Answer:
The placenta is the temporary association of fetus and maternal tissue. It is meant for nutrition and transport of different substances.
Explanation:
The placenta is a temporary association of fetal and maternal tissues. The placenta is formed from the trophoblast of the blastula. These trophoblasts form chorionic villi which later forms the placenta. The chorion and allantois also take part in the formation of the placenta. Hence, the human placenta is known as the chorioallantoic placenta. The process of formation of the placenta is known as placentation.
The placenta has several functions but the major function is to provide nutrition to the fetus. The developing fetus gets nutrition from the mother's body by the placenta. The placenta provided with blood vessels which help in the transportation of different substances. It also helps in gas exchange between the mother and baby. Thus it plays a vital role in fetal respiration. The metabolic wastes diffuse through the placenta. Placenta also stores fat, glycogen, which participates in protein metabolism.

Explanation:
None of the suspectswere responsible for the crime.Most of the Genome contains two versions of the marker as human is diploid.If any of the victims have committed the crime,the victim hair markers must match the suspect's markers.
From the gel we see clearly that suspicious hair markers do not match the markers of suspicious criminals. Instead, it matched the fragments of the victim's DNA(as lane 2 & 3 bands are the same). Suspicious hair is the hair of the suspect.
