1. An animal cell has a 2% salt concentration. It is placed into a solution with a 0.05% salt concentration. What would happen t
jenyasd209 [6]

Answer: water will move out of the animal cell causing it to swell and burst  (Option C)


Explanation:


When a cell is immersed into a salty solution, the osmotic pressure generated by concentration differences of salt, will make the salt come in due to cell self-protection mechanism of the cell and water will come out, eventually the cell can burst .But since the animal cells has a higher concentration of salt and the solution has a lower concentration osmosis will take place and salt will move from higher salt concentration to lower.

Technological advances had helped reveal that the ocean floor was not flat, as once believed, but instead was marked by 50,000-k
poizon [28]
<span>By the late 1960s, scientists had developed the theory of plate tectonics based on a range of new evidence. Technological advances had helped reveal that the ocean floor was not essentially flat, as once assumed, but instead was marked by 50,000-kilometer-long (31,000-mile), 3,000-meter-high (9,800-ft) ridges and 11-kilometer-deep (7-mile) trenches. Scientists found striking patterns related to these features. They found that the youngest oceanic crust is located nearest the mid-ocean ridge and the oldest crust is nearest the trenches. They also detected a pattern of alternating magnetic polarity along the ocean floor, which emanated from the ridge tops. These two pieces of evidence, coupled with the fact that volcanic activity and island-building occurred most commonly at ocean trenches, suggested that new crust was created at mid-ocean ridges and destroyed at ocean trenches. Scientists Harry Hess and Robert Dietz used this evidence to revive and expand Holmes' convection theory into the theory they called "seafloor spreading." Finally, Wegener's notion of continental drift was coupled with a mechanism that could explain the movement of tectonic plates.</span>
