Answer:
a) Thigmotropism
b) Phototropism
c) Gravitropism
Explanation:
A) the turning or bending of a plant or other organism in response to a touch stimulus. example: the folding movement of the Mimosa pudica leaflets, can be considered as an example of thigmonastism.
B) the orientation of a plant or other organism in response to light, either towards the source of light ( positive phototropism ) or away from it ( negative phototropism ).example: Sunflower is a highly phototropic plant. They grow towards the sun and are also seen tracking the movement of the sun throughout the day. That is, the flower keeps changing its direction with the movement of the sun. Sunflower requires more light for its growth and survival.
C) The gravity-directed growth process, called gravitropism, dictates upward shoot growth to ensure a proper positioning of the leaves for efficient photosynthesis and gas exchange. example: tree has fallen over and due to gravitropism exhibits this arched growth.

Answer:
The correct option is D. Cow dung would have piled up in Australia.
Explanation:
The native beetles of Australia did not feed on the dung from the non-native cattle. As the cattle were imported from another country, the native beetles did not recognize the texture of the dung and hence, did not feed on them. As a result, cow dung started to pile up. To get rid of the dung, the best possible solution was to import beetles from a different country which recognized the texture of the dung and could feed on it.
The answer is pollution.
Groundwater is water under the surface of the Earth which is widely used as a source of freshwater. Thanks to its position, it is <span>not as much vulnerable to pollution such as surface water. However, some leaking of landfills, septic systems and agricultural chemicals that can reach it deep down under the surface can cause groundwater pollution.</span>
