46 Cromosomas
Las células del ser humano tienen 23 pares de cromosomas, 22 pares de autosomas y un par de cromosomas sexuales. Por tanto, cada individuo tiene 46 cromosomas en sus células. Por lo tanto, el número de cromosomas presentes en una célula nerviosa de un ser humano es de 46 cromosomas.
This
reserve is home to terrestrial and marine mammals, including grizzly
and polar bears, caribou, wolves, and wolverine as well as beluga and
bowhead whales, walrus, and several species of seals. It was
established for the purpose of preserving unique wildlife,
wilderness, and recreational values.
The
most complex level of organizational hierarchy in the Arctic National
Wildlife Refuge that is preserved is every ecosystem in the area.
I
hope it helps, Regards.
The energy transformation that takes place during cellular respiration is the conversion of glucose (chemical energy) to another form of compound with high energy bonds (adenosine triphosphate) that can be readily used by the body.
All energy on Earth comes from the sun. From this, photosynthetic organisms produce organic glucose from inorganic compounds such as water and oxygen. These producers will then be consumed by consumers and the energy will be passed from prey to predator. In cellular respiration, the energy from the sun is stored in the form of high energy chemical bonds that is broken to release energy and formed to store energy.
The child mice will inherit gemes from the parental mices fur, therefore having a similar or exact type of fur.
1. Two examples of genetic disorders are CYSTIC FIBROSIS AND SICKLE CELL ANEMIA.
CYSTIC FIBROSIS
Cystic fibrosis is typically inherited when a defect occur in the CFTR gene of an individual. The CFTR gene is responsible for production of a protein that regulates the movement of water and salts out of the body cells. This gene does not perform optimally in people who have cystic fibrosis and this leads to the production of thick, sticky mucus and extremely salty sweat. Individuals who have this disease usually inherit two copies of the defective gene, one from the father and the other one from the mother.
2. SICKLE CELL ANEMIA
Sickle cell anemia is a genetic disorder of the blood, which is cause by inheritance of two copies of abnormal hemoglobin from parents. The hemoglobin is responsible for movement of oxygen all through the human circulatory system. The abnormal hemoglobin causes defective red blood cells, which can not move oxygen around efficiently. Thus, individuals with this disease do not usually get enough oxygen in their blood, this leads to fatigue and chronic pains plus several other negative medical conditions.
