Biome is characterized by low annual rainfall, less than 26 centimeters (about 10-11 inches) per year it is the Desert it rains less than 25 cm each year.
A biome is a region or area, land that is featured by the flora, fauna and environmental condition of that region.
Thus, it is the Desert it rains less than 25 cm each year.

b. The corepressor will not be able to interact with the operator and will cause an increase in the production of toxin.
c. The repressor will not be active, therefore toxin production will decrease.
d. Without the compressor to interact with the operator, the repressor will stay bound to the promoter leading to a decrease in the amount of toxin.
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:
Cell membrane is also called as semi permeable membrane.
Explanation:
It allows some chemical compounds to pass through and stops the other from their entry.
B. midpiece
C. tail
D. nucleus
The answer would be B) midpiece
b. incomplete dominance.
c. codominance.
d. complete dominance.
I would say the answer is: Co-dominance
When I was taking biology I learned that there are 3 types of alleles.
You have IA, IB, and little i. The little i means it is a recessive trait. IA and IB are co-dominant. There's a lot more gibberish language I could use.
Good luck and hopefully this helped. If you need me to go into greater detail just let me know.
