2. In series, we add the resistance up
Use the formula V = IR to find the current.
R = 10+4 = 14, V=42
42=I (14)
I = 42/14 = 3 A
3. Closed
4. Answer B
This is because unlike poles attract and like poles repel.

You can make an electromagnet stronger by doing things like wrapping the coil around a piece of iron adding more turns to the coil, increasing the current flowing through the coil.
Answer: 2; 3
For each FADH2 that supplies electrons to the electron transport system, 2ATPs are synthesized. For each NADH that supplies electrons to the electron transport system, 3 ATPs are synthesized.
Explanation:
Both FADH2 and NADH are you reducing equivalents in that they give off electron in terms of hydrogen atom or a hydride ion.
Thus, in the inner membrane of the mitochondria where electron transport occurs, FADH2 gives off its hydride ion yielding 2 ATP molecules; while NADH gives off its hydride ions to yield 3 ATP molecules
Short explanation:
It is true that all animals including humans share a common ancestor, so we're all related in a way. Turns out, some species are more similar to other since they shared a longer "common-evolutive path".
Comparison:
If we compare antelope and squirrels, we might see they don't have much in common. Antelopes are bigger, have a different diet, have a differnt habitat, have a different colour, have horns, etc. And all that also applies to squirrels.
If we compare rabbits and squirrels, we can see that the have a similar size, similar diet, alike teeth, a similar habitat in some occasions, etc.
Answer:
The most logical prediction would be that rabbits and squirrels have more similar DNA than antelope and squirrels.
