The correct answer is A. A burst of speciation
Explanation:
Adaptative radiation is part of evolution and occurs when a single organism or species diversify into a wide range of species (speciation), this process is called "adaptative" because the speciation occurs due to changes in the environment that make challenging survival usually due to the reduction of resources available and therefore organisms change to adapt to new conditions. Additionally, in adaptive radiation, the new organisms share traits with their common ancestor but also have different and unique traits. Considering this, it can be concluded adaptative radiation a burst of speciation.
The answer is c. Hope this helps
Answer:
The relative frequency of the mutation will increase as time passes.
Explanation:
This random mutation has, by chance, caused a phenotype that is beneficial to the bacteria. This mutation improves the fitness of the bacteria, as they are able to utilize more food sources. This reduces the chance of starvation and death of the cell. Therefore, cells with this mutation are more likely to survive, and for longer.
In times where nutrients are scarce, bacteria without the population will die off. But the bacteria with this mutation will be more likely to survive and pass on their genetic material. Therefore, over time, the frequency of this mutation will increase.
