Biology GK Quiz with Answers

The stapes or stirrup is a bone in the middle ear of humans and other animals which is involved in the conduction of sound vibrations to the inner ear. This bone is connected to the oval window by its annular ligament, which allows the footplate to transmit sound energy through the oval window into the inner ear.

Infant development begins at birth. Consider major infant development milestones from birth to 3 months — and know what to do when something's not right

The uterus is an inverted pear-shaped muscular part of the female reproductive system. It is positioned between the bladder and the rectum. Its function is to nourish and encloses a fertilized egg until the offspring, is ready to be delivered. It is within the uterus that the offspring develops during gestation. Once the egg has left the ovary it undergoes fertilization and implants itself in the lining of the uterus. The key function of the uterus is to provide nourishment to the developing fetus prior to birth. Thus, the baby is born as a result of rhythmic contraction of muscles in uterus.

Intracytoplasmic sperm injection (ICSI) is an infertility treatment. It involves injecting live sperm into a person's eggs in a laboratory. This procedure can create an embryo (fertilized egg). ICSI is a form of in vitro fertilization (IVF).

Fertilization is a process of fusion of gametes to form zygotes. A zygote is a single cell which is formed by the fusion of male and female gametes during sexual reproduction.

The sperms are formed in the testes and are transported through the vas deferens into the urethra. This urethral tube unites with a tube coming from the urinary bladder. The urethra thus forms a common passage for both the sperms and urine.

In the fallopian tube, the sperm meets the egg that was released from the ovary during ovulation.

The testes in humans are situated outside the abdominal cavity inside a pouch called scrotum.

Puberty is the process of physical maturation where an adolescent reaches sexual maturity and becomes capable of reproduction. On average, puberty typically begins between 8 and 13 in females and 9 and 14 in males.
