Explanation:
Carbon dioxide is added to the atmosphere naturally when organisms respire or decompose (decay), carbonate rocks are weathered, forest fires occur, and volcanoes erupt. Carbon dioxide is also added to the atmosphere through human activities, such as the burning of fossil fuels and forests and the production of cement.
The light-independent reaction for obtaining energy (I think this is what you are talking about) occurs within the organism. This is because cellular respiration does not require light, seeing as how most humans do not need light directly (although they need the Sun for photosynthesis to occur in plants so that the plants produce Oxygen) in order to survive. Hopefully this helps!
Proteins are the macromolecules made of hundreds of amino acids. Proteins are most varied class of biological molecules and show the greatest variety of structures. Many have detailed three-dimensional folding patterns that result in a compact form, but others do not fold up at all and they are in random conformations. The function of proteins depends on their structure.
The secondary structure of protein fold together to form the 3D arrangement of a polypeptide chain that results into Tertiary structure which is a functional protein.
I'm pretty sure it's <span>both. Allopatric speciation occurs when there is a physical barrier formed like a mountain or river. and Sympatric speciation occurs when there is a genetic barrier formed like a mutation that causes a different mating season or preference in mate choice.
hope this helps!</span>
