dentify what kind of text type is the following paragraph. Write the letter of the correct answer.
1. Researchers have used cryogenic electron microscopy to show that
coronaviruses enter human cells through an interaction with angiotensin-
converting enzyme 2 (ACE2).
Scientists exploring how coronaviruses like COVID-19 infect human cells
have shown that the SARS-COV-2 Spike (S) glycoprotein binds to the cell
membrane protein angiotensin-converting enzyme 2 (ACE2) to enter human cells.
COVID-19 has been shown to bind to ACE2 via the S protein on its surface. During
infection, the S protein is cleaved into subunits. Si and S2. Si contains the
receptor binding domain (RBD) which allows coronaviruses to directly bind to the
peptidase domain (PD) of ACE2. S2 then likely plays a role in membrane fusion.
What is the purpose of the text?
a. explain how Covid-19 enters human cell.
b. classify the different corona virus.
c. entertain the readers about the effect of covid-19.
2. As the Covid-19 pandemic takes turn to the lives of people around the
globe. The government declares community quarantine in their respective

lastly is the General Community Quarantine. Each level has its own restrictions
