• B)negative regulatory effects of a large number of different bacteriophage proteins produced soon after infection.
• C)positive regulatory effects of a small number of different bacteriophage proteins produced soon after infection.
• D)negative regulatory effects of a small number of different bacteriophage proteins produced soon after infection.
• E)positive and negative regulatory effects of a small number of different bacteriophage proteins produced soon after infection.

Definitions:

Chloroplasts

Organelles found in the cells of green plants and photosynthetic algae that conduct photosynthesis by capturing light energy to synthesize carbohydrates.

Underground Stem

A stem of a plant that grows beneath the surface of the soil which can store food or be reproductive, examples include rhizomes and tubers.

Modified Leaves

Leaves that have undergone changes to perform specialized functions beyond photosynthesis, such as tendrils for climbing or spines for protection.

Circumference

Circumference is the linear distance around the edge of a circle or circular object.
