Which statement best explains why gneiss is composed of layers but there are no layers in granite?

1 answer:

8 0

The granite rocks are formed by the slow crystallisation of the magma below the earth surface, due to slow crystallisation of the magma, the rocks formed are uniform, and have no layers.

The gneiss rocks are formed by the metamorphosis of the granite and the sedimentary rocks. They are formed by the action of high temperature and high pressure. The gneiss rock is layered caused by the segregation of different types of rock, mainly made up of light and dark silicates.

Hence, the correct answer is option

C. Granite is formed due to the slow cooling of magma below Earth's surface and gneiss is formed due to metamorphosis.

7. Phytochrome prevents seeds of some plants from germinating when they are in deep shade by the: absorption of far-red waveleng

SIZIF [17.4K]

<h2>Function of Phytochrome </h2>

Explanation:

The color of light that they absorb maximally by the two types such as Pfr is a blue-green structure that ingests far-red light (730 nm) and Pr is a blue structure that retains red light (660 nm)
Pfr assimilates far-red light, it is changed over to the Pr structure
Pfr can spontaneously revert to the Pr form structure in obscurity dark over time = dark reversion Pfr is additionally helpless to proteinases
Pfr contains some red light, so in red light 15% Pr and there is a parity of 85% Pfr.
The phytochrome (Pr) is changed over to the organically dynamic structure red light with the Pfr under illumination
Darkness and Far -red light convert the particle back to the inactive form.
