Urethra. <span>
<span>It is
a narrow tube that is connected to both the bladder and the ejaculatory duct
(in that order). It is therefore responsible for transporting urine and semen
from the body. It is a fibro-muscular duct that is housed by the penis. It
outer part of the urethra contains some sphincter muscles that allow
voluntary control over urine while the inner part of the urethra allows for
involuntary transmission of semen during ejaculation.</span></span>

The correct option is C.
The tRNA is the only type of RNA that can come in contact with the ribosomes in the cytoplasm. During the translation process of protein synthesis in the cell, the tRNA function by carrying amino acid to the ribosomes and matching the codon in the mRNA with the amino acid it codes for. Thus it acts as a bridge between mRNA and ribosomes.
Antigens is the correct answer
Isotopes vary in the number of neutrons, and thus, the atomic mass varies also since neutron mass is significant.
