Explain why DNA has an overall negative charge.

Answers

The ovaries are located in the ___ cavity.

Answers

The pelvic cavity contains the reproductive organs, urinary bladder, colon and rectum. Pelvic cavity is formed or bounded by three bone pairs called ilium, pubis and ischium.

Final answer:

The ovaries, important in egg and hormone production, are located in the pelvic cavity within the female reproductive system.

Explanation:

The ovaries are located in the pelvic cavity.

These are part of the female reproductive system and play a crucial role in both the production of eggs and hormones such as estrogen. They are held in place within the abdominal cavity by a system of ligaments. Further, the ovaries consist of a medulla and cortex: the medulla contains nerves and blood vessels to supply the cortex with nutrients and remove waste. The cortex, meanwhile, consists of follicular cells that surround eggs developing during fetal development in utero. During a menstrual period, a group of these follicular cells matures, preparing the eggs for release at ovulation.
