Answer 1

Answer: (A), (C), (D)

The correct options are
A Placenta provides nutrition to the embryo.
C Cervix is the connecting link between the uterus and vagina.
D At the foetal stage, body parts can be identified distinctively.

$\bullet$ Placenta is a disc-like tissue embedded in the uterine wall. It contains villi which serve primarily to increase the surface area by which products from the maternal blood such as oxygen and glucose are made available to the growing embryo.
$\bullet$ Around every month, females release a single egg from either of their ovaries. The inner lining of the uterus prepares itself for bearing a zygote in case the fertilisation occurs. Incase zygote is not formed, the inner lining of uterus breaks and sheds through the vagina. This is called menstruation or vaginal bleeding period.
$\bullet$ Cervix is the lowermost portion of the uterus that connects the uterus to the vagina.
$\bullet$ When the embryo develops all the body parts like hands, legs, head, eyes, etc., in the mother's uterus, it is known as a foetus.
