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:

A. It contains fewer volatile gases

Explanation:

The mafic lava is a lava type that has low viscosity. The reason for that is its composition, being very rich in magnesium and iron. Because this type of lava is low in viscosity, it is unable to contain the majority of the gases and water in it, as they find it relatively easy to ''escape'' from it. That results in much calmer eruptions of the volcanoes that produce mafic magma, with explosions almost never occurring, and even if they do they are very small.

Gregor Mendel demonstrated that traits are passed from parents to offspring independently of one another under all circumstances
DedPeter [7]
<span>In this item, we are given that a certain biologist in the name of Gregor Mendel demonstrated that the traits are passed on from the parent to the offspring independently of one another. Because other scientists have observed this trait as well, this observation now became a law. Thus, the answer to this question is the first choice. </span>

Answer: Water is drawn in through small openings on a sponge's body called OSTIA.

The supportive skeleton of a sponge contains SPICULES which provide protection from predators.

Explanation:

Sponges refer to any of the aquatic animals of the phyllum porifera which is normally characterized with porous structures and has horn-like calcareous internal framework.

Sponges usually have multiple pores called "OSTIA" on their bodies that allow water to enter them.

Most sponges are sessile and because of this, they can't run away from predators. They usually have sharp "SPICULES" which are part of their skeleton that provide them some certain degree of defense. Apart from this, they also produce toxins which poisons predators that attempt to consume them

IrinaK [193]

Nucleus can be defined as a large organelle found in the Eukaryotic cells and it is also  know as the cell's command center,thus it controls the activity of the cells

Explanation:

  • The answer to the above question is (c )nucleus. During the cell cycle the nucleus of the cell mediates the replication of the of the DNA and controls the gene expression.
  • The nucleus contains a structure which is known as nucleolus and which is made up of protein and ribonucleic acid(RNA)
