nexus9112 [7]

Answer:

The probability of getting a dwarf and pink female is 1/2

Explanation:

In mice, dwarfism is caused by an X-linked recessive allele, and pink coat is caused by an autosomal dominant allele where coats are normally brownish.

A dwarf female from a pure line will have Xd Xd where d represent the  recessive trait and the female is also brownish (pp).

A pink male from a pure line will be XPY where P represent the dominant allele but not a dwarf (D).

IrinaVladis [17]

Answer: Option C) blocks oxygen transport in human blood

Explanation:

Carbon monoxide (CO) is one of the oxides of carbon formed when fuel is incompletely burned. It can be generated from exhaust pipe of vehicles, electric generators.

When inhaled CO attaches to the hemoglobin portion of the red blood cells, forming a bound complex called CARBOXY-HEMOGLOBIN, that is unable to transport oxygen to the body tissues.

Thus, by this mechanism Carbon monoxide blocks oxygen transport in human blood
