Answer:
True.
Explanation:
This is true because Meteorites originate range from 4.5 billion years old to 200 million years old.
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:
Ionic compounds are ion compounds. These ions are atoms that gain or lose electrons, resulting in a net positive or negative charge. Metals tend to lose electrons, so they have a net positive charge and become cations. Non-metals tend to gain electrons, creating a net negative charge of anions.
Explanation:
D) Gases such as carbon dioxide and methane
And the more of these from gas emissions, etc. then the more global warming.
FYI: ozone helps to blocks cosmic gamma rays from reaching earth
False, It will basically be a carbon sink. Taking in more than it produces.
