Ans - embryoblast .
Inner cellm is also called embryoblast or pluriblast.
Embryoblast is a part of the blastocyst. The blastocyst contains three layers ,the outer trophoblast layer , inner cell mass layer or embryoblast and the blastocoel . The embryoblast layer forms within the blastocyst before implantation within uterus . The embryoblast layer undergoes a process called gastrulation where the cells get organised into three layers of pluripotent cells which are the ectoderm , mesoderm and the endoderm. Thses cells give rise to the body parts in an embro . So embryoblast layer basically forms organs and body parts .
Zona pellucida , zona radiata are ace protective layers arpund ovum.
Acrosome is a part of sperm cell resemblws a cap like structure ,it helps the sperm to penetrate the ovum and fertilise the egg.
Placenta is an organ which connects the fetus to the mothers uterine wall , helos in nourishment .
If this helps please give it a positive rating. Thank you

Sodium hydrogen carbonate (NaHCO3) also known as sodium bicarbonate or "baking soda", can be used to relieve acid indigestion. Acid indigestion is the burning sensation you get in your stomach when it contains too much hydrochloric acid (HCI), which the stomach secretes to help digest food. Drinking a glass of water containing dissolved NaHCO, neutralizes excess HCl through this reaction: HCl(aq) NaHCO3(aq) NaCl(aq)+ H,O)+ Co,(0) 4 The CO, gas produced is what makes you burp after drinking the solution.

The mass of the symmetrical wheel shown below is m = 4 kg and its radius of gyration about its center is kg = 0.25 m. The outer radius of the wheel is r2 = 0.4 m. The radius of the inner hub, where a cable is wrapped around it, is rı = 0.2 m. The wheel rolls without slipping. The force P, applied to the cable, is increased slowly according to the linear relation P = at, where P...
