Answer:
Approximately 20,500 genes
Explanation:
The Human Genome Project (HGP) was a 13-year international research effort aimed at determining the entire DNA sequence of the human genome. The HGP was launched in 1990 and completed in April 2013. This project helped to identify and physically map all the genes of the human genome. The sequence obtained from the HGP has been a very useful point of reference in order to identify and characterize mutations associated with genetic disorders. The HGP predicted approximately 20,500 genes (each of them produces an average of three proteins), which are distributed in the 23 pairs of chromosomes in the cells of our body.
Answer:
Some islands have older islands at one end of the chain and younger islands at the other end. Example is the Hawaiian Islands.
Explanation:
Volcanic mountains or islands are formed when the tectonic plates in the earth’s crust converges. The string of Hawaiian volcanic islands were formed as a result of the movement of the Pacific plate over a fixed hotspot, where the magma rises upward and erupts on the seafloor. The northwestern islands are older than the islands to the southeast side of the Hawaiian islands.
The age of a volcanic rock is calculated by measuring the amount of argon and the amount of radioactive potassium present in the rock. These measurements are the supporting evidence which showed that the southeastern end of the chain is younger than the northwestern part of the chain. The volcanic islands gradually subside and erode as they age, so the older islands have much lower elevations than the newer islands. This is another evidence which supports the conclusion.
Fracking process is dangerous and hazardous for all our environment and its organisms.
<h3>What is your opinion about fracking?</h3>
Hydraulic fracturing is a type of oil and gas drilling that occurs across the country. Due to no safety regulations, it can polluted groundwater, pollute surface water, and harm wildlife.
So we can conclude that fracking process is dangerous and hazardous for all our environment and its organisms.
