True.
The earth is made of several subsystems or spheres that interact to form a complex and continuously changing (dynamic) state that is termed as the earth system.
Even though the earth system is a closed system, it self regulates through the subsystems such as the water cycle and carbon cycle.
The earth system is characterized by numerous overlapping cycles in which matter is recycled over and over again. Cycles involve multiple spheres and systems interactions. Humans impact and are impacted by the cycles in various ways.
Answer:
c. There will be a net diffusion of oxygen from the water into the bloodstream only if the partial pressure of oxygen in the water is greater than 100 mm Hg
Explanation:
Diffusion involves the movement of molecules from the region of higher concentration to the region of lower concentration. If the molecules are gas molecules, they will diffuse from the region of higher pressure to the region of lower pressure.
Hence, for net diffusion to occur from the water to the bloodstream, the partial pressure of oxygen in water must be higher than the partial pressure of oxygen in the bloodstream.
<em>Since the partial pressure of oxygen in the bloodstream is 100 mm Hg, then the partial pressure of the gas in water must be more than 100 mm Hg in order for net diffusion to occur from water to the bloodstream.</em>
Answer:
The Eocene Epoche coincides with the form of primates which are placental mammals.
Explanation:
The main characters of placental mammals contain large body,bigger brain that appear at that time from the fossil record.
True primates were evolve in 55 million years ago,at the beginning of eocene epoch.
These fossil records were found in North America, Europe, Asia.
The fossil were squirrel like size with grasping hand,feet, that helps them for climbling the tree.
The fossil record of primate that were found contain stereoscopic vision.
15 degrees Celsius is colder than 20 degrees Celsius. It gets colder as the temperature decreases.
Answer:
i think its increase in precipitation
