The molecule of water is decribed as a polar molecule

Biology
1 answer:
Mila [183]3 years ago
6 0

Polarity of a Water Molecule. Water (H2O) is polar because of the bent shape of the molecule. The shape means most of the negative charge from the oxygen on side of the molecule and the positive charge of the hydrogen atoms is on the other side of the molecule. This is an example of polar covalent chemical bonding.

  • It divides the innermost layer from a layer of smooth muscle tissue.
  • it is a light red layer barrier located between the white lumen and blue lamina.
  • It is made up of epithelium cells.
  • It is also found in the respiratory tract, the Gastrointestinal tract, and the urogenital tract.

Thus, the light red layer between the white lumen and blue lamina propria consist of epithelium cells.

_______ cause(s) populations to change over time.
vekshin1
The answer is B., Natural Selection.

Weather certainly doesn't change populations, and genes only caused individuals in a population to be slightly ( genetically-wise ) different from the others. It does cause change, but not change in the whole population over time.
Natural disasters don't change the populations over time either. Natural disasters only caused change in their environment, at most.

So, the only answer left is natural selection, and it makes sense too! 
Natural selection is the process where the individuals with better traits suited to survive in that specific environment live on and give those good traits to their offspring.
The individuals with less suited traits to survive will die out, and will not be given an opportunity to reproduce and pass on their less suited traits, so over time, the population will increase of individuals with better suited traits to survive and the individuals with less suited traits will eventually die out, therefore making the entire population change.

Hope I helped you!
