They usually lay 2 eggs each breeding season and take turns sitting on this pair of eggs to keep them warm and safe from predators. When food is short, only one of the two chicks may survive.
Mostly rocks and twigs that the male finds from different places, they have to look out for other Adelie penguins, because they steal each other's pebbles and twigs. Your Welcome :)
Penguin calls (vocalizations) are individually identifiable, allowing mates to recognize each other and also their chick. This is important because members of a large colony of penguins are nearly indistinguishable by sight
No. All penguins are sea birds and they make their homes in sea water where they can find food. Four types of penguins do, however, breed on Antarctica's beaches for a few weeks each year: Emperor, Adelie, Gentoo and Chinstrap.
in cells and genetics
The most common number is '2' but in rare cases 3 or even 4 cubs are born in one litter.

Of course - with their own mates, but not with each other.
Penguins give their mates pebbles as a part of their courtship behavior. It is a way for them to bond and establish trust with their partner. The act of offering pebbles may also be a way for the male penguin to showcase his ability to provide and care for his mate.
Most penguins do. An emperor penguin will find it's mate, or "soulmate". Then they stay together forever, if one dies the other penguin will never mate with another penguin. They only will want that penguin.
Penguins show affection by offering pebbles to their mates as a gift, symbolizing their bond and commitment to each other.
For food,space,dominance,mates,and for territory!
Normally, unless mating or competing for mates, they ignore each other totally.
