I'm just learning how to speak Spanish, so what does this say?
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>
The analyst
is determining the direction of the public opinion. By understanding the direction
of the public opinion, an analyst will find which position does the majority of
people hold into. The direction could be a positive or a negative direction.
Maybe it’s Asia? (sorry if it’s not correct)
Answer:
Under normal circumstances, bronchoconstriction is caused by Parasympathetic nervous system and bronchodilation is caused by sympathetic nervous system
Explanation:
bronchoconstriction is simply a a tightening, narrowing or constriction of the of brochioles ( airlways) that increase in mucous secretion and it may occour due to coughing, sneezing or any other factors.while bronchodilaiton is the relaxation or the dilation of the bronchioles (airways in the lungs) that decrease of mucous secretion
An increase in parasympathetic activity causes BRONCHOCONSTRICTION, a decrease in parasympathetic activity causes BRONCHODILATION. There is no sympathetic innervation of the bronchiole smooth muscle!
The effect of the Smooth muscle contraction usually may cause bronchoconstriction to decline or decrease in the diameter of the bronchioles while the effect or the result of the smooth muscle relaxation may cause bronchodilation to increase in the diameter of the bronchioles. Therefore, Parasympathetic stimulation leads to bronchoconstriction and sympathetic stimulation leads to bronchodilation.
