Answer:

Some islands have older islands at one end of the chain and younger islands at the other end. Example is the Hawaiian Islands.

Explanation:

Volcanic mountains or islands are formed when the tectonic plates in the earth’s crust converges. The string of Hawaiian volcanic islands were formed as a result of the movement of the Pacific plate over a fixed hotspot, where the magma rises upward and erupts on the seafloor. The northwestern islands are older than the islands to the southeast side of the Hawaiian islands.

The age of a volcanic rock is calculated by measuring the amount of argon and the amount of radioactive potassium present in the rock. These measurements are the supporting evidence which showed that the southeastern end of the chain is younger than the northwestern part of the chain. The volcanic islands gradually subside and erode as they age, so the older islands have much lower elevations than the newer islands. This is another evidence which supports the conclusion.

denis-greek [22]

Answer:

The correct answer is - 2 genes.

Explanation:

The number of genes involved in the coloration of the strain of cereal grain, could be either dark tan, medium-dark tan, medium tan, light tan, or cream-colored if all F1 are medium tan when crossed a dark tan crossed with cream-colored, can be calculated as follow:

suppose there are only two gene - TT dominant over tt and CC dominant over cc

then the cross would be - RRCC - rrcc

gametes - RC and rc

Cross F1: RrCc

Self cross in F2:

offspring by Punnet cross are:

RRCC -->1/16

RRCc, RrCC .---> 4/16

RrCc, RRcc, rrCC--->6/16

rrCc, Rrcc--->4/16

rrcc ----> 1/16

thus, the correct answer is 2 genes

Cornelius Agrippa (1486-1535) was a German mystic who practiced a "science" that combined alchemy, magic, mysticism, and astrology. Two of his books are Three Books of Occult Philosophy and On Calling Spirits. Through the writing of Agrippa, Frankenstein becomes very interested in alchemy, which is a pseudoscience whose main object is to find a way of turning base metals into gold. You could say that Frankenstein adapted the thinking of the alchemists and instead of transforming other metals into gold attempted to transform a corpse into a living being.

An interesting story about Agrippa concerns sightings of him after his death:

There were rumors that Agrippa had summoned demons on his death bed, and that a black dog roamed the countryside as his familiar. The black dog appears in tales as Faustus, Mephistopheles, and even as a grim in the Harry Potter series.
