Beneficial mutations are more frequently fixed in large populations than in small ones, whereas deleterious mutations are more frequently eliminated.
Explanation:
Answer: Carbohydrates and lipids both contain carbon, hydrogen, and oxygen
atoms, while the proteins contain nitrogen in addition to those three
elements
Explanation:
Algae growth and oxygen depletion in lakes and stream, and methemoglobinemia, caused by too much nitrate-nitrogen in drinking water.
Answer:
C) polarity
Explanation:
The polar nature of water molecules allows it to dissolve like molecules, such molecules are also polar.
- In water molecules hydrogen bonds provides a special dipole - dipole attraction.
- Here, the hydrogen atom is directly joined to a highly electronegative atom(oxygen, nitrogen or fluorine).
- This leads to a charge separation in which the hydrogen atom has net positive charge and the electronegative one has negative charge.
- This makes the molecule of water polar.
- By this property water easily attracts oppositely charged portions of another substance and then pull them into solution.
This property of water is polarity of water.
Complex.
