3. at Morula stage, 7th - 8th day post fertilization
4. at Blastocyst stage, 7th - 8th day post fertilization
The duct of seminal vesicle opens into the:
1. Caput Epididymis
2. Cauda Epididymis

Identify the human development stage shown below as well as the related right place of its occurrence in a normal pregnant woman, and select the right option for the two together:
Developmental stage | Site of occurrence | |
1. | Blastula | End part of fallopian tube |
2. | Blastocyst | Uterine wall |
3. | 8-celled morula | Starting point of fallopian tube |
4. | Late morula | Middle part of fallopian tube |
In a human female, the blastocyst:
1. | gets implanted into uterus three days after ovulation |
2. | gets nutrition from uterine endometrial secretion only after implantation |

4. Male accessory glands
What happens during fertilisation in humans after many sperms reach close to the ovum?
1. | Only two sperms nearest the ovum penetrate zona pellucida |
2. | Secretions of acrosome help one sperm enter the cytoplasm of the ovum through zona pellucida |
3. | All sperms except the one nearest to the ovum lose their tails |
4. | Cells of corona radiata trap all the sperms except one |
