Polar bears are animals that live in cold environments.
Their environment should be a place conducive for breeding and propagating
their species. If ice caps are melting and the length of the cold season is
declining because of the effects of climate change, polar bears will have less
time hunting for food.
Generally, the coldest season is the best hunting
time for polar bears. It is easier to catch seals and fish due to the thickness
of the ice and the rise of water in their environment. This time to hunt is
enough to restore the polar bears’ body fat and fitness in preparation for the
warm season where there is less ice and food.
<span>As the warm season lengthens, the condition of
the polar bears’ bodies decline resulting to effects that are serious for pregnant
polar bears who are nursing and cubs who need their mothers’ energies to
survive the harsh environment. </span>
Ken and Kendra share 50% of their genes. Lara an Lonnie share 100% of their genes.
The fraternal twins are just siblings that share the same womb. Each of them starts it's development as separate egg that is fertilized by a separate sperm, so they are no more similar than the other siblings.
The biological (identical) twins, on the other hand, come from the same fertilized egg, thus they share the same genes.
Answer: The testing effect
Explanation:
The testing effect can be generally used to find out that long-term memory is generally increased when a bit of the (adapting)learning period is spend towards retrieving what is to be retained in the brain.
This effect is often referred as practice testing or retrieval practice. This is required to test what is retained in the brain which was studied over a long time back.
This effect is known as the testing effect.
