These 10 animal facts will amaze you. A polar solvent is a liquid with molecules that have a slight electrical charge due to its shape. For example, water is a molecule with one oxygen and two hydrogen atoms.The two hydrogen atoms are not on opposite sides of the oxygen, but rather at an angle.hese 10 animal facts will amaze you.

1. an example of selective breeding is crossing a poodle and a labor-doodle that have desired traits. usually this is practiced on by plants and animals.
Fitness traits are especially at risk with this breeding scheme. Selective breeding through controlled mating enables farmers to breed animals that are more resistant to the impacts of climate change, such as sudden changes in temperature, prolonged droughts or the appearance of new diseases.owever, in general controlled breeding is a low-cost technology. If stones are locally available and can be used to build the mating pens, an average investment would come to around US$ 30. In areas with clay soils, adobe bricks may be used, at an average cost of US$ 90.
