Fossil A is older than Fossil B

Answer:

Fossil A is older than Fossil B

Explanation:

The oldest fossils are those found in deeper layers. This is because sedimentation is a sequential process that increases the original ground level. Thus, the soils in the most superficial layers have suffered less sedimentation impacts, because they are younger.

Fossils are records of living things that existed in the past and were somehow preserved. These living things may be preserved in rocks, sand, ice and, believe me, even within another fossil. Dinosaurs are the big stars when we talk about fossils. Who has never dreamed of discovering a large dinosaur skeleton?

Positioning this victim like this will prevent the risk of causing further injury.

Which evolutionary mechanism changes genotype frequencies but does not change allele frequencies?
Montano1993 [528]

Assortative mating is the evolutionary mechanism that changes genotype frequencies but does not change allele frequencies.

Assortative mating is the type where two individuals mate with each other on the basis of their similarities and dissimilarities. This is a different phenomenon than the random mating that occurs by chance. Assortative mating can be used to increase the number of organisms of a population containing a certain trait.

Allele is the alternative form of a gene. It arises due to mutations. A gene can have more than one types of alleles. However, usually a gene only has one allele. The alleles are found at the same location of the homologous chromosomes.
