Answer: high-pressure system
Explanation:
Energy is lost at each Trophic level of a food chain. The more levels then the more energy lost to those at the top.
Question is incomplete. Complete question is as follows:
A researcher was studying mutations in bacteria. He found that certain bacteria had changes in their DNA that allowed them to be resistant to antibiotics. This research is an example of 1._______The mutation will lead to 2.________.
1.
A.Embryology
B. Evolution Genetics
C.Comparative Anatomy
2.
A. All the bacteria becoming resistant to the specific Antibiotics
B. The Bacteria becoming nonresistant to specific Antibiotics
C. Less Bacteria becoming resistant to the specific Antibiotics
Answer:
1. B. Evolution Genetics
2.C. Less Bacteria becoming resistant to the specific Antibiotics
Explanation:
Evolution genetics is the field in which evolutionary changes in genome are studied. Here, the bacterial population was exposed to the antibiotic. In response, some bacteria showed mutations in their genome which made them resistant to the antibiotic. Since the genetic composition of bacteria has changed and made them to evolve, it would be a part of evolution genetics.
The fewer bacteria which showed these mutations became resistant to that particular antibiotic. However, this does not mean that the entire population will become resistant to the antibiotic. It is going to take a long time.
