Answer:
War, like any other crisis, has its obvious, although more superficial, and its subtler, but more profund, effects upon the family. Among the more observable effects of war on the family are the withdrawal of Young men from civilian, and their entrance into military, life, with a consequent increase in socially disapproved forms of behavior; the entrance of women into industry to replace the men drawn into the armed forces, with an accompanying neglect of small children and an increase in juvenile delinquency; and changes in marriage, divorce, and birth rates. The more profound effects of the war upon the family include intensification of the trend roward the companionship type of family; a further rise in the status of women; further losses of family function, with the increasing use of nursery schools for the rearing of preschool-age children and the extension of governmental provision for family security; further liberalization of the code of sexual morality; and an increase in family instability as an accompaniment of the transition from the institutional to the companionship type of family.

Explanation:
Amphibian's heart has 2 accessory chambers, Sinus Venosus (receiving blood) and Conus Arteriosus (sending blood out). Human heart does not have that chambers. Blood enters to the right auricle and then is pumped out by two ventricles.
Submarines (especially U-boats) played a important role in developing undersea operations as well as changing naval warfare. Gone are the days where all enemies can see each other eye to eye. The development of submarines especially in world war I allowed for submarines to stay longer, take the pressure of water better, and attack enemies better. Torpedoes also got an update that allowed them to shoot straighter, and smaller so that more can be loaded.
However, that is not too say, that u-boats are the only ones that benefited. In a way, ships and planes also developed. The development of Sonar allowed planes to spot submarines and bomb them, as well as for ships to drop depth charges or avoid submarines all together. Ships also were given disruptive camo-patterns that allowed them to have a higher chance of surviving even without weapons loaded on board.
While U-boats during World War I was fairly limited in what they were able to do, they paved the way to a whole new military branch, and changed the dynamics of war in the sea.
