Answer:
The correct answer is option (D) there was a time in Pennsylvania history when dinosaur existed.
Explanation: A paleontologist discovers a rock slab on which the footprints of a Pennsylvania dinosaur are well preserved. This means that there was a time in Pennsylvania history when dinosaur existed in this area. Here fossil is a fragment of rock on which the footprints of dinosaur is present.
Mike discovered that the product of cellular respiration are the raw materials of Photosynthesis while the products of photosynthesis served as the raw materials for cellular respiration.
He also discovered that respiration is a catabolic process while photosynthesis is an anabolic process.
Another interesting fact seen by Mike is, the respiration releases energy while photosynthesis takes in energy.
Explanation:
- In the equation of cellular respiration , we can see that glucose and oxygen are utilized in the mitochondrion to produce carbon dioxide , water and chemical energy in the form of ATP.
- Glucose breaks down during cellular respiration .
- Again if we look at the chemical equation for photosynthesis in the chloroplast, we find that Carbon dioxide,which was produced during respiration is utilized along with water in presence of light energy to give out oxygen and Sugar (glucose)
The answer is programmed cell death
If a scientist wanted to compare the expression of one gene under two sets of conditions, chain termination is the technique they would use.
Chain termination is any chemical response that ceases the formation of reactive intermediates in a sequence propagation step withinside the route of a polymerization, efficaciously bringing it to a halt.
Sanger sequencing, additionally referred to as the “chain termination technique”, is a way for figuring out the nucleotide collection of DNA. The approach become evolved with the aid of using time Nobel Laureate Frederick Sanger and his colleagues in 1977, subsequently the call the Sanger Sequence.
