Plant absorb nitrogen gas from bacteria in the soil
No generations or hybrid would form before meselson and stahl would have observed evidence of a band in the cscl gradient.
The conservative model predicts that, following a single replication, half of the newly formed DNA double helices will be made entirely of the original, or old, DNA, and the other half will be entirely new. Then, each double helix would be completely replicated during the second round of replication. After that, 25% of the double helices would be all new, and 25% would be entirely old. Thus, the fraction of entirely new DNA double helices would increase with each succeeding round of replication, but the total number of completely unique DNA double helices would remain constant. Therefore, no hybrid DNA molecule containing 14N and 15N is replicated in the conservative model.

Ground my dude! wanna know how I know! I checked the other answers on the other one :)

Answer:
Stabilizing selection
Explanation:
The process of natural selection selects a species in one of the three ways: stabilizing selection, directional selection and disruptive selection.
During the process of stabilizing selection, nature does not favour the extreme phenotypes of the population but the intermediate phenotype with the maximum number of population.
In the given question, the Robin laid four eggs, neither more than four nor less than four which could have more disadvantages than the advantages. Since the intermediate number of eggs is favoured by nature therefore the stabilizing pattern is observed.
Thus, Stabilizing selection is correct.
