Explanation:
1. Human and apes are evolutionarily closely related based on the analysis of their DNA sequences.
2. Wings of bats and birds serve the same function and are analogous structure.
3. Comparative anatomy is the study of the similarities and differences in structures in similar species.
4. Fossils demonstrate that during the evolution of the whale, the whale moved from land to the sea.
5. The human tailbone and appendix are vestigial organs.
6. The homologous structures are structures that are similar in related organisms because they were inherited from the common ancestor.
7. Comparative embryology is the study of similarities and differences in the embryo of different species.
8. The forelimb of all the mammals has basic bone structure.
9. Scientists who find and study fossils are called paleontologists.
Reflex action in the diagram would be the response. Diagram extracted from online.
<span>The Correct answer is not shown. The correct answer would have to say Atom A has one proton than Atom B because in the question it says Atom A has an atomic number of 19 and Atom B has an atomic number of 20.</span>
The carbohydrates found in our genetic material are the two sugars deoxyribose and ribose.
Carbohydrates are defined as organic compounds which occur in food and living tissue and include starch, sugars and cellulose. They are composed of hydrogen, oxygen and carbon.
Deoxyribose is a sugar found in the structure of DNA, while the sugar ribose is found in the structure of RNA.
DNA is the molecule that carries the cell's genetic information while RNA is the molecule involved in synthesis of protein using the coded information received from DNA.
Both DNA and RNA are termed as the genetic molecules of life.
