Answer:
<u>Instead of Helium and Hydrogen there are heavier elements in inner planets like Nitrogen and oxygen.</u>
Explanation:
- As the inner planets like Mercury, Venus and Mars and earth have a solid surface which is separated by the Sharpe atmosphere, and their gravity is too low to hold these light gases.
- Uranus is primarily composed of gases and ice of which 83% is hydrogen and 15% helium and rest are trace gases. As in the early composition of the atmosphere, the inner planets like the earth had a solid atmosphere composed of solid silicates elements like magnesium, iron, calcium, and potassium.
- As the earth has a highly unstable atmosphere only carbon, nitrogen and oxygen combined in lightning occur. And planet mercury has no atmosphere thus gravity is too low to hold any gas.

<h2>
short definition:</h2>
<u><em> a species is a population or groups of populations that can potentially interbreed freely within and among themselves.</em></u>
<u><em /></u>
<em><u> Subspecies, are subgroups within a species that have different traits </u></em>
<h2>
long definition</h2>
<em><u>A species is a group of organisms that (in the case of sexually reproducing organisms) can freely interbreed, producing fertile offspring. This definition has its problems, but overall, it encompasses the meaning of the word “species” in biology.</u></em>
<em><u></u></em>
<em><u>A subspecies is, as the name implies, a smaller population within a species that share a particular common trait. Usually a sub species is at least partially genetically isolated from it’s parent species, so that interbreeding is less likely to occur. Most often a sub species is physically separated from the rest of the species, and may have some specific physical differences from the rest of the species. However, they are still able to interbreed with members of the parent population.</u></em>
Answer:
This statement is true
Explanation:
Cellular respiration uses the ingredients of glucose and oxygen to create water along with energy and carbon dioxide. However, for photosynthesis, it is the opposite. In photosynthesis water, energy, and carbon dioxide are the ingredients needed to produce to reactants of glucose and oxygen. Hope this helps!
