Negative degrees North (?)...I thought only negatives were for west and south.

Basically, you would either have negative longitude for west and negative latitude for south.

Oh, I see!

I don't see controlled experiment used.

Yes, the skepticism one is a sentence.

Scientific literacy is important when it comes to reading peer-reviewed journals that have complex, technical terms.

What sentences?

My hypothesis is that seeds germinate better in colder temperatures, but I will have to test that out.

Skepticism is apparent when discussing whether climate change is caused by humans or not.

My prediction for the experiment is that 20 out of the 100 seeds will germinate.

My data show that only 1 seed germinated, thus disproving my prediction.

The scientific method was applied to my seed experiment since I posed a question, constructed a hypothesis, tested that hypothesis, collected data, and disproved my hypothesis.

After I anazlyed the results, I found out that temperature does play a key role in seed germination.

Note sure what #8 means...

C. Muscle is a tissue

2(a-4) + 15 = 13

Distribute the 2:

2a - 8 + 15 = 13

Collect "like" terms:

2a + 7 = 13

Subtract 7 from both sides:

2a = 6

Divide by 2:

a = 6/2 = 3.

a = 3.

You would need to use cos theta since cos theta = adjacent/hypotenuse

cos theta = 13/23

cos^-1(13/23) = theta

theta = 55.6^o.

sqrt(275.12) = 16.5867416932922664.

EDIT: Note, this number is an approximation.

Use the $$\pm$$ key located under "2" and to the right of "0."
