The viral component that is responsible for inducing a host cell to take in an influenza virus by endocytosis would be hemagglutinin. It is a glycoprotein that can be found in the surfaces of an influenza virus and is essential to its entry to hosts. It is the substance that is responsible for allowing the virus to bind to cells especially cells in the respiratory tract. It also causes the RBC or the red blood cells to agglutinate or clump together. The hemagglutinin is cylindrical in shape and is 13.5 nm in length. It has 18 different antigens wherein they are named H1 to H18.

Answer: Percolation
Explanation: It is the ability of water to sip in into the ground. Percolation is the process wherein the ground absorbs water up to the amount it can hold. When the soil or ground is saturated with water it loses its ability to absorb water and causes it to run off. Unsaturated ground can absorb more water through percolation process.
They carry a combination of their genetic traits.
