Derived from the inner cells of a human blastocysts , a very early human embryo.
At the blastocyst stage, five to 10 days after fertilization,
the embryo is a cluster of 100-200 cells

Answer:

All embryonic stem cells are undifferentiated cells that are unlike any specific adult cell.

Human embryonic stem cells are derived from in vitro fertilized embryos less than a week old

Embryonic stem cells are of great interest to medicine and science because of their ability to develop into virtually any other cell made by the human body.

Scientists have been attempting to isolate and culture human embryonic stem cells for more than a decade.

Human embryonic stem cells will offer insights into developmental events that cannot be studied directly in humans in utero or fully understood through the use of animal models

Match the reproductive structures based on their function and the system to which they belong.

Rashid [163]

Complete question: Find the complete question in the attached file below.

Answer: From the question, the system to which the structures belong are:

Female reproductive structures include: Egg, ovary, fallopian tube, vagina.

Male reproductive structures include: Urethra, sperm, testis, Vas deferens

Explanation:

The female reproductive system is made up of structures, listed above, which functions together with the purpose of reproducing offsprings. Below is the structure matched with the correct function from the question given:

--> Egg: This functions as the sex cell or gamete

--> ovary: The site where gamete are produced

--> Fallopian tube: This functions to transport the gamete from the site of production in the reproductive system

--> Vagina: connects the internal reproductive fluids to the exterior.

The male reproductive system are also made up of structures that functions together to bring about the fertilization of the female sex cell. Below is the structure matched with the correct function from the question given:

--> Urethra: connects the internal reproductive fluids to the exterior.

--> Sperm:This functions as the sex cell or gamete

--> Testis: The site where gamete are produced

--> Vas deferens: This functions to transport the gamete from the site of production in the reproductive system.
