Gabriela is sick with a bad cold. her immune system is defending her body against the invading virus. the first line of defense is cells called macrophages, which attack viral particles. the cells eliminate viral particles in a process called endocytosis. arrange the steps of endocytosis in order of what occurs. 1. cell surface receptors bind to the viral particle. 2. lysosome within the cell encloses the viral particle. 3. viral particle is surrounded by the cell membrane. 4. cell membrane curves around toward the cell's interior. 5. lysosome's digestive enzymes destroy the viral particle. 6. cell recognizes the viral particle as foreign material. 1. 2. 3. 4. 5. 6.

Macrophages are phagocytic cells which are involved in endocytosis. It is a process of engulfing antigen. Endocytosis occurs when a cell destroys something such as a virus or an infected cell.

The  correct steps of endocytosis in chronological order as follows:

6. Cell recognizes the viral particle as foreign material.

1. Cell surface receptors bind to the viral particle.

 4. Cell membrane curves around toward the cell's interior.

3. Viral particle is surrounded by the cell membrane.

2. Lysosome within the cell encloses the viral particle.

5. Lysosome's digestive enzymes destroy the viral particle.

the answer is; comparing the frequency of collisions with and without the device

this makes the anti-collision system an independent variable and the collisions a dependent variable. if there are fewer collisions with an anti-collision system that without, then it can be stated that the system is a success. essentially, collisions under an anti-collision system are compared with the frequency of collisions by cars with the human drivers.
