Answer:
Write the speech, then read it and revise over and over.
Explanation:
Whenever preparing for a speech, the most important thing is to make sure that whatever you want to express or talk about in the speech are included. It need not necessarily be the perfect or full-fledged composition of the speech, but rather mention the main points first.
It is always preferable to write down the speech so that there can be revisions and alterations done before finalizing it. The first draft can be sketchy, even rough, but that's what makes it the first draft. It need not be a complete and correct speech at the first attempt. But more important than that, it is <u>best to write down the speech, read it over and over again, make revisions and then make changes wherever necessary.</u>
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)
