Initially address, Gram-negative in light of the fact that the precious stone violet restrains the development of gram-positive.
Second question, Fermentation: the blend of carb lactose, bile salts, and pH turn it unbiased red since they are enteric and age lactose
Third, we would see the development since it is gram negative microbes.
Fourth
1. coliform microbes (pink settlements in light of the fact that the pH is brought down and they are lactose fermenters)
2. Looseness of the bowels typhoid, and paratyphoid bacilli (tan and straightforward provinces since they are non-fermenters)
The correct option is C.
Roundworm belongs to the kingdom animalia and to the phylum nematoda. It has round, unsegmented, smooth and thin body which can grow to the maximum of four feet in length. It has a bilateral symmetry. A roundworm has no skeleton and it reproduces sexually.
A.) The cell prepares for cell division.
Answer:
Why are molecules such as valinomycin effective at transporting ions across the membrane?
Valinomycin is effective as transporting ions across the membrane because it is no charged, so it can carry ions.
Why would a drop in temperature to or below the transition temperature limit valinomycin mediated K+ transport across the plasma membrane?
Valinomycin is limited by temperature because its activity is highly sensitive and it depends on a stable and an average temperature.
Explanation:
Valinomycin is effective at transporting ion across the membrane because is an antibiotic that alternates hydroxy and amino acid, ans it helps membranes to be permeable. Valinomycin is a cyclic molecule that helps in ions transportation through membranes. Also, antibiotics have a temperature range of activity, that's why it is sensitive to changes.
