Answer:
The correct option is c ( <span>sexual reproduction joins two cells that each have half the total chromosome number).
Reason:
Meiosis occurs only in reproductive cell in which the number of chromosome reduce to half. This phenomenon is very imoportant and essential for maintaining the number of chromosomes in species.</span><span />

The respiratory system and the circulatory system function together as a “coupled unit” delivering the body's oxygen and nutrients and taking away carbon dioxide and wastes to maintain homeostasis.
The sequence of the mRNA complementary strand for the given sequence of the strand will be 'AUG CUU GAG GGG UCC'.
The name of the decoding process is translation, and ribosomes are involved in this process.
The process of the synthesis of protein begins with the process of transcription. In this process, the DNA is unwinded, and the RNA polymerase binds to the promoter region and transcribes the codon corresponding to the amino acids. The transcribed mRNA strand is then translated by the ribosomes. The ribosomes reads the codons and the tRNA brings and attaches the related amino acids in a sequence resulting in the formation of a protein.
The protein synthesis is crucial as the proteins are responsible for the structure and functions of the different cells of the body.
Sickle cell anemia is a genetic disorder, in which a point mutation changes the codon for the glutamic acid to valine. This leads to the formation of an abnormal shape of the hemoglobin which decreases the ability of it to efficiently transport oxygen.
