Joshua saw the rising batter form the cake in the oven. What Joshua
observed was because of the<span> reaction of baking soda or baking
powder with the liquid in the batter: These ingredients react together
and cause air bubbles to form. Baking powder contains sodium hydrogen carbonate
that breaks down when heated, releasing carbon dioxide that helps cake mixtures
to rise during baking.</span>
In addition the oxygen in the Earth's atmosphere absorbs wavelengths at the edge of the ultra-violet region of the spectrum. The resulting color, which appears like a pale blue, actually is a mixture of all the scattered colors, mainly blue and green.

<span>CCA stands for chromated copper arsenic. CCA is a wood preservative, which is in use since 1930. copper is the protective structure and arsenic is the insecticide used. Arsenic serves no purpose in protecting the timber, but it is the binding agent of other 2 chemcals.
The best argument in terms of science would be , not to remove CCA- treated wood from the existing building structure. this wood preservative was banned due pressure from common and not scientific reason. The concern was on arsenic exposure. The exposure level of arsenic from the treated wood is far below fatal levels , than it could be seen in diet and drinking water. Hence doesn't harm children. A research also shows that after 45 years of treatment the exposure level is almost nil. Hence it is safe to have a CCA treated woods at home.</span>
Answer:

Explanation:
Answer:
All the things expect enegry are recycled.
Explanation:
- When the decomposer decomposes the organic substances than they are taken by plants in the form of nutrition and minerals. Likewise, the food prepared by the plants are taken by animals and the nutrition is recycled.
- The oxygen and carbon dioxide cycle is also recycled. When the animals releases carbon then the plants take it and gives out the oxygen. In this way oxygen and carbon dioxide cycle is also maintained in nature.
But incase of enegry it cannot be recycled but frequently transfered from one form to another form.
