Answer:
When an E.coli cell is infected by multiple phages,they will take either lytic or lysogenic pathway.
Explanation:
When lambda phage bacteriophage infects an E.coli,it can either undergo lytic cell growth and lyse the host cell or enter lysogenic pathway.
The operator region of lac operon in E.coli contain single repressor binding site whereas the lambda operators  and
 and  each contains 3 repressor binding sites (
  each contains 3 repressor binding sites ( and
 and  )  that are differently occupied under different conditions.
)  that are differently occupied under different conditions.
The differential affinity of lambda repressor for the three binding sites in these operators play an important role in the maintenance of lysogenic state of lambda prophage in E.coli.
The lytic development occurs in cells infected with lambda phage that carry   gene.
 gene.
In contrast,lysogeny will occur in bacteria that infected with lambda phage that harbor a deletion of Cro gene.

Answer;
Husk.
Whole-grain flour contains all parts of the grain with the exception of the husk.
Explanation; 
Whole grain foods contains the following parts; Bran, Endosperm and Germ, originally present before processing.
Refined grains on the other hand are mainly  composed of only endosperm portion of the grain. Milling process removes bran and some also removes germ, along with the majority of fiber, vitamins, minerals, antioxidants and phytochemicals.
