A faulty conus arteriosus would compromise on an effective gaseous exchange that keeps the blood of the
fish oxygenated for respiration of
tissues. The conus arteriosus is one of two accessory chambers found in most
fish with two-chambered hearts. The primary function of the conus arteriosus is
to prevent the backflow of blood and keep a steady flow of blood into the
ventral aorta and the gills.
Answer: C) the genes of this phage were made of DNA.
Explanation: the experiment described above wherein a radioactively labeled bacteriophage was allowed to infect bacteria ultimately led to the conclusion that the genes of the bacteriophage under study were made of DNA (a biopolymer of deoxyribonucleic acid, which is a type of nucleic acid composed of four different chemical groups, called bases: adenine, guanine, cytosine and thymine). Simply put, the experiment shows that the genetic material of the phage is DNA.
Metaphase. In all versions of metaphase the chromosomes line up in the middle of the cell.
