Answer:
The outer pleura is attached to the chest wall (1-9). The pleural cavity aids optimal functioning of the lugs during breathing. It transmits movements of the chest wall to the lungs, particularly during heavy breathing.
Answer;
mACB=32 degrees
Explanation;
If the measure of the arc is 64 and you are finding the measure of an inscribed angle (ACB) then you divide by two.
<ACB is an inscribed angle whose intercepted arc, AB, measures 64°. Since an inscribed angle is measured by 1/2 the measure of its intercepted arc, the measure of <ACB is (1/2)(64°) = 32°
I’m guessing Asia and North America to be closer
Answer:
Eukarya
Explanation:
According to the given information, the observed cells have nuclei and chloroplasts. The presence of a well-defined nucleus and other membrane-bound organelles such as chloroplasts is a feature of eukaryotic cells. All the eukaryotic organisms are assigned to the Domain Eukarya. Therefore, the observed cells belong to the domain Eukarya. Due to the presence of chloroplasts in them, these cells may belong to the kingdom Plantae of domain Eukarya. Domains Archaea and Bacteria include prokaryotic organisms.
The Precambrian time refers to the time 4.5 billion to 542 millions year ago. This period is characterized by having reduced atmosphere and included reduced compounds. Scientists believed that atmosphere at that time was devoid of free oxygen and CO2 was present in excess. Before the complex life evolved on the Earth, the Precambrian Earth's ocean contained dissolved carbon dioxide.
