Myth: A dead organism is the same as a nonliving thing in science.<br><br> Fact:<br><br> Evidence:
Ilya [14]

I recently did this assignment!

Instructions: Read each myth (untruth). Reword it to make a factual statement. Then, give two to three reasons why the myth is untrue. Use complete sentences and support your answer with evidence, using your own words.  

________________________________________

Answer:

Myth: A dead organism is the same as a nonliving thing in science.

o Fact: In science, dead is the same as nonliving.

o Evidence: Things that are nonliving never had the characteristics of life, and never will. Things that are dead once did have the characteristics of life, but when they die, they lose some of the characteristics. That is why dead and non-living are NOT the same thing.

Hope this helped!

Have an Amazing day!

Eddi Din [679]

Answer:

[CH₃OH] to decrease and [CO] to increase.

Explanation:

  • Since the energy appears as a product. So, the system is exothermic that releases heat.
  • Increasing the temperature of the system will cause the system to be shifted to the left side to attain the equilibrium again.
  • So, the right answer is:

<em>[CH₃OH] to decrease and [CO] to increase.</em>
