kap26 [50]

Answer: Based on the information, the person DOES NOT have lactose intolerance because glucose levels significantly increases in normal individuals after a lactose rich meal.

Explanation:

Lactose is a disaccharide carbohydrate which when taken (found mostly in diary products) is hydrolyzed by lactase into its monomers, which are then absorbed into the blood. The hydrolysis of lactose gives glucose and galactose which is carried out by the digestive enzyme lactase. Deficiency of the lactase enzyme gives rise to a disorder known as LACTOSE INTOLERANCE.

The diagnosis of lactose intolerance or lactase deficiency can be confirmed by measuring the plasma glucose concentrations, as in glucose tolerance test, after giving an oral load of lactose rich solution. If the disaccharide (lactose) cannot be hydrolysed, the constituent monosaccharides cannot be absorbed and the concentrations of plasma glucose rise VERY little.

But the fasting blood glucose done after 2 hours of drinking a lactose rich solution showed a typical rise in blood glucose levels which were 80, 90, 100, 110 and 120 mg/ dL tested for every 30 minutes. This indicates that the individual does not have lactose intolerance because the glucose gotten from hydrolysed lactose was absorbed and cause a significant rise in blood levels.

<span>Survival of at least a few members of a population after a major environmental change is most dependent on 3) variations in many different traits in many individuals in the population.
Variation is important for a species which wants to survive huge changes in the environment. If they cannot adapt to their new surroundings, they won't be able to survive. This is where variation comes in - it enables a species to develop new techniques and traits necessary for survival.

The metamorphosis of a tadpole to an adult frog involves a thorough reconstruction of the animal's body. Positive feedback regulation would ensure that the animal completed its transformation.

Positive feedback regulation of prothoracic hormone secretion by ecdysteroids is the mechanism that determines the timing of metamorphosis.

Metamorphosis is the biological process by which an animal develops physically, including birth and hatching, and which involves marked and relatively rapid changes in an animal's body structure due to cell growth and differentiation.

Some insects, fish, amphibians, mollusks, crustaceans, cnidarians, echinoderms, and tunicates undergo metamorphosis, often with changes in diet and behavior.

In case of frogs, and toads, forelimbs are formed under the gill pouch, and the hind limbs are visible after a few days. This is usually followed by a longer phase in which the tadpoles are fed a vegetarian diet.

Tadpoles use a relatively long spiral intestine to digest this food. Recent studies suggest that tadpoles do not have a balanced homeostatic feedback control system until early stages of metamorphosis.

At this point, their long intestine shortens and they prefer insects.
