Answer:
Jawless fish was present before vertebrates.
Explanation:
Jawless fish has some characteristics of vertebrates and also considered as the ancestor of vertebrates on earth which is similar in appearance with the hagfish. It was present about 500 to 600 million years ago. They consist of cranium but vertebral column is absent. but with the passage of time, evolution occurs and many animals which was the descendant of this jawless fish having vertebral column or backbone in their body.
<h2>Replication </h2>
Explanation:
Meselson and Stahl began the experiment by growing E. coli in medium, or nutrient broth, containing a "heavy" isotope of nitrogen
When grown on medium containing heavy nitrogen the bacteria took up the nitrogen and used it to synthesize new biological molecules including DNA
After many generations growing in the heavy nitrogen, the nitrogenous bases of the bacteria's DNA were all labeled with heavy nitrogen and then the bacteria were switched to bacteria containing a light nitrogen and allowed to grow for several generations
They then measured the density of the DNA using density gradient centrifugation
Results obtained contained heavy DNA,Light DNA and hybrid of Light and heavy DNA
The experiment done by Meselson and Stahl demonstrated that DNA replicated semi-conservatively, meaning that each strand in a DNA molecule serves as a template for synthesis of a new, complementary strand
Had it been conservative mode of replication, DNA replication would have resulted in one molecule consisting of both original DNA strands (identical to the original DNA molecule) and another molecule consisting of two new strands (with exactly the same sequences as the original molecule)
Answer:
Diabetes is the condition in which the body does not properly process food for use as energy. Most of the food we eat is turned into glucose, or sugar, for our bodies to use for energy. The pancreas, an organ that lies near the stomach, makes a hormone called insulin to help glucose get into the cells of our bodies.
