Ionic bonds are between metals and are permanent and very strong. They could hardly be called an attraction. This happens when one atom steals another atoms electron. Covalent bonds are strong but occurs between two different atoms they are also permanent to in this bond they share electrons and not take away. Hydrogen bonds are temporary and occur between molecules that have hydrogen and molecules that have elements like oxygen which become attracted to the hydrogen. These are weak but when they build up they can become very strong.
Answer:
False
Explanation:
IF this were true this would jeopardize internal environment of our cells, similar to how not every key opens a key lock, not every molecule has the "key" to enter the intracellular and extracellular fluids through a phospholipid bilayer. Usually small hydrophobic ("water-hating") can pass through the intracellular and extracellular fluids through a phospholipid bilayer.

3. Histamine is released
4. White blood cells travel to the invaded area

Answer:
too much nitrogen in surface runoff can cause algae to overgrow
Nitrogen fertilizers used in large-scale agriculture could leave a legacy of pollution that would persist for decades in soil and groundwater, scientists in France and Canada warned, which published a study in the National Academy of Sciences magazine, " PNAS ". According to these scientists, the excess of these fertilizers in the environment has been linked to contaminated drinking water and can cause the rapid growth of algae that compromise aquatic ecosystems and coastal marine life.
