Answer:
In diffusion, particles move from an area of higher concentration to one of lower concentration until equilibrium is reached. In osmosis, a semipermeable membrane is present, so only the solvent molecules are free to move to equalize concentration.
Explanation:
Answer:
The easiest way to differentiate them is to remember that the site of an area is its exact location and the situation describes its surrounding areas and physical features. Favorable features of site and situation will ensure that the city will be able to thrive and survive.
Answers and Explanations:
1. Secant line
There are various different kinds of lines in geometry, and each has its own aspects. A secant line is a line that crosses the shape or graph at exactly two points. Here, we can see that line BC crosses circle A at two points: B and C, so we know it's a secant line.
2. Chord
A line segment that connects two points on a circle without crossing the center is called a chord. Now, if the segment <em>had</em> crossed the center, then it would have been called the diameter.
3. Tangent line
As aforementioned, there are different kinds of lines in geometry. Where a secant line has two intersection points, a tangent has only one. Tangent literally means "touching", and we can see from the picture that the line running through point B is "touching" circle A at exactly one point: B.
