What changes were most likely caused by a shift in earth's continents?
Blizzard [7]

Answer:

The earth’s crust is broken into separate pieces called tectonic plates (Fig. 7.14). Recall that the crust is the solid, rocky, outer shell of the planet. It is composed of two distinctly different types of material: the less-dense continental crust and the more-dense oceanic crust. Both types of crust rest atop solid, upper mantle material. The upper mantle, in turn, floats on a denser layer of lower mantle that is much like thick molten tar.

Each tectonic plate is free-floating and can move independently. Earthquakes and volcanoes are the direct result of the movement of tectonic plates at fault lines. The term fault is used to describe the boundary between tectonic plates. Most of the earthquakes and volcanoes around the Pacific ocean basin—a pattern known as the “ring of fire”—are due to the movement of tectonic plates in this region. Other observable results of short-term plate movement include the gradual widening of the Great Rift lakes in eastern Africa and the rising of the Himalayan Mountain range. The motion of plates can be described in four general patterns:

Collision: when two continental plates are shoved together

Subduction: when one plate plunges beneath another (Fig. 7.15)

Spreading: when two plates are pushed apart (Fig. 7.15)

Transform faulting: when two plates slide past each othe

A student performed an experiment with bags of dialysis tubing filled with distilled water to model the process of osmosis. Dial
Reil [10]

Answer:

Taking into account the principle of osmosis, the question that best addresses experimental design is  <em>How does the effect of environmental sucrose concentrations impact the  movement of water across a membrane?</em>

Explanation:

The experimental design of the student, made with dialysis bags and sucrose at different concentrations should recreate the principle of osmosis, of importance in living beings for organic homeostasis.

Osmosis consists of the movement of water - through a semi-permeable membrane - from a less concentrated solution to a higher concentration solution, following a gradient, to achieve balance.  

The student will observe in his experiment that water moves from the solution with less sucrose concentration to the higher concentration of sugar. Beakers with the highest concentration of sucrose will have the highest weight, due to the increase in liquid volume.

How does the effect of environmental sucrose concentrations impact the  movement of water across a membrane?

The experiment shows that:

  1. The water from the beaker with less sucrose concentration moved -through the dialysis tubes and the membrane- to the beaker containing the most concentrated sucrose.
  2. Different sucrose concentrations will attract different amounts of water, which influences the final weight of each container.

With this experiment the principle of osmosis is confirmed, where the concentration of a solute determines the amount of water that passes through a semipermeable membrane -following a concentration gradient- until equilibrium is reached.
