Answer:
Explanation:
In a cross-section of an adult tree trunk, the outer layer that interacts with the environment is called periderm (Layer D). The second layer that follows the periderm is the phloem (Layer C). The next layer is the cambium, which produces phloem cells and xylem cells (Layer B). The secondary xylem follows the vascular cambium (Layer A) and finally, the medulla is located in the middle of the trunk.
The secondary xylem proceeds from the vascular cambium activity. Its cells are orientated in different ways composing the vertical/axial system and the horizontal/transversal system. The secondary xylem is essential to the tree growth in high because of its resistance and the capacity to transport water long distances. Secondary xylem functions are to transport water and minerals through its vessels and tracheids, to provide support and resistance to the plant, and to store reserve substances.
You have to find the similarities and differences of intrusive and extrusive igneous rocks for the first question. The second one requires you to find out coarse-grained rocks are formed, the third is asking how igneous rocks are classified according to its structure, like the construction of the rock(what it is made up of). The fourth is asking you how fine grained-igneous rocks are made basically, the fifth is asking you how do igneous rocks with that glossy fine stain, how are they made.
