time.
