Answer:

on the surface rapidly

Explanation:

Obsidian glassy texture indicates that the rock formed on the surface rapidly.

Like every other magma, the condition of the environment determines how the magma cools and solidifies.

  • When magma cools rapidly, nucleation centers will be difficult to come- by ..
  • At nucleation centers, minerals aggregates and grows to form different grain sizes.
  • When rapid cooling occurs, not enough time is given for the aggregation around the nucleus.
  • This leaves a rock mass that is finely grained.

Which means of particle transport is shown in Figure 7–4 above?
sattari [20]
The correct option is D.
When it comes to movement of particles in an out of cells, there are two basic types of transportation, these are passive and active transportation. The passive transportation of particles does not require  the use of energy while the active transport system requires the use of energy in the form of ATP. From the diagram given in the question, it can be seen that energy is involved in the process. Energy is mainly needed to move the particles against the concentration gradient since the inside of the cell is highly concentrated while the outside has low concentration. <span />
