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.

How does the acidity of acid rain compare to the acidity of natural rainwater
jekas [21]

Answer:

The acidity level of water is measured by the pH scale. Pure water has a pH of 7, which is neutral. However, natural rainwater actually has a pH of 5.6 because it gets exposed to the gases in the atmosphere, making it a bit acidic. True acid rain will have a pH level measuring from 5.0-5.5.

Si una población crece mucho otra vez después de un cuello de botella con el paso del tiempo aumentará diversidad genética ¿por
sammy [17]

Answer:

los mecanismos capaces de generar diversidad actúan para incrementar la variabilidad genética en la población que sufrió el cuello de botella

Explanation:

Un cuello de botella se refiere a una reducción drástica en el tamaño de una población (por ejemplo, debido a una catástrofe natural). Un cuello de botella es un fenómeno que está asociado a la ​reducción en la variación genética y fijación de ciertos alelos en la población resultante, lo cual es causado por la deriva genética, es decir, debido al muestreo al azar de los individuos que formarán la población en la siguiente generación. Paulatinamente, los mecanismos capaces de generar variabilidad genética aumentarán nuevamente la diversidad de la población que sufrió el cuello de botella. En una población de reproducción sexual, la variación genética se genera mediante cuatro procesos diferentes: 1-mutación (es decir, la aparición de nuevos alelos debido a alteraciones en la secuencia de ADN); 2-recombinación (es decir, el intercambio de información genética entre cromátidas no hermanas durante la meiosis); 3-segregación independiente de cromosomas durante la meiosis (capaz de producir nuevas combinaciones de alelos) y 4-fertilización al azar (lo cual también incrementa el número de combinaciones entre gametos que darán lugar a un nuevo individuo).
