Answer: Friedreich ataxia is a genetic condition that affects the nervous system and causes movement problems. People with this condition develop impaired muscle coordination (ataxia) that worsens over time. Other features of this condition include the gradual loss of strength and sensation in the arms and legs; muscle stiffness (spasticity); and impaired speech, hearing, and vision. Individuals with Friedreich ataxia often have a form of heart disease called hypertrophic cardiomyopathy, which enlarges and weakens the heart muscle and can be life-threatening. Some affected individuals develop diabetes or an abnormal curvature of the spine (scoliosis).
Most people with Friedreich ataxia begin to experience the signs and symptoms of the disorder between ages 5 and 15. Poor coordination and balance are often the first noticeable features. Affected individuals typically require the use of a wheelchair about 10 years after signs and symptoms appear.
About 25 percent of people with Friedreich ataxia have an atypical form in which signs and symptoms begin after age 25. Affected individuals who develop Friedreich ataxia between ages 26 and 39 are considered to have late-onset Friedreich ataxia (LOFA). When the signs and symptoms begin after age 40 the condition is called very late-onset Friedreich ataxia (VLOFA). LOFA and VLOFA usually progress more slowly than typical Friedreich ataxia.
Red blood cells carry oxygen around the body. These specialized cells are outfitted with the substance hemoglobin, which is a protein, and is the actual oxygen carrying molecule on the cell. The cell has a unique shape that allows it to carry as much oxygen molecules as possible. Red blood cells also transport carbon dioxide away from cells and back to the lungs where the cells are then re-oxygenated.
A wild-type fruit fly exhibits the most common phenotype in the population.
Fruit flies of the wild type are yellow-brown in colour with brick-red eyes and longitudinal black rings across the abdomen.
An organism or strain displaying the wild type is one that has a phenotype, genotype, or gene that predominates in a natural population of organisms or strain of organisms as opposed to that of naturally occurring or laboratory mutant forms.
The genotype and phenotype standards of reference are wild type. Wild type is regarded as the norm and neither the dominant nor the recessive. In compared to the wild type, mutant alleles are either dominant or recessive.
Fruit flies are distinguished by their tiny size, brown bodies, and red eyes. While these pests themselves are not harmful, they may be a sign of unclean living conditions in the home.

Plasma is your answer
Plasma has electrons, which are also located inside lightning bolts, which gives them a negative charge. Through plasma, the lightning bolt is able to travel from the sky towards the ground
