The belief was that there was a distinct order of living things: Chinese, barbarians, and beasts. That's why they made all foreign diplomats bow down to the Emperor and why they completely isolated the country to show that it's self sufficient.
The answer is D.
Did you find an answer? I need help on that one too.
When i cycle to school every morning,
i dream of many things
and then the wind will whisper,
to take me on its wings,
i will fly to see all of the beauty
of nature and human beings,
the love of magic wonders
give kisses to every little thing
the sun shines thru ' bits of clouds
the rays will fall on me,
the skys will put its beauty out;
before my eyes to see.
O' such a pleasant smell of school
as i fly towards the door'
with joy and full of heart
to be there to study more
for the start.
Answer:
Gas
carbon
dioxide
Relative Abundance
trace gas
Description
required for photosynthesis
Gas
nitrogen
Relative Abundance
most abundant gas in the atmosphere
Description
incorporated as a major component of proteins and DNA
Gas
oxygen
Relative Abundance
second most abundant gas in the atmosphere
Description
required for aerobic cellular respiration
Explanation:
Carbon dioxide (CO2) gas is only 0.04% by volume of the atmosphere. So, it is found in trace. It is used by plants and some cyanobacteria and algae in photosynthesis for preparing food in the presence of light/
Nitrogen (N2) gas is about 78% by volume of the atmosphere, and hence it is the most abundant gas in the atmosphere. It is a major component of proteins (as amino acids) and DNA (as nucleic acids).
Oxygen gas (O2) is about 28% by volume of the atmosphere; hence it is second most abundant gas after nitrogen gas.
Aerobic cellular respiration is a process in which food particles are broken down by oxygen for the release of energy in the form of ATP (adenosine triphosphate)
