Answer:
The correct answer is:
D. Gene A is assorting independently of genes B and C, which are linked.
Explanation:
According to the text it is possible to deduce that the first allele of gene A appears with allele of gene B or C half of times. On the other side alleles of genes B or C appear at the same time in 14.4% of the cases. This information shows how A is and independent variable and how B and C are related as they appear together as well.
C. according to Earth's existing magnetic field.
Answer:
Principles of Geology
Explanation:
J. Henslow gifted Darwin the first volume of Principles of Geology, written by Charles Lyell. The book explains about the old age of the earth. Accordingly, the slow rate of several geological processes suggests that the earth is very old.
Darwin read the book as the ship was crossing the Atlantic and learned about geological processes occurring over the millions of years. For example, he learned that the earth's surface was not formed by some catastrophic event.
In his book, Lyell explained the slow and gradual geological processes like erosion gave rise to the vast landscapes present on the earth's surface.
Darwin compared the time taken by geological processes to form the earth's surface and reasoned if these millions of years were enough to support the evolution of species.
B. because the rock is formed and it goes younger as it grows the rock is still old on the inner layers but it adds new layers as it goes
