Answer:
The correct answer will be- Bacteria were able to utilize the food material in nine containers by producing respective enzymes.
Explanation:
The process of utilization of food material as a source of food depends on the Operon machinery of the Bacteria. The Operons gets activated in the presence of the inducer molecule which leads to the gene expression and the production of the enzymes to digest the food substance.
In the given condition, since the bacterial growth was observed in the nine containers out of ten shows that bacteria expressed the genes and produces enzymes to digest the substance in nine plates only and showed growth.
Thus, Bacteria were able to utilize the food material in nine containers by producing respective enzymes is the correct answer.

C. All organisms have the same number of chromosomes.
D. A karyotype cannot determine if an organism is male or female.
Answer:
A karyotype cannot determine if an organism is male or female. Thus, the correct option is D.
<h3>
What is karyotype?</h3>
A person's entire set of chromosomes is known as their karyotype. The phrase can also refer to an image created in a lab showing a person's chromosomes separated from one cell and organized in numerical order. A karyotype can be used to check for chromosomal number or structural problems.
Males and females may have different karyotypes. For instance, human females have two X chromosomes while males have an X and a Y chromosome in their karyotype. Body (somatic) cells and egg and sperm cells have different karyotypes (gametes).
