What do Antarctica penguins do daily?
Two species of penguins breed on the Antarctic continent: Adelie and Emperor. They live at sea, because they are sea birds. During the breeding season, adult penguins tend eggs, keeping them warm in the extreme cold. Once the eggs hatch, one adult returns to the sea to feed. This adult returns with a full belly and regurgitates food into the mouth of the chick. The other adult, then, is free to return to the sea and feed. Once the chicks fledge, all penguins return to the sea.
What are the challenges of a emperor penguin?

Climate change and fishing has made it more difficult for them to find food. Humans also disturb their colonies.

Suggest how huddling helps the penguins to keep warm in extreme cold?
The penguins each take turns to go in the middle of the 'waddling circle' so that the circle of penguins around them warm the middle one with their body heat.
is often a more severe form of defense mechanism than the others and in its most extreme form can develop into amnesia?
Repression is a defense mechanism where unpleasant thoughts and memories are pushed into the unconscious mind. In extreme cases, repression can lead to the loss of memory, known as amnesia. This can be a maladaptive coping strategy if it prevents individuals from facing and processing difficult emotions.
What are some examples of animals that have adapted to extreme temperature?
Polar-bears and walruses are two examples of animals that have adapted to extreme cold temperatures. There are others - arctic fox, various species of penguins, etc. Camels are an example of adaptation to extreme (desert) heat - though in Siberia, they also have to adapt to cold.
Is bacterial endosporulation a reproductive mechanism?
No. Endosporulation is the process where bacteria encapsulates itself within an endospore - it's a form of protection against an extreme range environmental stressors. Sporulation on the other hand is the act of producing spores of the bacteria, and that IS a reproductive mechanism.
