Frequency= 1/period
hence ans= 1/0.25
= 4s
Answer: I think the answer is C
Explanation:
Answer:
As proteins vary widely in structures than that of nucleic acid there will be greater structural and functional diversity of proteins than nucleic acid.
Explanation:
Proteins are the macromolecules which have more structural diversity than any other macromolecules such as carbohydrate,lipid,nucleic acid.
The are 4 types of protein structure primary structure,secondary structure,tertiary structure and Quaternary structure.Due the existence of many types of structure various protein exhibit various functions.
On the other hand nucleic acid such as DNA has widely accepted secondary structure discovered by watson and crick.As a result there is no such structural diversity exist in nucleic acid.

Answer:
3.61 * 10 ²⁴atoms.
Explanation:
Moles is denoted by given mass divided by the molecular mass ,
Hence ,
n = w / m
n = moles ,
w = given mass ,
m = molecular mass .
From the question ,
w = 582 g
m = 194 g/mol
The number of moles can be calculated from the above formula , and substituting the respective values ,
n = w / m = 582 g / 194 g/mol = 3 mol
In the molecular formula of caffeine ,
<u>In 1 mole of caffeine their are - 2 moles of Oxygen.
</u>
Therefore , in 3 moles of Caffeine there will be 6 moles of oxygen.
As well know ,
one mole of any substance contains 6.023*10²³ atoms,
Therefore , in 6 mol of oxygen = 6 * 6.023*10²³ atoms = 3.61 * 10 ²⁴atoms.
