Ascientist thinks he has discovered a drug that interferes with the functioning of a virus in the human body. to effectively block infection the drug can? a- weaken viral respiration. b- destroy viral mitochondria. c- reduce the ability of the virus to absorb cells. d- prevent the virus from entering cells.

The control of virus infection is complicated compared to bacteria since the virus   either enters into the host cells or used the host cell components to create new cells that is released to affect new cells. Hence it has been a challenge to isolate the virus particle and affect them with chemical components without causing damages to the host cells.

Hence antivirals are drugs that are designed to inhibit their activity. They will block the activity of the virus from entering the cells and make them into host. Hence D is the right option

the framers of the constitution insisted that federal judges be nominated instead of elected due to their desire to have judges above the shifting whims of the masses.

the hope, whether achieved or not, was that federal judges would only be beholden to the law and that by not having judges be elected, they would be protected if that law dictated an outcome that ran counter to popular opinion.

the fossil record provides evidence of a common ancestor to many species.
