Answer:
B. The hurricane has caused a population bottleneck
Explanation:
When there is a sudden reduction in the size of a population due to some unfavorable environmental conditions, the population is said to have experienced bottleneck. Bottleneck mostly results in genetic drift and changes the allele frequencies in the population. It is caused by some natural disasters or adverse conditions such as a hurricane.
In the given example, the hurricane removed all the birds with green feathers from the population and also has reduced the population size from 1000 to 10. Therefore, it represents the population bottleneck.
Yes, C4 is a process used by plants to survive in hot dry climates along with the CAM cycle. Hope this helps!
The Universe is defined to be the sum total of everything that we know about: stars, galaxies, clusters, superclusters, voids, etc.
Cosmology is the study of the structure and evolution of the Universe.
It is a subject of great current interest, as the Hubble Space Telescope and other new instruments have recently helped astronomers shed light on many important questions.
There have been many theories about the Universe, but they generally all share one fundamental postulate, the cosmological principle, which has two parts. First, the Universe must be isotropic (the same in every direction).
For example, the Hubble deep field images, extending 12 Gly away, for two completely different directions, are remarkably similar:
