Answer:

A= stabilising selection, B= directional selection

Explanation:

A:

stabilising selection is any type of force that pushes the population towards a mean trait .

B:

Directional selection, or positive selection is a mode of natural selection in which an extreme phenotype is favoured over other phenotypes, causing the allele frequency to shift over time in the direction of that phenotype. So imagine in your graph for be there are two different phenotypes, this type of selections drives the preference of phenotype in one direction so you end up with more individuals with that specific phenotype.

Punnett square:

      R       R'

R'    RR'   R'R'

R'    RR'   R'R'

Answer:

Mohammed should now <u>lift</u> the print from the surface to preserve it

Explanation:

In order to preserve fingerprint evidence as required by crime laboratory policies and criminal justice systems, for which we have digital photography, casting material, and latent print lifts, that can be used as secondary evidence

The ridges on the cast and lift can be photographed to serve as an additional secondary evidence

The  processing of the latent print after photographing is dependent on the surface type and may include the creation of an impression on soap, paint, wax, clay or dust

Therefore, Mohammed used an enhancement technique that made a fingerprint visible on a lamp. He photographed the print. Mohammed should now <u>lift</u> the print from the surface to preserve it
