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.

Why is soil important? Soil is our life support system. Soils provide anchorage for roots, hold water and nutrients. Soils are home to myriad micro-organisms that fix nitrogen and decompose organic matter, and armies of microscopic animals as well as earthworms and termites.
What is soil erosion? Soil erosion is a naturally occurring process that affects all landforms. In agriculture, soil erosion refers to the wearing away of a field's topsoil by the natural physical forces of water (Figure 1) and wind (Figure 2) or through forces associated with farming activities such as tillage.
what human activities are responsible for soil erosion happening at advance rates? Ploughing, unsuitable agricultural practices, combined with deforestation and overgrazing, are the main causes of human-induced soil erosion
What are some effects on soil loss? The effects of soil erosion go beyond the loss of fertile land. It has led to increased pollution and sedimentation in streams and rivers, clogging these waterways and causing declines in fish and other species. And degraded lands are also often less able to hold onto water, which can worsen flooding.
What can be done to prevent soil erosion? Maintaining a healthy, perennial plant cover.
Mulching.
Planting a cover crop – such as winter rye in vegetable gardens. ...
Placing crushed stone, wood chips, and other similar materials in heavily used areas where vegetation is hard to establish and maintain.
