Answer:
motor cortex; dopamine
Explanation:
Parkinson's disease is a chronic and progressive disorder of the nervous system, characterized by cardinal signs of stiffness, akinesia, bradykinesia, tremor and postural instability. It has an idiopathic etiology, but it is believed that its emergence comes from environmental and genetic factors, and may interact and contribute to the neurodegenerative development of Parkinson's disease. Parkinson's disease is a condition of the central nervous system, which is chronic and progressively expressed. It results from the death of dopamine-producing neurons in substantia nigra. As the disease progresses, the motor cortex begins to produce less dopamine. The result of this is the worsening of the symptoms of the disease.
Based on this, regarding Jeremy's case, we can conclude that it is likely that Jeremy's motor cortex is producing less dopamine than necessary, so he is experiencing worsening symptoms of Parkinson's disease.
During vegetative propagation, a new plant grows from parts of the parent plant.
During mitosis, a cell divides to produce a new, genetically identical cell.
Explanation:
Both vegetative propagation and mitosis are methods of asexual reproduction followed by various organisms. In both the methods, only a single parent is involved in the reproduction of new daughter cells.
Vegetative reproduction is the asexual reproduction in plants with the formation of a new plant from the existing structures of the parent plant. These structures include rhizomes, bulbs, tubers etc.
Mitosis is a type of cell division which leads to the formation of genetically identical daughter cells similar to their parents. This occurs due to replication of the chromosome which then splits to form two identical daughter cells each with the complete set of chromosomes.
Hello!
Primary sources are the best sources to hear from. Young people will know best about how young people are affected by violence, as they are young people themselves and may some sort of experience with being affected by violence.
Hope this helps!
