The mass of a tree is primarily carbon. The carbon comes from carbon dioxide used during photosynthesis. During photosynthesis, plants convert the sun's energy into chemical energy which is captured within the bonds of carbon molecules built from atmospheric carbon dioxide and water.
1. Structure such as the human tailbone or appendix that evolution has reduced in size because it is no longer used = d. vestigial structure
2. study of the similarities and differences in the structures of different species:
= g. comparative anatomy
3. structure that is similar in related organisms because it was inherited from a common ancestor: = c. homologous structure
4. study of the similarities and differences in the embryos of different species: study of the similarities and differences in the embryos of different species = j. comparative embryology
5. scientist who finds and studies fossils to learn about evolution and understand the past:
= i. paleontologist
6. mistaken idea of jean baptiste lamarck that evolution occurs through the inheritance of traits that an organism develops in its own lifetime: = h. inheritance of acquired characteristics
7. process by which a single species evolves into many new species to fill available niches:
= e. adaptive radiation
8. relative ability of an organism to survive and produce fertile offspring: = k. fitness
9. structure that is similar in unrelated organisms because it evolved to do the same job, not because it was inherited from a common ancestor: = f. analogous structure
10. study of how and why plants and animals live where they do: = a. biogeography
11. process in which organisms evolve traits useful to humans because people select which individuals are allowed to reproduce and pass on their genes to successive generations:
= b. artificial selection
Answer:
This is because it is a selective antibiotic that, when entering the body, binds to the 50s subunit of bacterial ribosomes, thus causing the disruption of protein transcription of bacteria.
This drug does not stop the transcription of human proteins since bacteria and humans do not have the same ribosomes, therefore, humans or sick cells do not have the active site to which the drug binds.
Explanation:
This is because it is a selective antibiotic that, when entering the body, binds to the 50s subunit of bacterial ribosomes, thus causing the disruption of protein transcription of bacteria.
This drug does not stop the transcription of human proteins since bacteria and humans do not have the same ribosomes, therefore humans or host cells do not have the active site to which the drug binds.
Erythromycin falls into the macrolide family and is considered a drug that is bacteriostatic at low concentrations and bactericidal at very high concentrations.
The difference between these named terms is that one ends the life of the bacterium (bactericidal) and the other stops the bacterial metabolism preventing its possibility of increasing in number.
Tracheotomy refers to creating an opening in the neck in order to place a tube into a person's windpipe.
