Answer:

A circuit with two 10 ohm resistors connected in series.

Explanation:

The formula for the equivalent resistance for resistors in parallel is

\frac{1}{Rt} = \frac{1}{R1} + \frac{1}{R2}   So if R1=R2= 10  \frac{1}{Rt} = \frac{1}{10} + \frac{1}{10} = \frac{2}{10}   Rt =\frac{10}{2} =5 ohm

The formula for the equivalent resistance for resistors in series is

Rt = R1 + R2  So Rt= 10 + 10 = 20

Explain what an exoskeleton is and what it is made of.
sergey [27]
The bodies of arthropods are supported, not by internal bones, but by a hardened exoskeleton<span> made of </span>chitin<span>, a substance produced by many non-arthropods as well. In arthropods, the nonliving exoskeleton is like a form-fitting suit of armor. It is produced by the "skin" and then hardens into a protective outer-covering.</span>
