Dr Chung is a biologist who works on diseases of the liver. She is studying infectious agents that invade liver cells. She has
narrowed down the cause of the disease she is studying to a type of virus or a protest
Which of the following characteristics would be the BEST choice for Dr. Chung to use in determining whether the infectious agent she is studying is a virus or a protist?
A
It infects both liver cells and red blood cells
It has proteins in its outermost layer.
O
It is capable of changing over time.
D
it has DNA as its genetic material

I’m not really sure: It is capable of changing over time(?)

Wetlands form where water and land meet. a lake with a wetland fringe can fill in with decayed plant and animal material to become a wet meadow. a pond can fill in to become a bog or fen. sediment can fill in a river marsh to become a swamp.flooding of coastal lowlands from rising sea levels has created broad coastal marshes that are protected from wave action by barrier islands or reefs. coastal wetlands also form when rivers deposit sediment as they reach the ocean. plants then take root and hold the soil firm against the forces of tides and waves.

I’m going to go with b!
