Answer:
If larger seed became available, directional selection will act in favor of bigger beak finch.
Explanation:
In the case that more large seeds were to become available, then directional selection will start to influence in the beak size, favoring those individuals with bigger beaks. Those individuals with shorter beaks will start to disappear as these animals won't be able to eat the larger seed.
Directional selection <em>increases the proportion of individuals with an extreme phenotypic trait,</em> in this case, large beaks.
This selection presents more frequently in those cases in which <em>interactions between living organisms and the environment</em> modify in the same direction.

Explanation:viruses are small non-living particles that contains hereditary materials.viruses attack cells of other organisms such as plants , bacteria ,archaea etc.
Viruses are acellular and contains either DNA or RNA.they cannot synthesis protein as they lack ribosomes ,so they use the ribosomes of the cell they have invaded to synthesize they proteins they need.
A virus usually has a central core surrounded by an outer protein coat called capsid.
Viruses can reproduce only within the living host cells and they are specific to the type of cells they attack.they attack plants through insect vectors or through openings on the plants.
Viruses can affect bacteria by injecting their nucleic acids through the cell wall and into the bacteria cell.such viruses are called bacteriophages.
