Answer:

Genetic drift

Explanation:

Genetic drift is an evolutionary mechanism that in a population it changes allelic frequencies over generations just by chance. For this reason, small populations are more susceptible to be affected by genetic drift than bigger populations.  

In this example, Indiana Jones visited a small village of 50 people and over generations allele A probably was lost just by chance, or by genetic drift.

Setler [38]

Answer:HOPE THIS HELPS :D

Explanation:

For coronavirus, it spreads when a person with coronavirus coughs, sneezes, get his or her saliva on another person, or when they get discharge from their nose on another person. I also know that if an infected person infects a non living object, the next person that touches it can get coronavirus by touching his or her body part. (Basically any where with holes including eyes, nose, mouth etc.)  coronavirus can stay on surfaces for a long time. I don’t know how long though.

9. a) How does hydrogen bonding help the transport of water in plants?
grigory [225]

Answer:

Water has a high Cohesion because of Hydrogen bonding. This is important as transport of water in the Xylem in plants relies on water being pulled up. Cohesion also gives the water a high surface tension, allowing small organisms, such as Pond Skaters, to walk along it.

Explanation:

Water molecules forming hydrogen bonds with one another. The partial negative charge on the O of one molecule can form a hydrogen bond with the partial positive charge on the hydrogens of other molecules. Water molecules are also attracted to other polar molecules and to ions.

Plants obtain the hydrogen they need from water molecules. Don't try to feed your plant hydrogen gas -- your plant wouldn't know what to do with it if you did. As long as they have water, plants can readily obtain all the hydrogen they need. :)
