<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:
Carbon dioxide and water; organic molecules and oxygen; chemical potential; usable chemical energy in the form of ATP; heat energy that cannot do work
<u>Explanation</u>:
- Cellular respiration produces <u>carbon dioxide and water</u> from <u>organic molecules and oxygen</u>; organic molecules are a source of <u>chemical potential energy</u> that cellular respiration transfers into <u>usable chemical energy in the form of ATP</u> and transforms into <u>heat energy that cannot do work</u>.
- <u><em>Cellular respiration</em></u> is a process that takes place in the mitochondria in living organisms cells. It is the powerhouse of a cell.
- <em><u>The process involves the break down of organic molecules such as glucose, in presence of oxygen, to generate energy in the form of ATP, which is the usable form of energy by the cells to drive processes such as transport, growth and development, etc.</u></em>
- The process converts chemical potential energy in organic compounds to usable chemical energy in the form of ATP. Carbon dioxide and water are also produced as by-products during the process.
Answer:
A. First incubation at 37 Celsius; second at room temperature
Explanation:
When you are sick for some sort of infection your body will raise your body temperature to kill the infection (bacterias, viruses). 37 C it's normal temperature and those pathogens can easily grow up (very fast). 15 minutes it's enough to promote the bacteria reproduction at 37 C, to decelerate you need to change the temperature (a lower one just to decrease the reproduction rate).
Having a low rate reproduction of bacterias it's fine for your culture media, it will last for more time than a culture media with 37 Celsius all the time.
