A person whose red blood cells agglutinate with anti-B antibodies BUT NOT anti-A antibodies is type AB.
<h3>What is an agglutinate?</h3>
Agglutination is the process by which specific antibodies to antigenic components on the surface of red blood cells or inert particles (direct agglutination) or to antigenic components adsorbed or chemically attached to red blood cells or inert particles produce clumps of cells or inert particles (passive hemagglutination and passive agglutination, respectively).
When antibodies on one RBC attach to the antigen on another RBC, a process known as agglutination, globular to amorphous, grape-like aggregates of RBCs are formed. RBC agglutination supports immune-mediated hemolytic anemia when it is present (IMHA). The majority of IMHA instances do not exhibit agglutination, but when it does, immunoglobulin M (IgM) is the most frequently implicated because of its pentavalent nature. Agglutination, however, might be brought on by a very thick IgG antibody coating of the RBC membranes. Agglutination is typically regarded as IMHA's diagnostic sign.

A translocation that moves a gene from an area of euchromatin to heterochromatin would typically cause a(n) reduction in the expression of the gene.
<h3>What is euchromatin?</h3>
- A kind of chromatin that is sparsely packed, enriched in genes, and frequently engaged in transcription is called euchromatin.
- Contrasting with heterochromatin, which is compact and less accessible for transcription, is euchromatin.
- The human genome has 92% euchromatic DNA.
<h3>What is heterochromatin?</h3>
- Heterochromatin, often known as condensed DNA or densely packed DNA, has many different types.
- Between constitutive heterochromatin and facultative heterochromatin, these variations fall on a spectrum. Both contribute to how genes are expressed.
- Eukaryotic genomes contain heterochromatin, which serves a variety of purposes including regulating gene expression and preventing DNA replication and repair.

Answer: B. Individuals and agriculture
Explanation:
Given what we know, we can confirm that the scandal committed by the Secretary of the Interior who worked under President Taft was that he sold Alaskan coal lands that were supposed to be national parks.
<h3>Why is this important?</h3>
National parks are the way in which the government can preserve lands and protect the conservation of the organisms that inhabit those lands. The selling of these lands marked a major scandal at the time as they were considered shady dealings, shrouded in secrecy, that undermine conservative efforts.
Therefore, we can confirm that the answer is C, as he sold the Alaskan coal lands that were supposed to be protected national parks.
