The answers would be:
Layer D
Layer C
Layer B
Layer A
Layer E
Fault F
If you'd like to know why, here's more about the question:
The law of superpo sition states that the lower the layer, the older the rock is.
Looking at the layers alone, we can say that D is the oldest, and C would be next, so on and so forth.
The law of cross - cutt ing relationships, on the other hand, states that a geologic event, like a fault, is younger than the layer that it goes through.
So if we look at the figure given, the fault goes through all the layers, so we can say that it is younger than all the layers.

Answer: Mendel would have concluded that one pair of factors (genes) is responsible for two different characters in plants.
Explanation:
The 9:3:3:1 ratio observed by Mendel helped him to form his <em>Law of Independent Assortment </em>which states that the inheritance of one pair of factors (genes) is independent of the inheritance of the other pair.
Also from his previous studies, he obtained a 3:1 ratio for a single gene expression, flower color, which enabled to form <em> the Law of Segregation</em>, which states individuals possess two alleles and a parent passes only one allele to his/her offspring.
However, if he had observed a 3:1 ratio for two traits, he would have concluded that inheritance of characters occurs in pairs i.e., that a pair of alleles is responsible for two different characters in plants.

Answer:
C. Point mutations
Explanation:
Point mutation involves the insertion or deletion of a base pair or the substitution of a single base for another in a gene. Point mutation rarely cause a significant change in a gene.
<em>Gene duplication involves the repetition of a gene-containing DNA region in an organism. It can result from errors in DNA replication/repair and other circumstances in the cell.</em>
<em>Horizontal gene transmission involves the transmission of gene-carrying DNA materials between different genomes of different species of organisms.</em>
<em>Transposable elements are regions of DNA that have the ability to move from one place to another within the same genome. They often create a kind of mutation and change the genetic identities of cells. </em>
The correct option is C.
