Shannon is correct. I think of it as a microscopic spider. Imagine you touch something at Walmart and get your hands infected you wipe your nose with your hands. The virus enters the nose or wherever you let it go to. It crawls into one cells(now host cell) it injects genetic material of the virus into the host cell, the host cells the explodes and the micro-microscopic particles spread onto more and more cells and break those. While your immune system tries to defend you against them, sometime your immune system wins and you don’t get sick but sometime is looses and that is how we get sick.

Answer: viral invasion.

Explanation:Cytopathic effect or cytopathogenic effect (abbreviated CPE) refers to structural changes in host cells that are caused by viral invasion. The infecting virus causes lysis of the host cell or when the cell dies without lysis due to an inability to replicate. Both of these effects occur due to CPEs.

Whales have pelvic (hip) bones, which are evolutionary remains from when their forefathers walked on land about 40 million years ago. Common belief has long assumed that such bones are merely vestigial, slowly withering away like human tailbones. Thus option C is correct.

<h3>What is the new research from USC and the Natural History Museum of Los Angeles County (NHM) has to say ?</h3>

New research from USC and the Natural History Museum of Los Angeles County (NHM) contradicts this belief, discovering that not only do those pelvic bones have a role, but their size and perhaps shape are impacted by sexual selection processes.

Therefore, small, shrunken hip bones of whale are no longer beneficial for survival and are considered vestigial. So, the best option is C among the other options available. Thus option C is correct.

The emergence of resistance is a result of EVOLUTION by natural selection. It is a major evolutionary force.

<h3>Evolution and natural selection </h3>

The term evolution refers to the biological process of descendence with modification.

Natural selection refers to the differential survival or reproduction of the organisms better adapted to a given environment.

In this case, the presence of the pesticide generates an evolutionary constraint, thereby selecting pesticide-resistant individuals in the population.
