Answer:
Plantae, Fungi, or Protista
Explanation:
Hey there!
An ion is any atom with an electric charge. This can be negative or positive.
To see which one of these is an ion, first see what causes an electric charge. Positive charges are caused by protons. One proton = one positive. Negative charges are caused by electrons. One electron = one negative. Thus, when the number of protons and electrons are equal, this makes it so there is no overall charge. Thus, to make an ion, the number of protons and electrons must be unequal.
When we look at the answer choice, we can see that the number of protons and electrons are equal for every single choice except for choice b. Thus, your answer is b.
Hope this helps!
DNA makes up genes. Transcription: The info stored in the gene's DNA is transcribed to RNA in the cell nucleus. The type of RNA that contains the info for making a protein is called messenger RNA, also known as mRNA. It carries out the information from the DNA, out of the nucleus, and into the cytoplasm. Translation: This happens in the cytoplasm. It is where the mRNA interacts with the ribosome, which "reads" the sequence of mRNA bases. Three bases make a <em>codon</em>, which usually codes for one particular amino acid, which is building blocks of proteins. Then, another type of RNA called transfer RNA, aka tRNA, assembles the protein by folding. This continues until the ribosome reaches a stop codon.
