Explanation:
Wind energy is one of the sources of renewable sources of energy that is environmentally friendly.
It uses wind power to generate other forms of energy mostly electricity.
Some of the drawbacks are:
- Wind turbines pose serious threat to wildlife. It is common place to see dead birds in areas where wind power is being harnessed.
- The quantity fluctuates from time to time. Since wind is an element of weather, it is not always in regular supply as desired.
- The cost of constructing wind turbines can be very high a times.

<h2>Scientist Observing changes </h2>
If the population of the species is significantly decreasing then the species could become extinct. The decline in population is due to some factors like less immigration, aging, and decreasing fertility rates. But the most is due to less immigration which causes to decrease population. The extinction of population can be prevented by some serious actions which should be taken government.
The correct answer is A. Two populations of finches that cannot produce viable offspring
Explanation:
Reproductive isolation is a biological and evolutionary phenomenon that prevents two species from successfully reproducing, this means they cannot produce offspring or the offspring is not fertile, even if these species had a common ancestor. Additionally, as a result of reproductive isolation, each species keeps its genes and features. This phenomenon is best exemplified in "Two populations of finches that cannot produce viable offspring " because this refer to the barriers for different species to reproduce or produce viable offspring, which is the focus of reproductive isolation.
Answer:
Answer B. Endosymbiosis
Explanation:
Early protists were first eukaryotic organisms and had several membrane bound organelles. The anaerobic protists evolved by acquiring purple bacteria. The purple bacteria have the ability to carry out aerobic cellular respiration. The endosymbiont transformed into mitochondria in due course of evolution. Similarly, the photosynthesizing protists were evolved by endosymbiosis of cyanobacteria which in turn was transformed into chloroplast during further evolution.
