the person's environment and social interaction
the person's genetics and environment
the person's gender and age
the person's salt intake and stress level

B .person's genetic and environment

Explanation:

(i just took the test)

Genetics plays a large role. After advancing age, the greatest risk factor for developing Alzheimer's is having a family history of it. If you have a parent, sibling, or even child with the disease, you're more likely to get it. This risk rises with each family member who has it. Genes do play a role in Alzheimer's disease. The gene with the strongest influence on the development of Alzheimer's is called APOE-e4 (short for apolipoprotein E-e4). Scientists believe up to one-quarter of all Alzheimer's cases are due to this gene.

Explanation:

micro/nanoscale topography surface exhibits many prominent properties and is extensively employed in biomedical device, microfluidic device and energy device fabrication. additionally, the clinical applications of biomaterials can be largely expanded with of nanostructured surfaces.

an organism's phenotype is the  form of a trait  that it  displays. for  flowercolor, a pea  plant  can  display  a phenotype of purple or white flowers. an organism's  genotype  is the alleles of a gene it contains. based on his data, mendel concluded that a phenotype can be  determined  by more than one  genotype.
