Answer:
B. carbon dioxide is the correct answer.
Explanation:
The greenhouse effect is caused by human activities like cutting the forest and fossil fuel burning, increase the level of carbon dioxide gas(greenhouse gases) and creates global warming.
When the fossil fuel is burned carbon combines with oxygen to form Carbon dioxide and it increases the concentration of greenhouse gases and give rise to global warming.
The Greenhouse gases Carbon dioxide traps the radiating heat from the Earth, this heat is absorbed in the form of infrared radiations and the radiation is emitted which warmer the lower atmosphere and Earth surface,this result in melting of ice sheets, glaciers and warming the ocean
Thus carbon dioxide greenhouse gases which creates global warming.
Energy transformation is the process of transfer and conversion of energy from one species to another. None of the above is not an example of energy transformation. Thus, option D is correct.
Energy transformation is the process in an ecosystem that includes the conversion of energy from one level to another in the food chain or the metabolic reactions.
Photosynthetic reactions under the sun, herbivores feeding on producers, and predators feeding on the primary consumers are examples of energy conversion as it is continuously passing the energy to another species in the ecosystem.
Therefore, none of the above is not an example of energy transformation.

Answer:
D. None of the above
Explanation:
Although many cells go through both anaphase A and B motions, occasionally one motion takes precedence over the other. Poleward migration in anaphase requires the separation of the paired sister chromatids. The components that link the chromatids at the centromere are degraded by proteolysis, which causes chromatid separation.
Synapsis is the name given to this action. Crossing over happens during synapsis. DNA is transferred between two nonsister chromatids of a homologous pair of chromosomes during crossing over.
When nondisjunction occurs, the homologous or sister chromatids are drawn to one pole of the cell because the separation does not take place.
Therefore, One daughter cell would have more chromosomes than usual, and one sister chromatid would not split equally during the anaphase of mitosis.
