The isotope has a half-life of 5730 years.

In 5730 years, the isotope (Carbon-14, to be more exact) will lose 50% of its mass, meaning that in 11460 years, 25 grams of Carbon-14 will remain.

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 two major components of extracellular matrix?
Advocard [28]

The two main components of the extracellular matrix are Elastin and Collagen.

The extracellular matrix is an intricate macromolecular network that is found in the extracellular space. The matrix is composed of polysaccharides and very diverse proteins, locally secreted and assembled forming a complex network that surrounds the cells. The matrix is highly developed in connective tissue and its derivatives. The extracellular matrix is formed mainly by proteins, glycosaminoglycans,proteoglycans and glycoproteins, organized in diverse networks that constitute the different tissues. <em>The most abundant proteins are collagen and elastin.</em>

Collagen is a family of very abundant proteins in the body of animals. Collagen molecules can represent 25 to 30 % of all body proteins. Its main mission in the tissues is to form a framework that supports the tissues and that resists the forces of mechanical tension.

The elastin molecules are very close to each other through links between the regions rich in the amino acid lysine. It is an abundant protein in may extracellular matrices and appears as a component of the so called elastic fibers, which are onsoluble aggregates of proteins.
