B The idea of evolution did not develop until natural phenomena described what was occurring.

. Evolution is most likely to occur when populations are subjected to strong pressures. The addition of antibiotics to a bacterias environment causes mutations in the bacterias genes that make them resistant to death by the antibiotic chemical. Evolutionary origin of bacteria and viruses Earth formed between 45 and 6 billion years ago.

What is the result of double fertilization in an angiosperm. The biological species concept b. Which of the following statements describes the evolution by natural selection of mycobacterium tuberculosis bacteria in their new environment The drug-resistance trait is an adaptation to the environment in which human hosts are medicated with the antibiotic rifampin.

Which of the following best describes the evolution of bacteria. Biological evolution is best described as. The biological species concept.

C The hard parts of animals that are rich in. Random assortment of genes results in better. Currently occurring only in scientific laboratories c.

3Cell communication evolved early in the history of life because cell. Nucleotide exchange insertion and deletion are the most frequent events. A The theory of evolution describes a body of observations about the changes in organisms.

Bacteria inject DNA into other cells with the help of a tube this process is called Conjugation. Which statement best describes the appearance of these resistant varieties. Bacteria are single-celled microorganisms with the absence of the nucleus and other c ell organelles.

Sympatric speciation The correct answer is. 2Cell communication does not occur in bacteria suggesting it evolved after the emergence of multicellular organisms. An individual bacteria can get a new mutation during its lifetime that will allow it to suddenly become resistant.

Today certain varieties of this bacterium are resistant to penicillin. They are also very versatile organisms surviving in extremely inhospitable conditions. The bacteriophage is a virus that replicates within the bacterial cell.

Darwin proposed that evolution could be explained by the differential survival of organisms following their naturally occurring variationa process he termed natural selection According to this view the offspring of organisms differ from one another and from their parents in ways that are heritablethat is they can pass on the differences genetically to their own offspring. Postzygotic isolation mechanisms e. An inevitable consequence of the nature of organisms Which describes natural selection.

Hence they are classified as prokaryotic organisms. Endosymbiotic theory describes the evolution of mitochondria and chloroplastAccording to itphotosynthetic bacteria and aerobic bacteria engulfed by a eukaryotic cell turned into chloroplast and. Well you see the evolution by natural selection of Mycobacterium teberculosis bacteria in their new environment is described best with one word.

By about 30 billion years ago however an atmosphere that contained the appropriate blend of nitrogen oxygen carbon and hydrogen allowed life to commence. Which best describes how resistant to antibiotics will aid in the evolution and survival of bacteria. The presence of the antibiotics reduces competition between the bacteria present which will allow some.

Bacteria transfer DNA with bacteriophages is called transduction. Up to 10 cash back In vitro and in vivo experiments with antibiotic-resistant bacteria have shown that bacterial evolution in the absence of antibiotics is more likely to result in compensatory mutations improving the fitness of antibiotic-resistant bacteria rather than in reversion to highly fit antibiotic-sensitive bacteria Levin et al. Scientists think that horizontal transfer also occurred frequently during the early evolution of life and explains why so many distantly related bacterial lineages can photosynthesize.

Evolution is best described as A change over time B improvement over time. Bacteria change from lysogenic to lytic is called induction. The evolutionary species concept.

The structure of bacteria is known for its simple body design. The evolutionary species concept. Constantly occurring at the same rate in ALL organisms d.

Mutualism is the type of association between two organisms in which both parties benefit from one another. Which of the following best describes how antibiotic resistance in bacteria can evolve. Answer choices bacteria resistant to the antibiotics will survive reproduce and pass on their resistance to the next generation.

A rare event b. Conditions initially remained inhospitable for the potential development of life. Some live and some die in each generation b.

Describes the evolution of cell communication in organisms. The genes coding for these processes were passed directly from lineage to lineage and when the genes were successfully picked up incorporated into a lineages genome and deployed that lineage. 0 The shape of the teeth became more pointed Which sequence of events best describes the current theory of the origin of life on Earth.

Thus Option A is correct. The size of the brain cavity increased. Question Correct Mark 250 out of 250 Which of the following best describes the evolution of bacteria.

C Darwins original theory of evolution was modified to the current theory as. An example of mutualism is the relationship between bacteria and leguminous plants. Prezygotic isolation mechanisms c.

See answer 1 Best Answer. In addition module exchange between different genes gene disruptions and deletions occur at. The evolutionary species concept d.

It was very effective in destroying the bacteria that cause gonorrhea. Which best describes how resistance to antibiotics will aid in the evolution and survival of bacteria. The size of the skull decreased.

Bacteria resistant to antibiotics will survive reproduce and pass on their resistance to the next generation. 1Because single-celled organisms do not use cell communication to survive it most likely evolved after multicellular organisms. Bacterial evolution requires the modification of old functions and the development of new ones.

The relationship between bacteria and legumes that results in nitrogen is best described as mutualistic. Only the largest and strongest survive c. Leguminous plants provide shelter for.

Mutation rates in bacteria are generally in the range of 10 6 to 10 9 per nucleotide per generation. 0 The shape of the head became flatter.
