This observation can be explained by the theory of endosymbiosis. From what scientists have discovered, it can be explained that the double membrane of both chloroplast and mitochondria are as a result of them been subjected to phagocytosis but they were not digested. Their DNA suggest that they were once free living prokaryotes. This agree with the endosymbiosis theory which states that eukaryotic cell organelles developed from prokaryotic cells.
I think Its the option that says that one of the reactions absorbed more energy because in the diagram the activation energy is shown to be greater for the blue pathway.
Adaptations are
the result of evolution in different living organisms. This process occurs amazingly
through gene mutation but it takes a very long period in time. Adaptation
processes occur to help species survive and thrive in the ecological balance of
life. Structural adaptations are physical features of an organism that adapted
through time. An example of this are the bills of a bird and the fur of bears
that they generally need for their survival; birds for hunting, and bears to
protect them from low climate areas.

Functional or
Behavioral adaptations refer to particular things that an organism or organisms
do to survive. In the example above, behavioral adaptations that birds do is
through certain bird calls and migration, while bears hunt during warmer
seasons and hibernate during winter season. </span>
A section of DNA that provides info for a protein is called a Gene
Answer:
Without "Green house Gases" the earth would be way too cold for humans, animals, plants, and many more things to survive. We need the earth warm enough so we are not cold! Without green house gases, there would be no warm month, there would just be nothing but cold months year round!
Does this help?
