Answer:
1. In the dispersive model, each strand of both daughter molecules contains a mixture of old and newly synthesized DNA, and in the semiconservative model, each new double helix consists of one old and one new strand.
Explanation: it helps to remember that dispersive means to disperse your DNA molecules! And semi conservative means you keep one of your old strands! Hope this helps!
True
Explanation:
The ocean conveyor belt explains the cyclic nature of global water round the globe.
It suggests that cold denser water circulates and moves downward whereas warm water rises.
- The great ocean conveyor belt shows that the world's ocean is constantly circulating and mixing.
- At high latitude where temperature is low, warm water from around the equator where the sun is over head loses heat to warm the atmosphere.
- As they lose heat, they become colder and denser.
- They then sink and begin to flow southward where they get heated and rise.
- This conveyor belt is driven by salinity and temperature differences.

Answer:
D
Explanation:
Vegetation on soil protects the soil from erosion because its roots and root hairs help bind the soil particles together. This occurs mechanically by binding soil into crumbs and also chemically by providing organic matter that binds the soil particle into humus that holds moisture. The soil becomes heavy to be carried off by wind erosion. Trees also break the down flow of water hence reducing the capacity of runoff to carry soil sediments.
