Letter A, Electron microscope

Explanation:

The electron microscope is used to visualize high-resolution images of biological specimens. It used to see in detail very small  cells, organelles, cells tissues,  molecular complexes, etc. The ribosome is a complex molecule made of proteins where the translation of proteins is made, it is very small that can be seen in detail using the electron microscope.

Lactose when digested, it is hydrolyzed by lactase into its monomers, which are then absorbed by blood. Following are test resul
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.

What is the solubility of NH4Cl at approximately 50.0 oC?
Semenov [28]
We can define the solubility as the maximum amount of solute (which may be a solid, liquid or gas) that is dissolved in a solvent ( which may be a solid, liquid or gas).
The solubility of Ammonium chloride (NH₄Cl) at 50°C is 50 grams, because t<span>he </span>solubility of NH₄CL<span> is 50g /100g of water at </span>50°<span> C.</span>
