Why do only Microbats use echolocation? Are they different in:
-Intelligence?
-Size?
-Prey?
-Biology?
-Anatomy?
-Habitat?

Anything that'll answer why only microbats use echolocation and how they are different is helpful!

If a person was exposed to radiation 20 years ago, does it wear off gradually over time, or does the amount stay the same in your system over the years. Thank you.

If salt crystals are put in water, the saturation point is said to be 26%, when crystals are still visible at the bottom. I assume that means sitting still. If I use red (Himalayan) salt, I can see that when I shake the container, more particles of salt float around, and cloud it. This water must be a higher % than the still water. I know it's just guess work, but what would you say is the salt % in the shaken water.

Answer any or all you can (please specify the number), and I always pick a best answer...

2. The graph of a quardatic function can have 0, 1, or 2 x-intercepts. How can you predict the number of x-intercepts withoug drawing the graph or (completly) solving the problem?

3. Discuss two ways to complete the square.

4. Explain why it is necessary to check all solutions in a rational equation.

5. Explain why |x| < p has no solution for p (less than or equal to) 0.


Thank you so much, and, remember to specify the answer!
