Tenements were the houses built for the immigrants that arrived US during 1840 and 1850. Tenements are the urban dwellings but it does not meet the standard of a good sanitary life or poor sanitation.
Explanation:
Impoverished and undernourished families live in testaments. They are apartment house which fail to meet the sanitary standards, safety and comfort too. Trash piled up and garbage littered on the streets, poor sewage system also contribute to the spread of hazardous and contagious diseases.
Air quality also proves to be terrible. there was lack of fresh running water. Tenements housed more than one family in the same apartment. Unsanitary conditions always prevail which is not good for health. These were the housing facilities offered to immigrants until the implementation of new deal Programs.

A is my best answer . because it says some it could be the customer because it says costumers.
The president would be interviewed by Congress and a hearing would be made to impeach the president, just because the president is impeached doesn't mean he's kicked out
16. A Couple with the ability to taste PTC have two grown sons and one grown daughter. The sons have the ability to taste PTC. Their daughter is a PTC non-taster. She married with a PTC non-taster man and have two sons.
The ability to taste Phenylthiocarbamide<span> or PTC is inherited by autosomal dominant trait. The daughter of the first generation should be autosomal recessive(tt) as she was a non-taster. That means her parent would be heterozygotes(Tt) since they have the ability to taste PTC. Her brother could be homozygote dominant(TT) or heterozygote(Tt). The pedigree would be:
i. no-shade square(Tt) -----------------</span>no-shade circle(<span>Tt)
ii. </span>no-shade square(T?), no-shade square(T?), shaded circle(tt)------shaded square(tt)
iii. shaded square(tt) and shade square(tt),
17. She marries with non-taster too which means also a homozygote recessive. Since both parents are homozygote recessive, the children should be 100% homozygote recessive too.
The phenotype of the sons in generation III would be 100% non-taster.
18. The genotype of the female should be XX. To express the recessive trait, an individual need to have all recessive genes. If she has a recessive trait of an X-linked disease then both of the X genes should have a lowercase letter(recessive).

19. The genotype of a male should be XY. If he has a recessive trait of an X-linked disease then the X genes should have a lowercase letter(recessive). As there is only one X gene in male, to express recessive he only needs 1 recessive gene.
