Yes, even that somtimes some of them looks like trying to be suicide, like dolphins for example.

Instinct. Natural instinct: Example: A foal learning to stand within minutes of being born.
all animals hve a b asic survival instict ie not trying to attack something 30 or 40 times their size in the same way that a lightly built human would not attack a 200lb American football player. its basic instinct.
There is no real way to swallow really. It is more like an instinct that is built into the body.
An igloo assumes humans: there is no native population on the Antarctic continent. Any igloo built there was built as a survival shelter by humans probably learning how to build them for survival.
a God-given, built-in knowledge that animals posses at birth ---------------------------------------------- It's something you do without being taught. An instict is a response to a stimulus that is inborn and that an animal performs correctly the first time.
They test cosmetics on animals because since the animal is less important than the actual human, and they are similarly built like us, they test cosmetics and other products on them to see if it is safe for human use. It is also cheaper to get animals and test them, than to get human beings and test products on them.
Human beings have adapted to the extreme conditions of the poles by wearing appropriate clothing like insulated layers and using specialized gear such as snowshoes and skis for mobility. They have also built insulated shelters and use heating sources to stay warm. Additionally, humans have developed specific skills for survival in polar regions, such as ice fishing and hunting techniques.
Igloos can be built for survival on the continent. There are no permanent igloos there. Yes, during survival school, one sleeps overnight in a newly-built igloo.
Most of the time horses walk in about 5 mins. after it's born.
Most use .22 Long Rifle cartridges. Howver, some built for the US Military used a .22 Hornet centerfire, which fired a jacketed softpoint bullet. This was large enough to be used to shoot deer and similar animals in a survival setting.
Behaviours that come "built-in" are called instincts.
