V125BC [204]

Answer:

Increase

Explanation:

Oligomeric enzyme have more than one polypeptide chain and the enzyme show positive cooperativity. It means that binding of the ligand to the enzyme will help other ligands to bind to the enzyme. Hill cofficient is used to measure the determining the degree of cooperativity of the binding between enzyme and substrate or ligand. As in this case, allosteric enzyme show positive cooperativity, its Hill cofficient will increase

Why was it profitable for General Motors and Ford to integrate backward into component-parts manufacturing in the past, and why
Fynjy0 [20]

Answer:

Why was it profitable?

(1) To control the quality of their spare parts.

(2) To reduce cost.

Why do they buy more parts outside?

(1) Inefficient in-house parts manufacturing.

The cost of managing Internal

(2) manufacturing of Automobile parts has increased.

Explanation: General motor and Ford are both world class Automobile manufacturers with several vehicles in every part of the world, General motors have its assembly plant in about 120 countries of the World.

During the early 20th Century they found that the local suppliers were unable to meet their Demand in terms of Quality and quantity and it was very expensive. So they started a backward integration to help regulate the quality,meet their Demand and save cost.

In recent times between the late 20th Century till recent times they buy more parts from external suppliers because the cost of managing Internal manufacturing became high because of labor costs and inefficiency caused by lack of competition and Japanese manufacturers have been able to meet their requirements.

ira [324]

An earthquake hits a small island. All but a few individuals of a lizard species are eliminated in this catastrophe, and an allele is lost from the population. This is an instance of the bottleneck effect.

Natural events like an earthquake catastrophe which eliminates, by chance, a large number of individuals of a population, can amplify the phenomenon of genetic drift. It is termed as the bottleneck effect. It leads to the elimination of a large part of the genome abruptly.

Immediately, the survivors' genetic composition becomes the whole population's genetic composition, which might be very distinct from the population that existed before the catastrophe.
