When the influenza virus enters an epithelial cell, the infected cell responds by posting antigens and acting as a flag for cytotoxic T cells.
<h3>What is the cell-mediated response?</h3>
The cell-mediated response is a type of immune response where the organism is able to respond to pathogens by immune cells.
Macrophages (as well as other immune cells ) can act during cell-mediated immune responses.
In conclusion, when the influenza virus enters an epithelial cell, the infected cell responds by posting antigens and acting as a flag for cytotoxic T cells.

Both gymnosperms and angiosperms have vascular tissue that is specialized for transport of minerals, water, and organic compounds. Also, both gymnosperms and angiosperms have seeds. The only difference is that angiosperms have seeds hidden in the ovary while gymnosperms have seed on the surface of the scales of the cones.
Answer:
B. After clearcutting, plant uptake stopped and nitrogen accumulated in the soil.
Explanation: Clear cutting leaves the soil bare and allows for direct penetration of sunlight this increases the soil temperature which favors the activity of soil microrganism. This microrganism activity increase the production of ammonium and nitrate hence the increase in soil Nitrogen level. Clearcutting then allows for accumulation of Nitrogen produce due to removal of plant or forest tree that could use up the Nitrogen produced.
Plants and animals live in interacting, interwined communities. There is a characteristic set of species in different environments. For example, certain species of trees, shrubs, ground cover, arthropods, reptiles, mammals, birds etc. live in a temperate forest environment. A completely different set of creatures live in a marsh, or a grassland or an agroecosystem. However, the relationships between these groups can be defined by the ecological role they play, the flow of energy between them and the cycling of nutrients between them. This is a fancy way of saying "everything is connected"! And if you change one part of the system, something else changes. In an ecosystem management decision, you hope you know what those consequences of your actions are!) This is important in managing agroecosystems as well.
