<span>Since purple is dominant over white, it is fair to say that white is recessive. The crossing over of two white plants suggest that the parents are both homozygous recessive. Crossing over of 2 homozygous recessive white plants would produce progeny. In the production of 1000 offspring by two white plants, all of the1000 progeny would be white as well.</span>

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>
