Contains information that determines a cell's purpose and function.

cytoplasm
dna
the nucleus
an organelle

DNA is the correct answer.

Step-by-step explanation:

" Deoxyribonucleic acid (DNA) , a self-replicating material which is present in nearly all living organisms as the main constituent of chromosomes. It is the carrier of genetic information "

                               OR

" Deoxyribonucleic acid ( DNA) is a molecule composed of two chains that coil around each other to form a double helix carrying the genetic instructions used in the growth, development, functioning, and reproduction of all known living organisms and many viruses "

Hence, the correct answer among all the options  is DNA .

i.e.

DNA contains information that determines a cell's purpose and function.

answer:   28.56 feet (approx)

step-by-step explanation:

since, triangle abc has measure of angle c equal to 55 degrees, measure of angle abc equal to 90 degrees, and length of bc equal to 20 feet.

we have to find out the measurement of segment ab.

therefore, tan 55° =

but bc = 20 feet.

⇒ tan 55 ° =  

⇒ ab = 20 × tan 55 °

⇒ ab = 20 × 1.42814800674

⇒ ab = 28.5629601348   ≈ 28.56 feet
