While it's true that Fossils hardly even contain DNA, they can still provide numerous clues in order to identify and verify an organism.
For example, in terms of Dinosaurs, their bones and fossils have provided enough evidence to provide an evolutionary link with modern birds.
Carbon dating is another way to find the age of a fossil which provides more information on it's surrounding habitat and the animals it interacted with.
B it will be exactly 100 grams
Both photosynthesis and respiration require specific catalyst.
Why not the other answer?
(1) only photosynthesis require the sun as a source of energy,respiration use glucose.
(2) photosynthesis result in the formation of glucose,respiration result in the formation of carbon dioxide.
(3)Only respiration occur in the mitochondria,photosynthesis occur in the stroma of the chloroplast.
Answer is 2 because both of them require specific enzyme and as you know enzymes are biological catalyst.
