Question

after the covid - 19 virus breaks through the plasma membrane, it encounters a network of protein cylinders and filaments collectively known as the cytoskeleton. the virus’s genetic material travels to the endoplasmic reticulum (er), an extensive and interconnected network of sacs that are classified into two types: the smooth er where lipids and hormones are produced, and the rough er where some proteins are synthesized due to the presence of ribosomes embedded on the surface. complete the following passage. evidence suggests that viral particles form their external envelope at the er or the , where proteins and lipids are packaged and directed to their final destinations either inside or outside the cells. even when the virus replaces and leaves the cell, viral proteins still hijack the cell and can target the , a tiny power plant that fuels cellular activities. viral proteins also bombard the cell’s , the control center of the eukaryotic cell. during infection, viral proteins block the to prevent chemical messages from leaving the nucleus. in other words, the virus prevents the cell from sending a warning message to the immune system. nuclear pores lysosomes nucleus mitochondria nucleolus golgi apparatus cytoskeleton chloroplasts

Explanation:

The Golgi apparatus packages and directs proteins and lipids. Mitochondria are the power - plants of the cell. The nucleus is the control center of the eukaryotic cell. Nuclear pores are used for the transport of chemical messages in and out of the nucleus.

Answer:

Golgi apparatus
mitochondria
nucleus
nuclear pores
