Bacteriophages are a type of virus that infects bacteria. Scientists have started to use these bacteriophages to move genetic information from one bacterium to another. Which characteristic of a virus is an advantage and why?

A
The ability to integrate its own DNA into the host’s DNA makes it possible to transfer the integrated DNA to another organism.
B
The ability to utilize the hosts’ protein synthesis machinery where copies of synthesized proteins remain stored.
C
The ability to only infect a limited range of hosts helps to transfer genetic material more efficiently.
D
The ability to assemble itself inside the host cell makes the transfer more efficient and independent.

The tasmanian devil, a marsupial carnivore, is facing extinction due to devil facial tumor disease (dftd) which causes bulging cancerous lumps and lesions to erupt around the face and neck — often causing enough deformation to make seeing or eating difficult. dftd has evolved into a contagious cancer, a trait that is unique among cancers. devil mating behavior involves biting around the head and neck, allowing cells from one individual — especially cells from the crumbly dftd tumors — to be transferred to the wounds or face of a new individual. this marsupial was once found across australia, but sea levels rose, isolating the tasmanian population, while the australian population went extinct. what would be an outcome of genetic isolation that is likely to have impacted the spread of dftd? a) reduced territory puts diseased individuals in greater contact with non-diseased ones. b) inbreeding results in less variation in facial features so the cancer is generally fatal. c) genetic isolation has made it difficult for scientists to develop a vaccine against dftd. d) the lack of genetic variation in the immune system of tasmanian devils minimizes resistance to the disease.

What happens during interphase? (1)the nucleus grows to its full size. (2)the cell grows to its full size. (3)the nucleus divides into two nuclei. (4)the cell divides into two cells.
