A because it’s not wasting more just soreading
True. Some bacterial cells are resistant to a variety of antimicrobials because they actively pump the drugs out of the cell.
A significant resistance mechanism in Gram-negative bacteria is drug efflux. It expel solutes from the cell. Antimicrobials and metabolites are just a few of the hazardous compounds that Efflux pumps help bacteria remove from their interior environments so they can regulate it.
The main efflux systems in Gram-negative bacteria are members of the RND superfamily and typically consist of an outer membrane protein channel, a periplasmic protein, and a cytoplasmic membrane pump. The most common example is MFS (such as Bmr and Blt in Bacillus subtilis) and the ABC transporters.

Answer: disrupts ability to fight disease
Explanation: Stress may disrupt homeostasis. Your heart may beat more rapidly or your breathing may increase because your stress, disrupting homeostasis.
Answer:
Incomplete Dominance
Explanation:
Incomplete dominance is a phenomenon in which the alleles of two genes are not completely dominant over each other and so when they are present at the same time in an organism (heterozygous for that gene) the organism will have an intermediate phenotype that is a combination of both phenotypes.
For example: The flower color in Snapdragon can have three different genotypes as well as phenotypes. The flowers can be red, pink or white depending on their genotype. The allele for red flower (R) is incompletely dominant over allele of white flower (r). A plant with genotype RR will be red flowered and that with rr will be white flowered. However, if a plant has genotype Rr (intermediate), then the flowers will be white in which no allele was dominant over the other and both showed their effect giving a combination of two colors as Pink flowers.
Same is the case with the mating between white and black hen, where offspring was grey in color. This grey was a combination phenotype of two phenotypes.
Hope it helps!
