Answer: Option (d) is the correct answer.

Explanation:

A chemical formula is a symbolic representation of a compound or molecule that shown how many atoms of an element are present. Also, it helps in known the kind of atoms present in a compound.

For example, chemical formula of calcium chloride is CaCl_{2}.

So, it shows that there are two chlorine atoms and one calcium atom.

Also, it shows that bonding is taking place between a metal and a non-metal.

Thus, we can conclude that we get to know about the number and kinds of atoms in the compound by looking at its chemical formula.

Choose the answer that places the following events of protein synthesis in the proper order.
Fofino [41]

A) 3,5,1,6,2,4 is the correct order for the  events of protein synthesis.

<h3>What is protein synthesis?</h3>

Protein synthesis (translation) is the process of creating a polymer of an amino acid chain that results in the production of a functional protein. It entails reading information from mRNA (messenger RNA) and assembling an amino acid chain. Ribosomes are the structures responsible for protein chain synthesis.

Protein synthesis is an important process because we rely on our bodies to build the proteins we require to perform important functions. Without protein synthesis, our bodies will be unable to produce hormones, enzymes, and even new muscle.
