A researcher is testing a new antiviral agent that reduces the severity of a highly contagious strain of the flu virus. She has found that the antiviral agent only it administered within 48 hours of the onset of symptoms. This information would lead the researcher to believe the virus

virus is at its infant stage for the first 2days and develop into adulthood afterwards hence the virus becomes resistant to the antiviral agent.

Explanation:

that would be called plucking : )

explanation:

''plucking, also referred to as quarrying, is a glacial phenomenon that is responsible for the erosion and transportation of individual pieces of bedrock, especially large "joint blocks". as a glacier moves down a valley, friction causes the basal ice of the glacier to melt and infiltrate joints (cracks) in the bedrock."

carbon traps heat so more of it makes it hotter causing global warming. during the ice age carbon levels in the atmosphere were low so it got very cold. so the common things between them is carbon levels in the atmosphere.
