Please help and explain how u got ur answer. this makes no sense to me

a. AAA TCG

b. CGA AAT

Explanation:

DNA and RNA both have 4 nitrogenous bases, and the base pairing rule dictates which one each will bond with. If you have a hard time visualising the base paring rule, imagine it as two pairs of lovebirds.

So in DNA:

A ♡ T

(likewise) T ♡ A

C ♡ G

(likewise) G ♡ C

A will only bond with T, and C will only bond with G. Likewise, T will only bond with A and G with C. But you might've noticed that in your picture, there are no T! This is because this is a RNA strand instead of a DNA one, so the base paring rule is a bit different.

In RNA:

A ♡ U

(likewise) U ♡ A

C ♡ G

(likewise) G ♡ C

When transcribing RNA strands into DNA ones, the U's always translate to A, and the A's always translate to T's! You can think of the U's as the T's of RNA -- just (mentally) replace all the U's in the picture with T's, and the DNA base pairing rule applies. T's always translate to A, and the A's always translate to T's, right?

Another way you can make solving this question easier is to rearrange the bases vertically so it looks much more like the familiar base pairing rules layout!

U ♡ A

U ♡ A

U ♡ A

A ♡ T (because we're going RNA -> DNA, and DNA doesn't have base U!)

G ♡ C

C ♡ G

UUU AGC -> AAA TCG

In the answer you will see that all 4 DNA bases (A,T,C,G) are present :)

tdlr; if you're going RNA -> DNA, no U's in answer (replace them with T's!). If you're going DNA -> RNA, no T's in answer (replace them with U's!)

In either way both of them love A very much and will always translate into A :)

4.) metal

"-the movement of carbon from the nonliving environment into living things and back to the environment

-carbon is the essential component of proteins, fats, and carbohydrates (which make up all organisms)

-carbon exists in air, water, and living organisms

-producers convert carbon dioxide in the atmosphere into carbohydrates during photosynthesis

-bacteria in the atmosphere cycles through the system in filtration units

-in cellular respiration, carbon is released back into the atmosphere as carbon dioxide

-some carbon is stored in limestone (forming one of the largest "carbon sinks" on earth)

-largest carbon reservoir on earth= limestone

-carbon stored in the bodies of organisms as fat, oils, or other molecules may be released into the soil or air when the organism dies

-this may form deposits of coal, oil, or natural gas (fossil fuels, which increased the atmospheric carbon dioxide)

-fossil fuels store carbon left over from bodies of organisms that died millions of years ago

-they are located in the surface of earth, deep within the earth and beneath the ocean floor."
