Answer:
Humans are higher eukaryotic organisms, which give birth to live young. They show internal fertilization and internal development of fetus (inside the body of female). Fertilization takes place near the fallopian tube, present in the female body, during which male gamete (sperm) fuses with female gamete (egg) to form zygote. The zygote gets attached to the uterine wall, where it develops into embryo, and later on, into fetus. The fetus lives in uterus and gets nutrition from mother until birth. Thus, in humans, 'internal fertilization and internal development' are most typical methods before birth.
Explanation:
When you're auscultating the heart and you want to osculate on the left side, there are 3 different valves you can hear.
The first is the Pulmonary valve at the 2nd intercostal space
the next is the Tricuspid valve at the 4 intercostal space, right by the sternum.
The final is the Mitral valve at the 5th intercostal space, 1cm medially to the midclavicular line.
