The quantized model for electron orbits in atoms that effectively explained the spectroscopic behavior of the atoms. Each line in the spectrum corresponds to one exact frequency of light emitted by the atom.
Answer:
This is due to the event of Speciation that happened for the rodents in Island B but not for the rodents in Island C.
Explanation:
- Due to splitting of the population,
- The sub-population of rodents formed in Island B are B1 and B2.
- The sub-population of rodents formed in Island C are C1 and C2.
- In case of Island B, each of the B1 and B2 sub-populations that got split from each other developed certain mutations that were necessary for them to adapt to the particular diverse environment each of them were exposed to, through the period of 50,000 years. These mutations were so varied that reproductive isolation was generated between them that resulted in each of them to develop into different species.Hence, speciation happens here and B1 and B2 are incapable of inter-breeding.
- In case of Island C, each of the C1 and C2 sub-populations that got split might have got exposed to similar environmental change or no environmental change or the environmental change might have been too small to cause drastic change in each of the sub-populations. As a result of this the two sub-populations might have acquired certain mutations to adapt to the environment each of them were exposed to, through a period of 100,000 years. These mutations might not have been too variable or contrasting to cause reproductive isolation between C1 and C2. Hence, no new speciation happens here and C1 and C2 are capable of inter-breeding.
Answer:
The answer is C
Explanation: The random change in the gene pool is due to genetic drift. Remember, genetic drift occurs at a more rapid rate when the population size is reduced. The flood is a random occurrence. It could have as easily been a drought.
Answer:
The following might explain the lack of cloud formation
- The air package never reaches its dew point.
- There are too few aerosols present in the air package.
<u>Explanation</u>:
For the formation of the cloud the air in the higher position should have much colder than that of the surface. The vapours travels till it reaches the point where it has lower temperature as well as the pressure so that the water will condense into the droplets which will result in the formation of the cloud. When those vapours condenses to the liquid or to the solid it will release some of it energy to the air. For the formation of the cloud three things are mandatory and they are moisture, cooling air and the condensation nuclei. Also, for the formation of clouds, suspended particles like aerosols are required for the water to condense. As there are few aerosols, water doesn't get to condense.
