Answer 1

Answer:

Correct option is:

b) zona pellucida

The new membrane formed by follicular cells in secondary oocyte is called zona pellucida.

Explanation:

The new membrane formed by follicular cells in secondary oocyte is called zona pellucida. The Zona pellucida, also known as an egg coat or a glycoprotein layer that surrounds the plasma membrane of mammalian oocytes, is a glycoprotein layer that surrounds the plasma membrane of mammalian oocytes. From monotremes that lay eggs to placental mammals, the zona pellucida (ZP) is a relatively thick extracellular matrix (ECM) that surrounds all mammalian oocytes, eggs, and preimplantation embryos. The zona pellucida is a thick covering that develops on the secondary oocyte. Ovulation releases the oocyte from the Graafian follicle. In unilinear primary oocytes, the zona pellucida first appears. Both the oocyte and the ovarian follicles secrete it. The corona radiata surrounds the zona pellucida. The corona is made up of cells that look after the egg after it leaves the ovary.
