Answer:
Nucleotides are organic molecules consisting of a nucleoside and a phosphate. They serve as monomeric units of the nucleic acid polymers deoxyribonucleic acid (DNA) and ribonucleic acid (RNA), both of which are essential biomolecules within all life-forms on Earth.
Explanation:
Ion transport or active transport depending on which situation you have.
I agree with the person above - reproductive cells or sex cells are called gametes.
When it comes to women, these gametes are called an ovum, or an egg, and when it comes to men, gametes are called sperm.
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.
Answer:
La respuesta correcta es "a. arterias, b. venas; y c. capilares".
Explanation:
Los vasos sanguíneos son una serie de conductos a través de los cuales el cuerpo transporta la sangre, asegurando que todas las células del cuerpo tenga acceso a oxígeno, elemento necesario para la respiración celular. Hay tres tipos de vasos sanguíneos: arterias, venas y capilares. Las arterias llevan la sangre del corazón a los órganos, las venas transportan la sangre de los órganos al corazón y los capilares son vasos muy pequeñitos que llegan a las partes más pequeñas del cuerpo.
