Answer:

D.

Explanation:

Use the cell theory to explain why a stuffed animal dog is not alive
notka56 [123]
The cell theory consists of the rule that all living things must contain cells. The stuffed animal (since it is nonliving) has no cells. More evidence to prove this is that the stuffed animal comes from a manufacturer not other cells.

Mafic lava tends to have low silica content. Based on this, which of the following statements about mafic lava is most likely tr
sashaice [31]

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.
