Landsteiner Bertillon devised a technique for determining the blood group of a dried bloodstain, which he applied to criminal investigations.
<h3>
What about blood group?</h3>
- According to the presence or absence of antibodies and hereditary antigenic compounds on the surface of red blood cells, blood is classified according to its type.
- Depending on the blood group system, these antigens could be proteins, carbohydrates, glycoproteins, or glycolipids.
- The genes that a person got from their parents determine what blood type they have.
- There are numerous systems for classifying blood types, but ABO is the most popular one.
- The ABO group is divided into four main categories: A, B, O, and AB.
- There are eight more blood types within these groupings.
- Each of the eight blood types has a particular ability to save lives.
- The majority of people (37% of the population) have the blood type O+, which is the most prevalent. This indicates that there is a greater need for this blood type for blood transfusions.

Biodiversity generally refers to the variety and variability of life on Earth. According to the United Nations Environment Programme(UNEP), biodiversity typically measures variation at the genetic, species, and ecosystem level.[1] Terrestrial biodiversity tends to be greater near the equator,[2] which seems to be the result of the warm climateand high primary productivity.[3] Biodiversity is not distributed evenly on Earth, and is richest in the tropics. These tropical forest ecosystems cover less than 10 percent of earth's surface, and contain about 90 percent of the world's species.[4] Marine biodiversitytends to be highest along coasts in the Western Pacific, where sea surface temperature is highest, and in the mid-latitudinal band in all oceans. There are latitudinal gradients in species diversity.[5]Biodiversity generally tends to cluster in hotspots,[6] and has been increasing through time,[7][8] but will be likely to slow in the future.[9]
Rapid environmental changes typically cause mass extinctions.[10][11][12] More than 99.9 percent of all species that ever lived on Earth, amounting to over five billion species,[13] are estimated to be extinct.lstimates on the number of Earth's current species range from 10 million to 14 million,[f which about 1.2 million have been documented and over 86 percent have not yet been described] More recently, in May 2016, scientists reported that 1 trillion species are estimated to be on Earth currently with only one-thousandth of one percent described.[18]The total amount of related DNA base pairson Earth is estimated at 5.0 x 1037 and weighs 50 billion tonnes.[19] In comparison, the total mass of the biosphere has been estimated to be as much as 4 TtC (trillion tons of carbon).[20] In July 2016, scientists reported identifying a set of 355 genes from the Last Universal Common Ancestor (LUCA) of all organisms living on Earth.[21]
The age of the Earth is about 4.54 billion years.[22][23][24] The earliest undisputed evidence of life on Earth dates at least from 3.5 billion years ago,[25][26][27] during the Eoarchean Era after a geological crust started to solidify following the earlier molten HadeanEon. There are microbial mat fossils found in 3.48 billion-year-old sandstone discovered in Western Australia.[28][29][30] Other early physical evidence of a biogenic substance is graphite in 3.7 billion-year-old meta-sedimentary rocks discovered in Western Greenland.More recently, in 2015, "remains of biotic life" were found in 4.1 billion-year-old rocks in Western Australia.[32][33] According to one of the researchers, "If life arose relatively quickly on Earth .. then it could be common in the universe.
decreased and then increased after major waves of mass extinctions
Answer is.
Since there are no confirmation yet and the client is still in diagnosis if whether the client has it or not, it is best that the nurse should ask the client to do and maintain his or her activities in an adequate phase. It is also advisable that the nurse should advice the client to prevent doing things that could be of risk of muscle atrophy.
Anemia is a blood disorder caused by a lack of iron and red blood cells.
Anemia impedes the production of protein hemoglobin in the body because of the absence or lack of the mineral iron in the blood. Iron is needed to produce the protein hemoglobin which in turn helps the red blood cells carry oxygen from the lungs and transport it all throughout the body.
