[2] [3] The index is calculated from the results of a complete blood count. If the quotient of the mean corpuscular volume (MCV, in fL) divided by the red blood cell count (RBC, in million per microliter) is less than 13, β-thalassemia trait is said to be more likely. If the result is greater than 13, then iron-deficiency anemia is said to be ...
Hemoglobin in the blood carries oxygen from the respiratory organs (lungs or gills) to the other tissues of the body, where it releases the oxygen to enable aerobic respiration which powers an animal's metabolism. A healthy human has 12 to 20 grams of hemoglobin in every 100 mL of blood. Hemoglobin is a metalloprotein, a chromoprotein, and ...
In a healthy adult male of 75 kg (165 lb) with a blood volume of 5 L, a blood glucose level of 5.5 mmol/L (100 mg/dL) amounts to 5 g, equivalent to about a teaspoonful of sugar. [14] Part of the reason why this amount is so small is that, to maintain an influx of glucose into cells, enzymes modify glucose by adding phosphate or other groups to it.
[1] [2] [3] During gene expression (the synthesis of RNA or protein from a gene), DNA is first copied into RNA. RNA can be directly functional or be the intermediate template for the synthesis of a protein. The transmission of genes to an organism's offspring, is the basis of the inheritance of phenotypic traits from one generation to the next.
Equivalent dose is a dose quantity H representing the stochastic health effects of low levels of ionizing radiation on the human body which represents the probability ...
[3] The disease is widespread in the tropical and subtropical regions that exist in a broad band around the equator. [20] [1] This includes much of sub-Saharan Africa, Asia, and Latin America. [3] In 2022, some 249 million cases of malaria worldwide resulted in an estimated 608,000 deaths, with 80 percent being five years old or less. [21]
[45] [46] The outermost layer is the crust, which is on average about 42–56 kilometres (26–35 mi) thick, [47] with a minimum thickness of 6 kilometres (3.7 mi) in Isidis Planitia, and a maximum thickness of 117 kilometres (73 mi) in the southern Tharsis plateau. [48] For comparison, Earth's crust averages 27.3 ± 4.8 km in thickness. [49]
Around 58.5% of the population are Saudi citizens and 41.5% are foreigners. [3] Located at the core of the Medina Province in the western reaches of the country, the city is distributed over 589 km 2 (227 sq mi), of which 293 km 2 (113 sq mi) constitutes the city's urban area, while the rest is occupied by the Hejaz Mountains , empty valleys ...
