Resultant force = mass × acceleration, therefore acceleration = resultant force ÷ mass
Resultant force = 19 - 1.7 = 17.3 N
acceleration = 17.3÷2= 8.65 ms-2
Individuals with glucose-6-phosphate dehydrogenase deficiency have increased resistance to malaria because the parasite does not survive well in cells with oxidative stress.
<h3>What is the link between G6P deficiency and malaria?</h3>
- Glucose-6-phosphate dehydrogenase (G6PD) deficiency is an X-linked recessive disorder.
- G6PD protects cells from oxidative damage especially the RBCs whose main function is to carry oxygen.
- Mutation in the gene results in G6PD deficiency leading to oxidative stress which can lead to anemia (iron deficiency) as there is breakdown of RBCs.
- However, G6PD deficiency is quite common in parts of Africa, Middle East, and South Asia, which are the regions of high malaria endemism.
- This is due to natural selection in which G6PD deficiency is not eliminated from the population as it can protect people from malaria infection.
- Malaria parasite <em>Plasmodium</em> species does not survive well in cells with oxidative stress.

From what I can see in the picture, the cell appears that it would take up half of the microscopes view if it were to be pushed to the very edge on one side.
That would be the radius. The radius is half of the diameter, and half of 0.8 mm would be 0.4 mm. The length of the cell is about 0.4 mm.
Now for the width. Since the diameter of the FoV (field of view) is 0.8, we can see that the cell doesn't reach both sides of the circle it is in. It also doesn't appear to take up half of it. So, to get the aprox. width of the cell, we're going to half the radius.
Half of 0.4 mm is 0.2 mm, so the width of your cell is about 0.2 mm.
