Answer:
I believe your answer is correct
Explanation:
.
Answer:
c. minimal media with leucine and streptomycin
Explanation:
Although F- Strain of bacteria require very minimal media due to the rate of their fertility factor but the minimal media must include at least one amino like leucine and antibiotic like streptomycin because these both are necessary for the proper replication process and indeed for the proper growth.
Answer:
Evidences of evolution are categorized as follows -
- Direct observation of evolutionary change
- Homology and development
- Fossil record and biogeograhy
- Vestigeal organs
Explanation:
Evolutionary changes can be observed either in nature or at a small scale in laboratory by the conditions experimentally generated. For example we can take an organism which has small life span like <em>Drosophila</em> and artificially produce earliest environment like conditions to observe how its development is affected.
Homology supports the common ancestry of the organisms. Homologous structures are formed from a common ancestor. Even if these are structurally different, developmentally they are related.
Fossil records are the most important evidences that document changes in the organisms in the course of time. Sedimentary rocks are the most rich sources of fossils.
Some structural or genetic features serve no apparent purposes. These are called vestigial organs. But as these are present in the organism they show that these are functional in the early forms of that organism.
Farm laborers would have been affected by the outbreak of mastitis by receiving a smaller amount of salary. The farm owners would face a problem in the disease cost. Consumers of the dairy product would receive a low-quality dairy product with a higher price because the mastitis makes a degradation in dairy product quality.
:<span> </span><span>Fossils show how older fossils are different than modern animals. Since they are often able to be precisely dated they prove that all organisms changed over time. It isn't like there is an actual scientific controversy about it. They clearly show organisms radiating into to new types of animals and they undeniably prove evolution beyond any rational doubt. DNA evidence is probably even better and it completely supports the basic assumptions though there have been a few surprises since the fossil record isn't entirely complete. </span>
