What process occurs during transcription? (2 points)
iVinArrow [24]

Answer:

Copying of DNA to form an mRNA strand

Explanation:

In transcription, DNA is copied to form an mRNA strand with complementary bases.

The DNA strand being copied during the process is called the template strand, and the mRNA that is made will be created from that strand.

This is the first step of protein synthesis.

This strand of mRNA is further used during translation, where it is used to code for amino acids to make proteins.

So, the correct answer is Copying of DNA to form an mRNA strand

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.
