The sample that is being discussed in the problem can be either DNA or RNA.
DNA and RNA are both very important molecules. Both of these hold immense value in biology since they store all the vital information required for living. The basic structures of the two are quite similar; the only difference is that DNA is double-stranded while RNA has a single strand.
DNA and RNA molecules both contain a five-carbon sugar (ribose), a phosphate group, and a nitrogenous base. Except for cytosine, guanine, and adenine, the fourth part is the phosphate group that exists in both. RNA has Uracil while DNA has Thymine.
Since it has not been mentioned here what the fourth part might be, the sample might be a DNA or an RNA molecule.

Answer:
Because the element carbon forms the backbone of the molecules that make up cells, one of the most important biogeochemical cycles to life on Earth is the carbon cycle. ... Carbon moves from living things back to the environment as all types of organisms use some of their food molecules as a source of energy.
Explanation:
The correct answer is option C, that is, mammals were able to diversify to make use of the variety of habitats that were previously occupied by dinosaurs.
Adaptive radiation refers to the comparatively fast evolution of various species from a single common ancestor. Adaptive radiation usually takes place when a species enters a novel area and distinct traits influence its existence. An illustration of adaptive radiation is the progression of mammals after the annihilation of dinosaurs.
Answer:
a). Major products of glycolysis include pyruvate, ATP , and NADH
b) Glycolysis is the process by which glucose is converted to two molecules of pyruvate.
Explanation:
Glycolysis is a process in which a glucose molecule is broken down into two molecules of pyruvate. The process of glycolysis occurs without oxygen therefore it can occur in both aerobes and anaerobes.
The process of glycolysis occurs in the cytoplasm of the cell and the products of glycolysis are 2 molecules of pyruvate, 2ATP, and 2 NADH molecule. Then the pyruvate molecule gets into mitochondria which it's complete oxidation takes place. Therefore the right answer is a and b.
