Deca is the prefix that describes a molecule with 10 atoms of the same element.
Convergent boundary I think
Answer:
Seafloor spreading helps explain continental drift in the theory of plate tectonics. When oceanic plates diverge, tensional stress causes fractures to occur in the lithosphere. At a spreading center, basaltic magma rises up the fractures and cools on the ocean floor to form new seabed.
Explanation:
Seafloor spreading occurs at divergent plate boundaries. As tectonic plates slowly move away from each other, heat from the mantle's convection currents makes the crust more plastic and less dense. The less-dense material rises, often forming a mountain or elevated area of the seafloor. Eventually, the crust cracks.
Answer:
D. A and B
Explanation:
Some <em>Apis mellifera </em>bees genetically inherit the hygienic behaviour to remove the dead and diseased larvae from beehives by uncapping the sealed cells. This activity maintains the overall health of the bee colony by protecting it from unwanted pests and pathogenic diseases. Usually both hygienic and non hygienic bees survive well.
Here, in hot summer many bees had perished due to disease and hot climate. Accumulation of dead larvae in hives of non hygienic bees would have invited more pathogens and created infectious conditions in summer. Hence their hives could not survive. Now the remaining hygienic bees will mate with each other and the offspring will have more chances to be born with the hygienic trait. Hence the frequency of alleles determining this trait will increase in this population. This would also be an example of natural selection as hygienic bees were preferred by the nature over non hygienic ones to survive in hot season.
