Explanation:

The skeletal structure of an organic compound is the series of atoms bonded together that form the essential structure of the compound. The skeleton can consist of chains, branches and/or rings of bonded atoms. Skeletal atoms other than carbon or hydrogen are called heteroatoms(Wikipedia).

Skeletal structures often involve only lines that represent carbon atoms. Hetero-atoms are often shown explicitly in skeletal structures. The skeletal structure of 7-tert-Butyl-3,5-diethyldecane has been shown in the image attached to this answer.

Desertification is an environmental problem that is most associated with the African Sahel. Hence, option A is appropriate.

Desertification is a form of dryland land degradation in which biological productivity is lost as a result of innate processes or as a result of human-induced activities, causing productive areas to become a rider and arider.

Desertification is the process through which grasslands and shrublands in drylands, also known as arid and semi-arid lands, decline and eventually vanish. Desertification can be attributed to two main factors: climate change and human activity.

Drylands are degraded by desertification. It entails the decline of croplands, pastures, and woods' biological economic productivity, and complexity. Climate variability with unsustainable human activity is the main cause.

Four levels of desertification—slight, moderate, severe, and extremely severe—have been utilized as the basis for the classification system used to create continental desertification maps.

Hence, option A is appropriate.

Answer:

Drought is a condition, not a hypothesis. Drought is the lack of rain, or evaporation in excess of precipitation.

The CAUSE of drought is a multi-pronged hypothesis. It can be due to cyclic changes in ocean temperature (El Niño/La Niña). It can be due to rain shadow downwind of a mountain range. It can be due to fluctuations in the sun’s brightness. It can be the result of urban sprawl and resulting shifts in upwind evaporation/transpiration. It can be the result of climate bands shifting in response to changing atmospheric composition. It can be the result of agricultural practices upwind. It can be just bad luck, with a location consistently not being the whatever-percent chance of where it’s raining.
