Answer:
Dacitic magma is formed by the subduction of young oceanic crust under a thick felsic continental plate. Oceanic crust is hydrothermally altered causing addition of quartz and sodium.
The viscosity of magma is determined by its silica content.
Basalt magma, on the one hand, which is often
of low viscosity, has a low silica content of approximately 50% or less. Rhyolite magma, on the other hand, has high viscosity due to the high silica content of
approximately 70% and more.
Gas content and temperatures of the magma are the other factors
that determine an explosive or
nonexplosive eruption. High temperatures
and high gas content (coupled with high viscosity)
cause violent explosions.

Answer:
A
. proteins can take a variety of shapes, and nucleic acids tend to form linear chains
Explanation:
Proteins are consist of 50 and 2000 amino acid long and can take variety of shapes in living organisms. Two types of proteins that found in living cells are globular proteins and fibrous proteins and they have different shapes. Example of globular protein is hemoglobin and fibrous proteins are hair and nails, and collagen.
Nucleic acids tend to form linear chains from the monomers called nucleotides. Nucleotides have three components: nitrogenous base. phosphate group, and pentose sugar (5-carbon sugar) that together forms a definite linear shape. It is found in DNA of living organisms.
Hence, the correct option is "A
. proteins can take a variety of shapes, and nucleic acids tend to form linear chains".
