Answer:
The skin
Digestive tract
Vagina
Mucous membrane
Explanation:
The skin prevents microbes from entering the body

Answer:
To look at the stars in the sky, your head is in the backward position.
Explanation:
To look at the stars in the sky it is necessary for the individual to project his face upwards, throwing his head completely backwards. This movement promotes the extension of the cervical spine, which allows the occipital approach to the C7 vertebra. This allows us to call the position of the head "backward", since to look upwards, the head needs to assume this position.
