When the two waves meet, there are two possibilities:
1.If the waves were both in phase and moving in the same direction, then, the amplitude will double, this is called constructive interference.
2. If the two waves were exactly out of phase, then they will try to move the water surface in all directions, thus, no movement and the waves cancel out. This is called destructive interference.
Bio accumulation of DDT lead to bird eggs with weak shells and non viable offspring. The lethal effects of DDT on birds was first noted in 1950; scientists discovered that earthworm was accumulating the DDT pesticide and that the robins that were preying on the earthworms were been poisoned. Further research revealed that the chemical cause thinning of the egg shell and production of non viable offspring. The chemical has since been banned in USA.
The explanation is given below
<u>Explanation:</u>
Hawaii's Big Island:
Mountain barriers play a significant role in modifying the air masses and topography affects the distribution of precipitation.
The orographic effect takes place on Hawaii's Big Island (i.e) the rising air makes the windward side of the mountains rainy and leeward side of the mountains dry.
Island of Maui:
In the Island of Maui, the high mean of rainfall is found on the windward side of the mountain slopes and the low mean of rainfall is found on the leeward lowlands and on upper slopes of the highest mountains.
Of the following given choices;

b. landmark discrimination problem
c. double dissociation problem
d. single dissociation problem
The answer is; A
Temporal lobe which spans both cerebral hemispheres of the brain and below the lateral fissure is significant in interpreting sensory information. Its communication with the hippocampus is also vital for the long-term memory. There is a visual area in the temporal lobe that processes and interprets visual information from the eye hence one is able to recognize objects.
CO2 is returned to the atmosphere by all methods except photosynthesis.
Through photosynthesis, a plant actually takes CO2 from the atmosphere and produces oxygen in return.
