Answer:
Dopamine
Explanation:
Parkinson’s disease is a degenerative, progressive disorder that affects nerve cells in parts of the brain called the basal ganglia and the substantia nigra.
The neurotransmitter dopamine is produced by nerve cells in the substantia nigra and these nerve cells function in relaying information from the brain that plan and control body movement. In Parkinson's disease, the dopamine-producing nerve cells of the substantia nigra begin to die off . Symptoms such as tremor, impaired movement, stiffness, and balance problems occur when the loss of nerve cells is about 80%
Answer:
The axial filament is located between the cell membrane and the outer membrane.
Explanation:
Axial filaments are structures used for motility too. They wraped around the cell body and are found in spyrochetes. The origin of the flagella is in the periplasmic space, the space between the inner membrane and the outer membrane they differ because other flagellum are near the cell surface, attached to the basal body enclosed in the cell envelope.
Answer:
Meiosis
Explanation:
Mitosis and meiosis are both types of cell divisions.
In mitosis, a parent cell undergoes one division and produces an identical, diploid cell. This results in 2 daughter cells.
In meiosis, a parent cell undergoes two divisions. This produces unique, haploid cells. The result is 4 daughter cells that are not identical to the parent cell.
Therefore, the answer is meiosis. Meiosis produces four daughter cells.
Ans ; It would have to be closer for it to be in a circular orbit twice as fast. One moon cycle would be 2 weeks instead of 4 so our months would have been based on 2 week cycles making for 24 months. Tides would be less synchronous between days and much more intense because of how close it would be. This would have left a very different land map. Tidal forces would force the moon to rip apart sooner than with it's present orbit creating an important ring system around earth earlier.
