Answer:
La biología es la ciencia natural que estudia la vida y los organismos vivos, es decir, las estructuras físicas, los procesos químicos, las interacciones moleculares, los mecanismos fisiológicos, el crecimiento y la evolución. La biología reconoce a la célula como el componente básico de la vida, a los genes como portadores clave de la herencia y a la evolución como el mecanismo que influye en la creación y extinción de las especies.
Las disciplinas de la biología se definen por los métodos de investigación utilizados y el tipo de sistema estudiado: la biología teórica utiliza la matemática para formular modelos cuantitativos, mientras que la biología experimental realiza pruebas experimentales para examinar la validez de sus teorías propuestas e investigarlas.

Answer:
44
Explanation:
A somatic cell is diploid - it has 46 chromosomes. Half of these are from the mother, so there are 23 maternal chromosomes
A sex cell (gamete) is haploid - it has 23 chromosomes. There are (usually) two sex chromosomes in a diploid genome, either XX or XY, so there is one 1 in a haploid cell, giving a total of 22 autosomes
Barr bodies are inactive X chromosomes in a female somatic cell. This occurs to control dosage compensation (otherwise all the genes on the X in females would be expressed twice as much as they are in males). In a healthy female, there is normally one Barr body
A person with Kleinfelter's syndrome has two X chromosomes and one Y (XXY). They are biologically male, but have two X chromosomes. Therefore, one of these becomes a Barr body, as in females.
23 + 22 - 1 = 44
