3 students per team

Like humans, rats are placental mammals. This means that , before birth, the fetus develops in the uterus and receives nourishment and oxygen from the mother through the umbilical cord. Rats are similar to humans; they are omnivores and have little body hair. They also have similar internal systems. Therefore, by dissecting a rat, you can directly observe the characteristic features and arrangements of mammalian systems.
