As the earth has active tectonics we know that rocks are recycled and the oldest rocks may therefore just be the oldest rocks that have not been recycled yet. We know the true age of the earth by looking at radioactive isotopes of things like spacedust and meteors that formed at the same time as the earth as they have not been affected by the tectonic process of recycling here on Earth.
Answer:
Option 1, No. The highest frequency of heterozygotes under Hardy-Weinberg equilibrium is 0.5
Explanation:
As per Hardy Weinberg’s equilibrium principle, the maximum frequency of heterozytotic individuals occur only when half of the population is dominant and recessive homozygous.
In other way when the sum of frequency of dominant and recessive species is equal to 0.5, only then the frequency of heterozygotes is maximum which in any case would not be higher than 0.5.
Hence, option 1 is correct
In short, air pollution is foul air injurious to health. Air Pollution is anything that goes into the air that is harmful.Most air pollution is man-made. The largest contributor to airpollution is the burning of fossil fuels such as gas and coal. Someof the most common forms of air pollution are: Particulate matterNitrogen oxide (and other oxides of nitrogen) Sulfur oxide AcidRain VOC's (volatile organic compounds) Air pollution can also besaid as the accumulation in the atmosphere of substances that insufficient concentrations, endanger human health or produce othermeasured effects on living matter and other materials. Among themajor sources of pollution are power and heat generation, theburning of solid wastes, industrial processes, and, especially,transportation.
