Begging is a way of asking for something to be given to you, in a humble, pleading kind of way. The dog in the picture is begging for food.
Beggars are people who have no way of getting money on their own, so they ask other people to give them money or goods. Beggars are often homeless. In many countries, beggars are sick, disabled or mentally unstable and beg because they cannot work.
Dregs is the residue left behind after something else has been taken away. Dregs usually refers to the poorest quality part of something that has been left behind, or the worst of something, as in "the dregs of society".
Birds, fish, most insects and most reptiles lay eggs, as do monotremes and amphibians. Birds lay eggs with a hard shell, and only one at a time, although they may lay several eggs to fill a nest. Reptiles like turtles and crocodiles lay eggs with leathery shells, and can lay hundreds of eggs at once. Fish and frogs lay eggs in the water, and most have no shells or a coating of jelly to make it hard for other things to eat them. Insects also lay eggs, and most are so small you can hardly see them. Only a very very small number of animals lay eggs. The platypus is one of them.
A keg is another name for a cask or barrel. Modern kegs tend to be made from metal, and contain drinks stored under pressure.
