NOT BIOLOGY ITS PHYSICAL SCIENCE how are the allotropes of carbon similar and how are they different?
Rashid [163]

Allotropes of carbon includes substances such as graphite, diamond or buckminsterfullerene.



They’re all similar in the thing that they’re all made out of carbon only.


However, their structure is different, such as graphite has a layer structure, diamond has a tetrahedral structure, and buckminsterfullerene has a spherical structure.  



Since they have different structures, they have different physical properties too. For example, diamond is hard because all the carbon atoms in the structure is held together by strong covalent bonds, while graphite are graphene layers that are held by weak intermolecular forces which makes the layers slide over each other easily thus making graphite soft.

someone has their blood tested and finds that their blood sugar level is 138. this is equivalent to 1.38%. How much glucose is i
disa [49]

The amount of glucose in each ml of their blood will be 0.00138 g.

<h3>Blood glucose concentration</h3>

The concentration of glucose in the person's blood is 1.38%.

This means that there is 1.38 g of sugar per Liter of blood.

1 Liter of blood contains 1.38 g of glucose, and there is 1000 mL in 1 Liter of blood.

1000 mL contains 1.38 g

1 ml contains = 1.38 x 1 / 1000 = 0.00138 g

This means 0.00138 g of glucose will be present in every 1 mL of the person's blood.
