Na, Rb, S, Cl rank the atoms from largest to smallest electronegativity. to rank items as equivalent overlap them.
please someone help me the question?

The correct sequence of electronegativity from largest to smallest are given below.

1) Chlorine (Cl)

2) Sulphur (S)

3) Sodium (Na)

4) Rubidium (Rb)

Explanation:

Value of electronegativity increases when we go from left to right in the periodic table and decrease from top to bottom.

Chlorine is the element of halogen group having higher electronegativity value in the period table. After chlorine, electronegativity value of Sulphur is higher because it belongs to group 6. Then sodium and in the last rubidium which has low value of

electronegativity.

c.) polymerase chain reaction

- "unlike the original dna fingerprinting method, dna profiling does not use restriction enzymes to cut the dna. instead it uses the polymerase chain reaction (pcr)? to produce many copies of specific str sequences. pcr is an automated procedure that generates lots of copies of a specific sequence of dna."

protein makes up the building blocks of organs, muscles, skin, hormones and pretty much everything that matters in your body.

some choices are:

peanut butter

seeds

eggs

yogurt

meats

fish

so pretty much meat, dairy, nuts, and grains.
