Which nitrogen base sequence is the partner of c–a–t–c–g–a?

a. c–a–t–c–g–a
b. g–t–a–g–c–t
c. t–g–c–t–a–g
d. g–c–a–t–g–t

B.)  G-T-A-G-C-T

Explanation:

Correct on E. 2020 assignment.

answer: -

reaction:

na + cl ⇌ nacl

balanced chemical equation:

na + 2cl ⇌ nacl2

sodium + clorine goes to form sodium chloride (table salt).

the product is nacl2.

and the reactants are na and cl.

(note: if you don’t know what ⇌ means, read below: -

⇌(double head arrow) means reversible reaction).

the answer is:  

line graphs show patterns in data with variables that change over time; whereas, circle graphs show data as parts out of a whole (such as out of 100%).
