Answer:
The answer to the question: What effect will the decreased iron availability have on the production of diphteria toxin, would be, A: The lack of co-repressor binding to DtxR will lead to a loss of repression and an increase in the production of toxin.
Explanation:
Diphteria is a very serious disease that is caused by the gram-negative bacteria Corynebacterium Diphtheriae, which attacks the upper respiratory tract, especially the throat, and causes a thick lining to form, complicating the normal respiratory function. In order to accomplish such a feat, this bacteria produces a toxin that attacks human cells. But the toxin will not be produced if there is a high availability of iron in the area where the bacteria intends to infect, because if that is the case, then iron will work as a co-repressor with DtxR to prevent the expression of the bacterial gene that codes for the toxin. A co-repressor means that iron will work as a coadjuvant for DtxR and will not allow the genes of the bacteria to produce the toxin. In the case of this question, the answer is A because we have a lack of iron availability, which means that DtxR will not be enough to stop the toxin from being produced.
Answer:

II. Smooth
III. Striated
A. I only
B. II only
C. III only
D. I and II
E. II and III
2. Phenotype
3. Codominance
4. Heterozygous
Answer:
phenotype
Explanation:
phenotype is the physical properties of an organism
best regards!!
An organism's physical appearance is called its 2. Phenotype.
An organism's phenotype refers to its physical appearance or observable characteristics, such as its color, height, or shape. For example, if we are talking about flowers, the phenotype may include the color of the petals or the shape of the leaves.
These traits encompass physical attributes, behaviors, and other characteristics. Phenotypes can vary widely, even among individuals with the same genotype, due to factors like gene expression, environmental influences, and developmental processes. Phenotype plays a crucial role in understanding genetics, evolution, and the diversity of traits within a species.
