The answer is d.their cells have some differences in the sequence of nucleotides in their nucleic acids
Human and mice is both mammals and have similar structure and metabolism. There should be no big differences in biological or organic molecule. The big differences should be the sequence of the nucleic acids in their DNA. Mice could produce similar protein in human, but the DNA is different.
<em />It's radiocarbon dating because in the previous question it says that she is trying to find the amount of carbon-14 and carbon-12 in the fossil
Answer:
During photosynthesis a plant absorbs light energy using the pigment chlorophyll. This allows it to convert carbon dioxide and water into glucose. This glucose is:
transported to the growing parts of the plant for use in respiration
transformed into cellulose, proteins and oils
turned into starch for storage
Therefore, to test if a plant has been photosynthesising, you can test the leaf to see if starch is present.
I'm having trouble on this too :(
