Answer:
The phrase "disease is an agent of natural selection" means that those individuals which carry specific genes to resist the disease will be selected by the nature, whereas those individuals which that don't have or not capable of developing resistance genes will be excluded.
It is a well-established fact that diseases (mainly outbreaks) are best action of nature to select only those individuals which can modify there genetic material and thrive against the changing environmental conditions. Let's take the example of Coronavirus outbreak (COVID-19) this year. From the statistics we know that old people that develop the disease are most likely killed within a few days. However, young people can develop immunity against the virus easily. Hence, nature selects young people and exclude older people. This natural phenomenon is however driven by the disease.
The diploid is 30. The haploid is 15. Option C is most likely correct.
Answer:
Adding fertilizer makes the growth speed of a plant faster.
Independent: Fertilizer
Dependent: Growth of plant
Control: How much fertilizer
Explanation:
I think that's the answer. I hope this helps :)
Distance = speed x time
Distance = 20 x 24
Distance = 480 miles
The clouds will have travelled 480 miles.
The clouds will still have 700 - 480 = 220 miles before they reach the city. The weather will be dry.
Earth has a lower average temperature than the moon. Although, some might think that the earth has a higher average temperature because the earth is hot. Yet, the moon has far more avaerage temperature than the earth because the earths atmosphere blocks the suns radiation from directly hiting it. Also, the moon doesn't have a atmosphere to keep away the suns radiation.
