Where does lava in volcanoes come from?
Stella [2.4K]
Magma can push through holes or cracks in the crust of the volcano, causing a volcanic eruption. Which is when magma flows or erupts onto earth's surface, which is what you call lava (whenever it goes onto the earths surface).

Based on the passage, what is the structure of the product of the reaction between 8-hydroxyquinoline-5 sulfonate and hrp?.
Mashutka [201]

A because the end result of this reaction is a radical created by the oxidation of an aromatic amine's or phenol's ring substituent. The hydroxyl group of a phenol acts as the ring substituent in this situation.

<h3>Which two enzyme types are required for the two-step process of converting cytosine to 5 hmC?</h3>
  • The methyl group is transferred to cytosine in the first stage, and it is then hydroxylated in the second step.
  • Therefore, a transferase and an oxidoreductase are the two groups of enzymes required.

<h3>Which kind of interaction between proteins and the dextran column material is most likely to take place?</h3>
  • Hydrogen bonding because the glucose's OH would form an H-bond with any exposed polar side chains on a protein surface.

<h3>Two out of the four proteins would adhere to a cation-exchange column at what buffer pH? </h3>
  • Only positively charged proteins can bind to a cation-exchange column, and this can only happen when the pH is lower than the pI.
  • Proteins A and B would both be positively charged at pH 7.0.

a block of iron has the dimensions of 3.00 cm x 3.00 cm x 3.00 cm. it has a mass of 213 g. when placed in water, the block sinks
Art [367]

 When the block  of iron is  placed  in water  the volume of water that   is  displaced is  27.0  cm³


  <u><em> calculation</em></u>

The  volume water that is displaced is equal to volume of block  of the iron


volume of block of iron = length x width x height

   length= 3 cm

   width = 3  cm

 height = 3 cm

volume  is therefore = 3 cm  x  3 cm x  3  cm = 27  cm³   therefore the volume displaced  = 27 cm³  since the volume of water displaced  is equal to  volume of block.
