Answers

Answer: yolk sac

explanation:

the placenta does not develop for a long time so the alternate way of supplying the developing embryo is through the yolk sac which the embryo can receive nutrients and respiratory gas exchange through which the placenta will be formed later.

Kangaroos are mammals that lack a placenta; therefore, they must have an alternate way of supplying the developing embryo with nutrients, as these should be passed from the mother to the embryo during the time of pregnancy.

What is the function of the placenta in pregnancy?

The placenta is an organ that develops during pregnancy to provide nourishment to the growing fetus and to remove waste products from the baby's blood and is attached to the wall of the uterus and connected to the baby by the umbilical cord, it is responsible for producing hormones that maintain the pregnancy, such as progesterone, which helps to keep the lining of the uterus thick, also produces human placental lactogen, which helps stimulate the mother's mammary glands to produce milk.

binary fission asexual reproduction in which a single cell divides into two with no exchange of genetic material; reproduction method of bacteria

budding A kind of asexual reproduction involving the growth of a new individual from part of an older organism. It can also refer to uneven distribution of cells that results in one cell receiving most of cell contents. In grafting, budding involves reducing the scion to a singular bud.

central disk =  The central portion of a starfish. The arms of a starfish radiate from the central disk.

colony = A group of organisms attached to one another after undergoing asexual  reproduction from a common parent.

conidia = A special kind of asexual spore found in many kinds of fungi.

multiple fission = A kind of asexual reproduction in which a single cell undergoes many mitotic divisions in the nucleus and a number of daughter cells are produced all at once.

propagation = The act of propagating or establishing and growing new plants.

protist = A one- or few-celled organism with chromosomes. Many have characteristics of both animals and plants.

regeneration = A phenomenon in which organisms break into two or more parts and then each part grows into a new individual.

spore = A small, resistant cell that can grow into a new organism. They may be produced either by meiosis or mitosis.

unicellular = One-celled.
