Answer:
The two types of lipoproteins are low density lipoprotein and high density lipoproteins
Explanation: As applying to low density lipoproteins (LDL), these are sometimes called the bad cholesterol because a high LDL level leads to a build up of cholesterol in the arteries. This condition narrows the arteries and increases the risk of heart attack, Strom and peripheral artery diseases.
High Density Lipoproteins (HDL), also known as the good cholesterol acts as a scavenger carrying LDL away from the arteries and back to the liver where the LDL is break down and passed from the body.
Answer:
A. It contains fewer volatile gases.
Explanation:
Mafic lava have a composition of about 45-55% silica with high amount of Fe, Mg, Ca.
The silica content is quite low compared to those of granitic magma whose silica content can reach up to about 60%.
What determines the viscosity of magma is basically the silica content of the magma and the temperature of the magma. Viscosity is the resistance to flow.
The higher the silica content, the lower the viscosity and the higher the amount of volatile gases. Such type of magma is the granitic magma. Granitic magma due to their viscosity flows slowly.
The lower the silica content, the higher the viscosity and the lesser the presence of volatile gases in them. Such an example is Mafic magma. Mafic magma flows very slowly with low amount of dissolved gases.
Answer:
The correct option is A. Matter is conserved during the burning of wood
Explanation:
One of the major theories of matter states that the amount of mass at the start of a reaction is equal to the amount of the mass at the end of the reaction.
As in Joan's study, he shows that the amount of carbon atoms remain 840 during each of the combustion reactions. The number of carbon atoms in wood at the start of the reaction was equal to the number of carbon atoms in carbon dioxide at the end of the reaction. Hence, Joan's model supports the theory that matter is conserved during the burning of the wood.
