Answer:
200 g of cheese
Explanation:
From the table attached, we can see that each 100 g of cheese contain 22.5 g of protein. For us to calculate the amount of cheese needed to provide about 45 g of protein, we use the formula:
Amount of cheese for 45 g of protein = (100 g of cheese/ 22.5 g of protein) * 45 g of protein
Amount of cheese for 45 g of protein = 200 g of cheese
Therefore 200 g of cheese would be needed to provide 45 g of protein.
This is because the GP120 protein
of the HIV virus that forms the ‘knob’ is
essential for the infection of CD4 cells
of the immune system by the virus. The glycoprotein is, therefore, a good
target for vaccines especially since the
molecule is highly conserved because most mutations in the region could be highly deleterious to the virus.
