Answer:
All life on Earth consists of either eukaryotic cells or prokaryotic cells. Prokaryotes were the first form of life. Scientists believe that eukaryotes evolved from prokaryotes around 2.7 billion years ago.
The primary distinction between these two types of organisms is that eukaryotic cells have a membrane-bound nucleus and prokaryotic cells do not. The nucleus is where eukaryotes store their genetic information. In prokaryotes, DNA is bundled together in the nucleoid region, but it is not stored within a membrane-bound nucleus.
The nucleus is only one of many membrane-bound organelles in eukaryotes. Prokaryotes, on the other hand, have no membrane-bound organelles. Another important difference is the DNA structure. Eukaryote DNA consists of multiple molecules of double-stranded linear DNA, while that of prokaryotes is double-stranded and circular.

Answer:
Chlorophyll a is the chief pigment associated with photosynthesis. As we can see,chlorophyll a absorbs red and blue wavelengths to a higher extent. Green light isn't rejected but rate of photosynthesis is more with red and blue wavelengths of light.
Explanation:
The spectral absorbance of photosystems and chloroplasts is lowest for green light...
All plants, however, has chlorophyll a, which absorbs most strongly at ~450 nm, or a bright blue color.
The carbon model is the flow and the movement of the carbon and its compound in the atmosphere. Climate change is the limitation of the carbon model.
<h3>What is climate change?</h3>
A climate change is a variation in the weather and the climate pattern due to a change in temperature and other atmospheric factors. It will lead to a transformation in the flow of carbon in the environment.
Increased carbon in surroundings increases temperature and results in a change in seasons and humidity levels, leading to changes in the rainfall.
Therefore, climate change is the limitation of the carbon model.
