The atomic number of an element is the number of protons in the nucleus of an atom of that element.
Atoms with the same number of protons, but a different number of neutrons are called isotopes.
The genealogy tree which is missing from the question is in the attachment.
Answer: 1) P1 = 
; 2) P2 = ; 3)P3 = 
Explanation: 1) According to the genealogy tree, the individual III-3 has a P1 = 1/2, because each of the parents are heterozygous for the condition, since one of the ofspring is affected.
2) For individual III-4, one of the parents is heterozygous for the condition, so the probability of being a carrier is P2 = 1/2.
3) Now, for individual IV-1 be affected, the parents has to be carrier. So, this probability, depends on the probability of each parent being heterozygous and that the individual will be carrying the condition, which means:
P3 = 1/2 · 1/2 · 1/4 = 1/16.
The probability of having the condition is 1/16 or 6.25%.

Most of the increase in global temperatures since 1950 has been caused by human activity.
The United States is the second largest contributor to carbon dioxide (CO2) in our atmosphere
As global temperatures increase, our societies will find it harder to adapt to the changes this brings, and some species are more likely to go extinct
The concentration of carbon dioxide (CO2) in our atmosphere, as of May 2020, is the highest it has been in human history.
NASA data show that average global temperatures in 2019 were 1.8 degrees F (0.98 degrees C) warmer than the 20th century average. In fact, the five warmest years in the 1880–2019 record have all occurred since 2015
Global warming puts coral reefs in danger as the ocean warms, scientist fear that coral reefs will not be able to adapt quickly enough to the resulting changing conditions, and bleaching incidents and diseases will increase
