Individuals with glucose-6-phosphate dehydrogenase deficiency have increased resistance to malaria because the parasite does not
Alexus [3.1K]

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.

What are the similarities in the way a barchan forms and the way a hooked spit forms?
choli [55]

Answer:

The similarities in the way barchan and hooked spit forms are:

First, they are formed from sediment or sand movement.

Second, this movement makes them have a peculiar curved form that provides them their major characteristic.

Explanation:

First of all, barchans are sand formations that are created after the accumulation of sand in a place is moved by the wind and provides them a curved form. However, they exist only out of the sea.

Second, hooked spits are formations that happen after sea movement displaces the sediment to create a curved structure that can only exist in the sea. These formations affect the strength and direction of the waves in the sea due to their curved form.

A. create a data table to compare and contrast the physical features of the three skeletons.
Natalija [7]

Comparing the physical features of the three types of skeletons

<u>Endoskeleton :</u>                                        

Less Flexible than cartilage    

<u>Exoskeleton :</u>

very rigid and hard    

<u>Hydrostatic skeletons  </u> :  

Less rigid and very flexible

<h3>Physical difference of the types of skeletons </h3>

The endoskeleton is the internal skeleton present in vertebrates in the form of bones which enables the movement of animals while supporting the organs of the body to remain in position. they are less flexible when compared to cartilage. Exoskeletons are outer skeletons which protect organisms and also enables them to move freely. They are very rigid and hard.

Hence we can conclude that the comparison between the types of skeletons are as listed above.
