Explanation:

Europe and Asia. The boundary between Europe and Asia is unusual among continental boundaries because of its largely mountain-and-river-based characteristics north and east of the Black Sea. The reason is historical, the division of Europe and Asia going back to the early Greek geographers. Europe is considered a separate continent from Asia because of its distinct historical, cultural and political identity, rather than any clear geographical demarcation. ... A large part of Turkey lies in Asia, however, culturally and politically, it has been closer to Europe and therefore sees itself as a European country

If an animal cell is placed in plain water, It will swell and burst. The bursting of the cell is a result of which biological pr

densk [106]

Answer:

Osmosis is the process of having water pass from a low concentration medium to a high concentration one, given that the barrier (membrane) is semi-permeable.

Explanation

Cells encounter osmosis due to their semi-permeable membranes. Water can flow past cell membranes. A given cell placed into distilled water will have some water flow into it, causing it to burst. A given cell placed in a very concentrated water will have some water flow out of it, causing it to shrivel. A given cell placed in a solution with the same concentration of minerals as the cell will have an equilibrium of water flowing in and out. This is the case of IV (Intravenous therapy) when we want to deliver substances into a human blood. We want to make sure the liquid delivered is as concentrated as the blood to avoid cell shriveling or bursting.

This picture above sums up the 3 cases cells could face in a solution.

Good luck!

During a marathon race, a runner's blood flow increases to 10.0 times her resting rate. Her blood's viscosity has dropped to 85.

Ksenya-84 [330]

Answer:

1.543

Explanation:

According to Poiseuille's law, blood flow (Q) is given by:

$Q= \frac{\pi *\Delta P*r^4}{8*\mu*L}$

Where ΔP is the blood pressure difference, μ is the blood viscosity, r is the radius of the blood vessel, and L is the length of the vessel.

During a marathon, the new radii of her blood vessels (r') are

$10*Q= \frac{\pi *1.5\Delta P*(k*r)^4}{8*0.85\mu*L}\\5.667*Q= \frac{\pi *\Delta P*(k*r)^4}{8*\mu*L}\\k^4=5.667\\k=1.543$

The average radii of her blood vessels increased by a factor of 1.543

Which substances form covalent bonds?

faltersainse [42]

Answer:they usually occur between nonmetals. For example, in water each hydrogen and oxygen share a pair of electrons to make a molecule of two hydrogen atoms single bonded to a single oxygen atom. In general ionic bonds occur between elements that are far apart on the periodic table.
