The remains of a teenage girl, aged 15–17 at her death, and nicknamed <u>"Naia"</u>, <em><u>that are more than 12,000 years old</u></em>, were inside a flooded cave located near <em><u>Tulum, Quintana Roo in Mexico</u></em>. They were recovered in 2007 by the cavers Alejandro Álvarez, Alberto Nava and Franco Attolini, of the<em><u> Tulum Speleological Project (PET)</u></em>, dedicated to the registry of the underwater heritage of the region. After seven years of research, a multidisciplinary team from USA, Canada and Mexico, whose principal investigator of the research on <u>"Naia"</u>, <em><u>James Chatters</u></em>, an archaeologist and paleontologist, reported in 2014, that <u>"Naia</u>" has already contributed to understand the origins of the first Americans and her DNA <em><u>confirms the idea that "a single group of Asian emigrants gave rise to both the earliest American settlers and modern Native Americans"</u></em>. <u>So, right answer is B. Members from one single, genetically uniform population populated the Americas from at least 16,000 years ago.</u>

Answer:
AFFECTED FOR PLANT GROWTH
Studies have shown that higher concentrations of atmospheric carbon dioxide affect crops in two important ways: they boost crop yields by increasing the rate of photosynthesis, which spurs growth, and they reduce the amount of water crops lose through transpiration.
affected for nutrition level
AFFECTED FOR NUTRITION LEVEL
Climate change affects food production and availability, access, quality, utilization, and stability of food systems. In short, it impacts all aspects of the food system. Extreme weather-related disasters are increasing and reduce the yields of major crops. Higher levels of CO2 reduce the nutritional value of crops.
