Answer: Birds pick up oil on their beaks, by rubbing against the uropygial or preen gland near the tail, and then rub it over their feathers. This makes the water unable to break through the oil.

Explanation: Hope this helps have a great day :)

Answer:

Feathers repel water because birds pick up oil on their beaks and when they fluff their feathers later the oil is transferred onto the feathers. As water cannot penetrate through the oil coating, the feather is waterprof.

Answer:

Glycocalyx

Explanation:

Most of the eukaryotic cells have a coating outside their cell membrane. This coating is called the glycocalyx. It consists of glycoproteins and glycolipids. The sugar parts of these compounds are in contact with the underlying plasma membrane.  The function of the glycocalyx is to protect the cell. Certain specific molecules of the glycocalyx are involved in the recognition of cells so that they can recognize one another to make contact.

_______ 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!
