Use the complementary rule: If we had a DNA strand of 20 nucleotides, and 6 of them
polet [3.4K]

Answer:

6 thymine, 4 guanine. 4 cytosine

Explanation:

Adenine pairs with thymine, so you need 6 of each

Cytosine matches with guanine, but the total of nucleotides is 20, so

6(adenine)+6(thymine)=12

20-12=8

8= 4(guanine)+4(cytosine)

Which stable element is used to determine the age of volcanic rock? argon O carbon-14 O O potassium carbon-12 Which stable eleme
Verdich [7]

Answer:

Argon

Explanation:

Argon is actually used to determine the age. It's called potassium-argon dating b/c when volcano erupts the rocks in it contain potassium. The potassium slowly decays and produces argon. Scientists measure how much argon is in a given volcanic rock and do math backwards to figure out how many potassium atoms were needed to produce the given amount of argon. We already know the rate at which potassium decays so then they put two and two together to find the age.

Here's a link with some cool info on it:
