What is the relationship of the amniotic sac and the umbilical cord to the developing embryo?
The amniotic sac, filled with amniotic fluid, surrounds and protects the developing embryo, providing a cushioned environment that facilitates movement and helps regulate temperature. The umbilical cord connects the embryo to the placenta, serving as a vital conduit for nutrients, oxygen, and waste removal between the mother and the developing fetus. Together, they support the embryo's growth and development throughout pregnancy.
Eggs that cushion the embryo in fluid and protect it with membranes and a shell developed first in?
Reptiles were the first group whose eggs cushioned the embryo in fluid and protected it with membranes and a shell. This prevents eggs from drying out and allows them to be laid away from water.
How does the protein control the sex of a developing embryo?

What are three ways that embryo's are protected in sexually reproducing organisms?
Embryos are protected by the physical structures of the reproductive system, such as the uterus in mammals. Embryos are protected by the presence of amniotic fluid or egg membranes that surround and cushion the developing embryo. Embryos are protected by parental care, such as brooding behaviors in birds or the provision of nutrients and a safe environment in mammals.
What is the function of the endosperm?
to provide nourishment to the developing embryo in a seed
What protects and nourish the developing embryo?
The developing embryo is protected and nourished by the amniotic sac, which contains amniotic fluid that cushions the embryo and provides a stable environment. The placenta plays a crucial role by facilitating the exchange of nutrients, gases, and waste between the mother and the embryo, while also producing hormones that support pregnancy. The umbilical cord connects the embryo to the placenta, ensuring a continuous supply of essential substances. Together, these structures ensure the embryo's growth and development throughout gestation.
How is a fish embryo protected?
